In general, the buildings are designed based on the applied loads on them, and these buildings generally have elastic structural behaviour. However, these structures may be subjected to unexpectedly strong seismic forces that exceed their elastic limits. In order to find the rigidity and load-bearing trend of the building without the formation of plastic hinges and failure, pushover analysis should be performed. Pushover analysis is a non-linear static analysis in which the structure is subjected to lateral loads, so some parameters are recorded, such as failure, formation of plastic hinges, and yield. The elastic stiffness factor is the ability of a building to bear the loads on it before the failure and existent of the plastic hinges. In this study, pushover analysis had been done on 12 two-dimensional reinforced concrete frames with a different number of stories, different span lengths and with or without shear walls to find the effect of the span length, shear wall and the number of stories on the elastic stiffness factor. After performing the pushover analysis, the elastic stiffness factor had been evaluated from the pushover curve by dividing the base shear over the lateral displacement at the first point of the occurrence of the plastic hinge. The results obtained from the study showed that the elastic stiffness factor increases with the increase of the span length, while it decreases with the increase of the number of stories. As well, the frames with shear walls are stiffer than the frames without shear walls.

Wastewater treatment plant (WWTP) is considered one of the most dangerous sectors in the industrial field. Many workers still die each year due to poor awareness of workers about occupational health. Safety performance became important for different projects in the industrial field. Safety performance is concerned about the general behaviour of the workers in the worksite, usually, the performance can be evaluated by managing systems and identifying health hazards that can happen in the field. Many researchers tried to summary different methods to rate the safety performance. This paper describes the significant topics in risk assessment and hazard identification that have been done in the field of wastewater treatment plant (WWTP). The collected investigations have been arranged and sorted in this paper to set up strong basic information for the works in the field. Unlike the other studies, this paper is focused mainly on the safety performance, health hazard and risk assessment in the wastewater treatment plant (WWTP). This study has found the specific factors that can affect the performance of workers since the workers in general workplaces are facing difficulties in determining the hazards that can be resulted in serious problems such as injuries and death.

The ductility of a structure is an important factor that should be taken under consideration in the design against lateral loads like an earthquake. This paper presents the effect of the shear wall on the ductility of the structure and the effects of the presence of opining in it on the ductility. Eighteen 2D moment-resisting frames (MRFs), with the shear wall (SW) and SW with opening structural models, were created and designed. The pushover analyses using ETABS 19 software were performed on the designed models to calculate the ductility of the structural models. The obtained results show that the shear wall in the models increases the ductility of the structures significantly, while the presence of an opening decreases it slightly. Besides, the increase in the number of storeys increases the ductility of MRF models but decreases the ones with SW. Oppositely; the increase in span length reduced the ductility of MRF models and increases the docility of the models with SW

The construction industry is one of the most significant industries that contribute greatly to achieving economic development. However, it is also considered one of the industries that is always exposed to a high risk of hazards in addition to being full of risky activities. Accidents that occurred in construction industries have caused many defects in project progress, for example, delays in completing the project, increasing project cost, reducing productivity, and creating negative impressions about the company. The major reason for the accidents is poor worker safety performance, with a host of contributing causes. For improving safety performance, the root causes of incidents that occur in construction as well as the factors influencing them must be studied. Health and safety issues are the main problem and concerns in the building industry. Though much development has been made in construction safety, the industry still lacks a lag behind most other industries in terms of safety. The aim of this paper is to provide a comprehensive review of the factors that could affect the safety performance of a construction site to reduce the frequency of accidents.

These days, risk management and analysis are serious issues in the effective management of construction projects, because construction projects are likely to be very dynamic, productive, diverse and increasingly competitive. Risk management helps project parties such as clients, contractors and vendors/suppliers to meet their obligations to reduce negative impacts on their works. The outcomes of the risk management method include the analysis and detection of risks, the creation of building project management systems and the efficient use of resources. The aim of this article is to find out how the Somalian construction companies see the value of construction project risks and how to manage it by dispatching a questionnaire. The total questions of the questionnaire are seventeen questions and were distributed by various participants such as clients, contractors and designers. The findings show that in the implementation of risk management techniques, the Somalian construction industry varies greatly from building companies in foreign countries. The contractor needs to consider risk obligations, dynamics of risk incidents, risk tolerance and risk control skills to handle the risks effectively and efficiently. Due to the insufficiency of experience in the attitude of Somalian entrepreneurs towards risk management is very hard to change. However, as a component of their project management, the construction companies must include risk analysis in projects. The application of risk management in Somalian construction companies is small to moderate, with little difference between organizations' types, sizes and risk tolerances and individual respondents' experience.

Jacket platforms are one of the most important and regularly used types of offshore structures for oil and gas extraction that have a big impact on the economy of the countries. In this paper, all aspects including design, analysis, construction and installing of the jacket type offshore structure, are summarized and classified. This type of structure is one of the specified platforms for shallow water, and for long term service, it also has the ability to carry large deck loads. This paper aims to present general guidance about the planning, design and construction of offshore jacket (template) platforms. Jacket platforms are fixed type platforms which are attached to the seabed using piles which provide stability against the wind, wave and current loads. Also, this type of offshore platform has a high initial and maintenance cost because of its exposure to corrosion, and cannot be reused after the end of its service period. Jacket platforms are most suitable for shallow water having no better alternative while it has the cost disadvantage for deep water.

Offshore structures are used around the world for many functions, and these structures vary according to the depth of the water, the depth of water and environmental conditions are the main factors that determine the type of platform and method of drilling, appropriate planning, manufacturing, transportation, installation, and start-up. At the beginning of the twentieth century, oil and natural gas were discovered in the Middle East, specifically in the Lebanese basin. This discovery opened the door for Lebanon and entered the club of oil states. This paper is a study and analysis of blocks No. 4 and No. 9 that may contain the largest amount of oil and natural gas in addition to studying and analysing the types of marine installations (fixed and movable) and provide the best suggestions for the type suitable platform for the process of extracting oil and natural gas from the Sea of Lebanon according to the depth of water and factors Natural. The option of a drillship for drilling is the most appropriate option, given the lack of sufficient information about the nature of the soil in the Lebanese Sea. The drillship is considered an optimal solution given for ease of movement and in the absence of oil, the cost is much lower than the installation of fixed platforms. Semisubmersible rig for drilling and Tension Leg Platform or Semisubmersible Platform as well as Subsea System for oil/gas extraction are good alternatives to be employed in the Lebanese oil/gas fields.

When someone decides to buy a house or any other estate near the shoreline, they do not think that in future nature will impact the value of their asset significantly. Further to the risks of hurricanes or any other natural hazards (such as tsunami), waves are gradually shifting the coastlines by displacing soil from a location to various areas. In recent decades, coasts have been affected by a significant deterioration due to weather conditions, waves, and coastal soil erosion. Hence, it needs precise environmental consideration, and preserves coasts for leisure, specifying reasons that promoted effective technologies from immersed structures to coastal nourishing. Therefore, by constructing sea-walls should prevent shoreline environments, especially the mechanism of sedimentation, long-shore transfer of sand, altering the coasts to the significant proportion which results from weathering and sea waves sever. In this paper, an overview submitted to the kinds of seawalls and specifications needed to sustain the seawalls. There explained the positive and negative effects of seawalls on coastal area, and the required factors to enhance seawalls stabilization against overturning and sliding failure. Also, the developed types of seawall structures have been identified that, in addition to the more practical vertical model, the stepped, rubble-mound, and curves have also been designed. It is recommended to coastal structure designer and engineers, in the pre-construction stage should precisely be studied on the coast situation and weathering conditions in the area, that is essential to make sustainable decisions and designs for construction of these structures.
