Abstract:
The main material of concrete is a construction building material composed of water and mineral mixture and cement and chemical additives in the corresponding proportion and below the standard. In the process of making concrete material, slurry and cement are needed to mix, then cement slurry and sand are mixed into mortar according to the corresponding proportion, and aggregate is added to mortar to form concrete building material. In the process of concrete preparation, the most important construction link is mixing, which needs to be fully stirred to make the performance of concrete meet the construction needs. In the process of concrete construction technology development, both mix ratio and production technology have become more and more mature, but there are still some problems, which have an impact on the quality of concrete. Therefore, this paper discusses the quality control of concrete raw materials according to the construction process of road and bridge.

Abstract:
Signal processing approaches are widely used in the field of earthquake engineering, especially in the identification of structural modal parameters. Hilbert-Huang Transformation (HHT) is one new signal processing approach, which can be used to identify the modal frequency, damping ratio, mode shape, even the interlayer stiffness of the shear-type structure, incorporating with Natural Excitation Technique (NExT) method to take information from the response records of the structure. The stiffness of the structure is of great importance to judge the loss of its bearing capacity after earthquake. However, all of modal parameters are required to calculate the stiffness of the structure by use of HHT and NExT, which means that the response records shall contain all of modal information. However, it has been found that the responses of the structure recorded only contain the former order modal information; even it is excited by earthquake. Therefore, it is necessary to found a formula (formulas) to calculate the stiffness only using limited modal parameters. In this paper, the calculation formulas of the interlayer stiffness of shear-type structure are derived by using of the flexibility method, which indicate that all of interlayer stiffnesses could be worked out as long as any one set of modal parameters is obtained. After that, Taking Sheraton-Universal Hotel subjected to North Bridge earthquake in 1994 as an example, HHT and NExT are used to identify its modal parameters, the derived formulas are used to calculate the interlayer stiffnesses, and their applicability and accuracy are verified.

Abstract:
Carbonate rock has the characteristics of complicated accumulation rules, large-scale development, high yield but unstable production. Therefore, the management and control of surface engineering projects of carbonate rock oil and gas reservoirs faces huge difficulties and challenges. The construction of surface engineering should conform to the principle of integrated underground and ground construction and adapt to the oilfield development model. This paper takes the newly added area A of the carbonated oil field as an example to study the ground engineering under the rolling development mode and aims to provide the constructive ideas for the surface engineering under rolling development mode. The overall regional process design adheres to the design concept of "environmental protection, efficiency, and innovation", strictly follows the design specifications, and combines reservoir engineering and oil production engineering programs, oil and gas physical properties and chemical composition, product programs, ground natural conditions, etc. According to the technical and economic analysis and comparison of area A, this paper has worked out a suitable surface engineering construction, pipeline network layout and oil and gas gathering and transportation plan for area A. Some auxiliary management recommendations are also proposed in this paper, like sand prevention management and HSE management for carbonate reservoirs.

Abstract:
The professionalism of real estate development makes the decision-making environment of development relatively complicated. Building the decision model can help investors make reasonable decisions in real estate development. This paper analyses the construction project of Berlin Brandenburg Airport by using the agency role-based model of real estate development proposed by Adams & Tiesdell. The research found that the existing research is looking for different objective factors from real estate development cases, without analysing the influence of actors involved in the development process on the entire real estate development decision. In the process of real estate development, not only the changes in the market environment should be considered, but also the influence of different roles on decision-making in the development process. The conclusion of this paper provides a useful supplement to the real estate development model and proposes specific improvement measures.

Abstract:
Under the rapidly advancing economic trends, people’s requirements for the functionality and architectural artistry of high-rise structures are constantly increasing, and in order to meet such modern requirements, it is necessary to diversify the functions of high-rise buildings and complicate the building form. At present, the main structural systems of high-rise buildings are: frame structure, shear wall structure, frame shear structure, and tube structure. Different structural systems determine the size of the load-bearing capacity, lateral stiffness, and seismic performance, as well as the amount of material used and the cost. This project is mainly concerned with the seismic design of frame shear structural systems, which are widely used today.

Abstract:
It’s a compressive article consists of three parts, an overview of pipeline development in China, oil pipeline design for R oilfield and pipeline management suggestions. First, this article introduces the current status of pipeline construction, oil pipeline technology and gas pipeline technology in China in recent years. The current status of China’s pipeline construction is divided into three stages. In terms of construction, pipeline construction is developing in the direction of intelligence and modernization. Long-distance oil pipelines require technical breakthroughs in two aspects. One is the sequential oil product delivery technology to improve the type of oil that can be delivered sequentially; the second is the viscosity reduction delivery technology for heavy oil. Gas transmission pipelines are developing in the direction of high pressure, large diameter and high steel grade. Secondly, based on all the pipeline development above, in order to meet the development of R oil field, an oil-water two-phase pipeline transportation design and a pipeline crossing river design were carried out. Under the condition of the design pressure of the pipeline of 5.5MPa, it is preferable to produce a pipeline of φ219×6.5mm, and the steel grade of the pipeline is L360. A heating station and pumping station are needed in the transportation process, and the heating station and pumping station are combined for one construction. Considering that the strata of the river crossing section are mainly gravel sand layer, clay layer and non-lithological stratum, horizontal directional drilling (HDD) is adopted for river crossing, and suggestions are made for the construction process. Finally, after the pipeline was put into production, the corresponding auxiliary production system and supporting engineering suggestions were put forward.

Abstract:
The Hong Kong-Zhuhai-Macao Bridge(HZMB) project, which has just been opened to traffic in 2018. The special location, construction conditions, quality requirements and multiple functions of HZMB brought many challenges, such as management, technology, safety and environmental protection. To meet these challenges and ensure the achievement of high quality and 120 years design service life, the HZMB project first introduced the completely new concept of "Large size, Factory production, Standardization and Assembly", which was fundamental to the design and construction. This was developed in consideration of the difficulties of the offshore environment.The core idea was Prefabrication and Assembly, which was to change this HZMB project into onshore work as much as possible by cutting this mega sea-crossing into large sized components, which could be prefabricated on land and then transported to the offshore site for assembly. The success of the HZMB undoubtedly has led the technology of prefabrication and assembly to a new height and recognized scale. This paper describes the implementation process of the concept; "Large size, Factory production, Standardization andAssembly" (LFSA) to the HZMB.

Abstract:
With the continuous implementation of the PPP projects, due to the imperfection of relevant policies, the blindness of government subsidy is constantly emerging. Thus, it is important to put forward a practical approach for valuing the subsidies and risk. In this paper, the revenue subsidies model and traffic subsidies model are established. Then combined with practical cases, Monte Carlo simulation is used to get the value and probability of government subsidies under different compensation ways. On this basis, the influence of initial traffic volume and traffic growth rate on government subsidies and net present value of investors is analyzed. The research findings can provide theoretical guidance for the government to choose a reasonable way of subsidies, balance the risk of compensation, and formulate subsidies policies.

Abstract:
After decades of civil war, Yemen is in a desperate situation, and the construction industry has been suffering from low productivity and poor performance. In order to improve the productivity for the Yemeni construction industry, Construction enterprises must adopt the best and new technologies, new management concepts and philosophies such as Total Quality Management (TQM) and concurrent engineering (CE) owing to achieve improvements in the process of product development. To ensure the successful implementation of CE in the Yemeni construction industry, it is necessary to assess the readiness of those companies to implement CE. In this paper, the BEACON model is used to assess the readiness of the Yemeni companies to implement the concept of CE, that assist in overcoming the construction industry's poor productivity and performance. A study assessing CE implementation readiness will help to promote successful CE implementation in the construction industry and enhance the efficiency of construction companies. The results show that most of the construction companies in the Yemen are not ready to implement CE. The main reason is that the enterprises rely heavily on traditional management methods, and need to improve the organization and management technology. The research results can provide theoretical support for construction companies, especially Yemen companies, to establish basis in implementing an appropriate CE approach for improving performance, and also help international construction companies entering the Yemen construction market to cooperate and implement CE.

Abstract:
Building collapse mostly can be caused by the loss of loading capacity in a primary structural component, resulting in the failure of surrounding elements, which in turn cause a failure propagation. Progressive collapses may be accidental, due to design deficiencies or errors, material failure or natural phenomenon (e.g. earthquakes) but it can be prevented by upgrade the concrete components’ material [1][2]. Well-engineered RC buildings generally have a good performance under normal loading conditions. However, faulty design, construction errors, material deterioration, and overloading are always occurred. When part of structure fails, the total load in the whole system will not disappear, which means the load will be redistributed unevenly to the adjacent part of structure. This phenomenon revealed that sustained high stresses in RC elements can lead to catastrophic collapse. Due to very few of papers did the research on the RC elements under high stress level sustained load, relevant experiments should be performed in this area. This paper gives the suggestions about how to apply the load in an experiment if researchers want to know the behavior of elements near to collapse especially focus on RC columns.

Abstract:
The decision of traffic congestion degree is an important research topic today. In severe traffic jams, the speed of the car is slow, and the speed estimate is very inaccurate.This paper first uses the data collected by Google Maps to reclassify road levels by using analytic hierarchy process. The vehicle speed, road length, normal travel time, traffic volume, and road level are selected as the input features of the limit learning machine, and the delay coefficient is selected. As the limit learning machine as the output value, 10-fold cross-validation is used. Compared with the traditional neural network, it is found that the training speed of the limit learning machine is 10 times that of the traditional neural network, and the mean square error is 0.8 times that of the traditional neural network. The stability of the model Significantly higher than traditional neural networks.Finally, the delay coefficient predicted by the extreme learning machine and the normal travel time are combined with the knowledge of queuing theory to finally predict the delay time.

Abstract:
Finite element simulations were conducted to explore the effects of high temperatures on the loading capacity of slab-column connection for the concrete flat-plate structures by the finite element analysis software ABAQUS. The structure used for the simulation is a slab which thickness is 150 mm with a 300 mm square column in the middle of slab, the column height is 450mm. The size of this slab is the same as experiments conducted by previous paper [1]. Based on the results of simulation, the punching capacity of this structure not experienced high temperature can be predicted with very good accuracy. But the result from simulations underestimated the loading capacity of the this structure after it has been cooled by around 10%. This phenomenon is a little bit conflicts with the known experimental results, however, it can be adjusted by modify the material parameters built-in the software. This article is focus on how to best simulate the concrete behavior for both linear and nonlinear part under the room temperature and cooling after experience a very high temperature.

Abstract:
The warheads such as missiles and artillery shells have a certain speed of motion during the explosion. Therefore, it is more practical to study the explosion damage of ammunition under motion. The different speeds of the projectiles have a certain influence on the temperature field generated by the explosion. In this paper, AUTODYN is used to simulate the process of projectile dynamic explosion. In the experiment, the TNT spherical bare charges with the TNT equivalent of 9.53kg and the projectile attack speed of 0,421,675,1020m/s were simulated in the infinite air domain. The temperature field temperature peaks and temperature decay laws at different charge rates and the multi-function regression fitting method were used to quantitatively study the functional relationship between the temperature and peak temperature correlation calculations of static and dynamic explosion temperature fields. The results show that the temperature distribution of the dynamic explosion temperature field is affected by the velocity of the charge, and the temperature distribution of the temperature field is different with the change of the charge velocity. Through the analysis and fitting of the simulation data, the temperature calculation formula of the static and dynamic explosion temperature field is obtained, which can better establish the relationship between the temperature peak of the static and dynamic explosion temperature field and various influencing factors, and use this function. Relational calculations can yield better results and meet the accuracy requirements of actual tests.

Abstract:
Landscape is people’s evaluation of the environment which is better and more meaningful to visit. Therefore, a landscape must have a good environment. Landscape exists in nature as well as in cities. Every corner of a city can be a landscape. Its connection with the city and the citizens is inseparable. However, due to the acceleration of urbanization, there are still many problems in the urban environment. To solve these problems perfectly, we should work from the aesthetic value and planning orientation of the landscape. Therefore, this paper discusses and analyzes the problems of urban environment and how to use the aesthetic value and orientation to construct urban environmental landscape.

Abstract:
The prevalence of surface contaminants, such as potentially harmful bacteria, within building environments in the State of Kuwait is not known.To the authors’ knowledge, this article is the frst of such a report. A total of 342 stool samples were collected from 46 secondary schools to evaluate indoor occurrences of E. coli bacteria within selected lavatory surfaces. After microbiological testing, the results for the spread of the E. coli bacteria were categorized by total count, sampling location dependency, contamination level comparison between genders, and lavatory fxtures (i.e. seat and squat toilets). The results revealed that 7 schools have a bacterial contamination problem, there is cross-contamination between surfaces in the lavatory stalls, the boys’ lavatories were less sanitary than the girls’, and that the squat-style toilets are more contaminated than the seat-style. The results suggest that there is signifcant risk of spread of bacterial infection among students via contaminated hands and surfaces in the lavatory area in some schools. Thus, this study emphasizes the need to improve environmental hygiene and enhanced sanitation in these schools. In addition, conclusions can be drawn as to the effectiveness of the janitorial staff employed by the schools and the effcacy of the cleaning regime used in the lavatories. Furthermore, based on the fndings, there are architectural design consequences as squat-style toilets might be excluded in lavatories designed for schools to be constructed in the future.

Abstract:
In this study, indoor quality and environmental comfort were investigated in secondary school buildings located in the State of Kuwait. Comfort variables such as temperature and relative humidity (thermal comfort), noise (acoustic comfort), illumination (visual comfort), as well as allocated classroom floor area per student (spatial comfort) were measured. Data was collected over a 7-month period on a spot basis during school hours in student-occupied classrooms at 46 selected schools. The measured data was then compared to international guidelines and standards related to indoor environment quality. The data for noise and allocated space were shown to be in the comfort ranges in all the schools. However, 11% of the schools are not adequately illuminated, 33% had temperatures not within the recommended limits, and 22% of the schools had humidity levels either higher or lower than the recommended levels. Also, 9% of the schools had low illumination readings.In addition, during the data monitoring, a survey was conducted by which the student occupants completed a questionnaire so that subjective and objective evaluations could be compared. The findings of the questionnaire displayed significant correlations between the measured data and some ailments and other complaints experienced by the students.Ultimately, the results found in this research will provide a baseline for comparison with future indoor environment quality assessments in buildings. Furthermore, recommendations are suggested in order to improve the environmental quality problems encountered in some of the schools, which may be beneficial for policymakers, facilities managers, and design engineers.

Abstract:
The green belt, located on the outskirts of a metropolis, has many characteristics such as good location, better landscape environment than urban areas, high availability in an original environment, low development costs and large and concentrated open spaces. With the huge population in China, this has led to a shortage of green space per capita and the shortage of recreational space. In view of such conditions, the recreational function of the green belt is very important, and can compensate for the shortcomings of tight urban recreation space. However, there has always been an important question about the scientific aspects and rationality of green belt use and control measures. In this paper, some outcomes of the Chinese green belt policy will be introduced. Then, three advantages and two disadvantages will be shown. Finally, reasons analyse and comparisons between China’s main cities and cities with a successful green belt will be given.
