Abstract:
The COVID-19 pandemic drastically altered traffic patterns across the globe. With more people staying at home and relying on delivery services, there was a reduction in passenger car traffic but an increase in freight traffic. This study investigates the changes in traffic volume and mode splits during the COVID-19 pandemic at the intersection of Broening Highway and Holabird Avenues and investigates traffic signal reallocation strategies that account for the changes in traffic. This study considers morning peak traffic volumes before and during COVID. A methodology was developed to evaluate and measure freight volumes and emissions. From the literature, the cost per kilogram of CO, VOC, and NOx was $5.85,$3,37, and \$12.53, respectively. The intersection operated at a level of service (LOS) of C both pre-COVID and during COVID. Traffic volume decreased by 24.3% during COVID at the study location; car volumes declined by 50%, and truck volumes increased by 130%. The total rate of emissions decreased by 22.6%.

Abstract:
The numerical analysis of static and dynamic performance of embankmentdams using the finite difference approach is a complex procedure that takesinto account material behavior, soil-dam foundation interaction, hydraulicconditions, and saturation effects. In this study, a numerical analysis usingthe finite difference method (FLAC 3D) is used to conduct a static anddynamic analysis of the Keddara earthen dam in the Boumerdes regionof Algeria, with the goal of defining its behaviour in terms of settlement,deformation, and pore pressure variation during construction and operation.There are two steps to consider: dam construction and water filling. Forthe static analysis, two mathematical models are considered: the elasticmodel and the Mohr-Coulomb model. An actual earthquake record isused to conduct a coupled dynamic analysis, and the interaction betweenthe fluid and solid phases is taken into account. Maximum displacement,acceleration, and pore pressure remain inconsequential for dam instability;horizontal and vertical displacements increase with distance from the dambody’s base to the top.

Abstract:
A knot is the joining place between two or more constructive elements in a framework or structure. They have a fundamental importance in the structure, according to their design they will be able to give a geometric configuration or another to the system and will also absorb certain forces or others. Depending on the movements they allow to the bars, there are rigid knots, articulated knots and slip knots. In this paper a study of cases about rigid knots or embedments used by structural systems so far will be presented. These types of knots prevent the rotation and movement of the constructive elements used for construction. In this paper also a study of cases about the articulated and slip knots used by transformable structural systems so far will be presented. An articulated knot allows the rotation but not the movement of the elements. A slip knot prevents movement in one of the three axes of the reference system, but not in the others, nor in the rotation between the elements. The research is focused in presenting a summary and comparison of rigid knots, articulated knots and slip knots that have been used in the structural design of some architecture. The union systems research will be crucial in this study. The investigation shows an important state of the art that provides technical solutions to apply on novel architectures based on rigid structural systems and articulated and slip structural systems. The research is useful to produce the current constructive solutions based on these constructive systems.

Abstract:
The increasing trend of global energy demand due to rising population, comfort expectations and living standards has caused a prevalent concern about the state of the supply-demand chain of energy in the upcoming years. Considering that the building sector is responsible for about one-third of the final energy demand and related greenhouse gas emissions, it is important to take actions in order to reduce the energy demand of building sector and consequent release of greenhouse gas emissions [1]. Moreover, energy need of the globe is expected to be doubled by 2050. In this context, the concept called Net Zero Energy Buildings (NZEBs) stands as a promising solution to the problem since it offers energy-efficient and high-performance buildings, and healthy indoor environments. Furthermore, NZEB can significantly cut down the indirect greenhouse gas emissions due to the reduction in energy demand.

Abstract:
Established on peripheral sub-urban area of Sylhet city, Shahjalal University of Science and Technology is a public university well known for its beautiful natural environment and diversified landscape with green hillocks, waterscape, forests and biodiversity. But, the academic buildings of the campus were planned in an introvert way that the common void courts remain disconnected from the outside natural environment. Although designed with positive intention, most of the courts remain unused maximum the time of a year. As the campus natural environment is getting richer day by day and users prefer to spend more time in outside environment, it is high time to integrate nature into the academic learning. This research aims to explore the possibilities of these void courts to be incorporated with the outside natural environment to enhance joyful learning. A combined approach was adopted as research methodology consists of intensive physical survey, literature study, microclimate analysis, questioner surveys among the users, interviewing the field experts and selective national and international case studies. Lastly, a set recommendation has been proposed considering all the perspectives and issues that the research has identified.

Abstract:
With the increased application of High Strength Concrete (HSC) inconstruction and lack of proper guidelines for structural design in India,behavioral study of high strength concrete is an important aspect ofresearch. Research on the behavior of HSC reinforced beams with concretestrength more than 60 MPa has been carried out in the past and is stillcontinuing to understand the structural behavior of HSC beams. Along withthe many benefits of the high strength concrete, the more brittle behavior isof concern which leads to sudden failure. This paper presents the behaviorof reinforced HSC beams in shear with considering the effects of variousfactors like shear reinforcement ratio, longitudinal reinforcement ratio, l/dratio (length to depth ratio), etc. Ten numbers Reinforced Concrete Beamsof various sizes using concrete mix with three different w/c ratios (0.46, 0.26and 0.21) were cast for shear strength assessment. The beams were tested insimply supported condition over two fixed steel pedestals with load rate of0.2 mm/minute in displacement control. Mid-point deflection was measuredusing LVDT. A comparative analysis of theoretical approaches of Eurocode, extension of current IS code up to M90 and the experimental datawas done to understand the behavior of beams. Shear capacities of beamswithout any factors of safety were used to assess the actual capacities andthen was compared with the experimental capacity obtained. Results ofthis study can be used in the design of high strength concrete and will bemore reliable in Indian continent as the regional materials and exposureconditions were considered.

Abstract:
There is a perpetual problem of partial or complete roof collapse withinthe Tamale Metropolis and other parts of Ghana. This has become an issueof grave public concern since this menace affects both public buildingsof all kinds (schools, offices, churches, mosque etc.) as well as domesticbuildings.This research sets out to conduct comprehensive investigations into thenature of roof failures, causes, and effects and then propose remedialactions towards stemming the tide.The study employed the use of roof construction affirmation surveys,questionnaires, interviews and focus group discussions. Relevantinformation synthesized indicates that the roof type, construction materials,building type and environmental conditions are crucial causative factors.Major consequences of roof failures include damage to personal belongingsand exposure to inclement weather conditions, the psychological traumavictims are subjected and pressure on incomes and living conditions as aresult of the cost of repair or replacement of the roofs.It is recommended that expert advice be sought in checking maintenancerequirements of existing roofs in the study area and also during the designand construction of new roofs. Tree planting programmes for this heavilydeforested region should be encouraged. The use of green timber for roofconstruction must be replaced with well-seasoned ones. Proper constructiondetailing and placement openings buildings should be done so that windflow during a windstorm is optimized.
