There are a number of factors that typically influence the selection of a structural system including code, cost, construction schedule and site constraints. As sustainability increasingly becomes an important goal during the design process, the role of structure in the overall sustainability of a building will need to be considered in terms of embodied energy, building longevity, reuse and dec...
Investigations were carried out to study the effects of heat treatment on the mechanical properties of rolled medium carbon steel. The steel was heated to the austenizing temperature of 830C and water quenched; It was reheated to the ferrite – austenite two phase region at a temperature of 745C below the effective Ac3 point. The steel was then rapidly quenched in water and tempered at 480C to p...
High reliability and operational safety are most important requirements of aerospace products. Structural Safety (Reliability) assessment techniques help to achieve safe designs and also identify effect of uncertainty occur in structural systems of aerospace products. In general the structural safety is evaluated using various statistical methods like Mean Value and Moment Methods. Currently se...
This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...
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...
