cast connections. ABSTRACT: Diagonal bracings are extremely popular elements for lateral load resistance in steel-framed buildings. In turn, the most common shape used for bracing members is the hollow structural section. While the design of such members is straight-forward, the design of gusset-plate connections at the member ends is controversial. This paper reviews the current ‘state-of-the-...
According to the deformation and movement requirements of the FAST reflector, a multipurpose analysis, including the load-bearing behavior, deformation, construction costs of the reflector supporting structure and its model, is presented in this paper. The advantages and disadvantages of steel and aluminum alloy structures are also discussed and compared through detailed design calculations und...
The paper presents work on low-cost and sustainable alternative building materials having advantages on areas such as India where concrete or steel housing is expensive. The project addresses the challenges and stereotypes of using these materials as a structural component for low-cost housing and their same capacity for adaptation to the broad spectrum of factors—physical, ecological, social, ...
During the last two decades, investigations on the dynamic properties of structural elements have been the subject of numerous research works. The primary reason for this is the awareness and interest in using dynamic testing techniques for the purposes of health monitoring and damage detection for engineering structures. The dynamic properties of any structural element are governed by the rela...
In recent years, there has been increased discussion of the strength of vehicle roofs in rollover crashes. NHTSA recently revised the federal roof strength requirement and the IIHS has published an even more stringent roof strength goal. While working to increase roof strength, automakers are also working to reduce vehicle mass for improved fuel economy and other benefits. Developing technology...
The filling of thin-walled steel tubes with quartz sand can help to prevent the premature buckling of the steel tube at a low cost. During an impact, the internal stress of the quartz sand-filled steel tube column is subjected to not only axial force but also lateral confining force, resulting in complicated internal stress. A suitable sensor for monitoring the internal stress of such a structu...
This study investigates the seismic behavior of deconstructable composite steel/concrete floor systems consisting of precast concrete planks and deconstructable clamping connections attaching the planks to the steel floor beams. The system is proposed to promote sustainable design of composite steel/concrete floor systems in steel buildings via reuse of the structural steel and concrete compone...
Steel has remained the most crucial of all structural materials. However, the steel production processes have changed over the years. Currently, due to the tendency of eliminating high energy consuming technologies, in both the international and domestic steel industry, liquid steel is manufactured in two basic aggregates: oxygen-blown converters and electric arc furnaces 1 . The development of...
