The seismic performance of an H-shaped core buckling-restrained brace (HBRB) is evaluated through detailed finite element analysis. The numerical model is validated against available experimental data and a parametric study is carried out to investigate the effect of influential parameters on the cyclic behavior and failure modes of HBRB. Several design parameters including the yielding length ratio, the constrained length, the presence of stiffeners and their thicknesses, the length of the transition region and the gap size are considered in the parametric investigation. Based on the analysis results reducing the yielding length of HBRB increases its post-yield stiffness and the axial strain and stress of the H-section core. Since buckling of the unconstrained region was observed in HBRBs with insufficient stiffener thickness, an analytical method is proposed for evaluating the sufficiency of stiffeners by estimating the critical buckling load of HBRB as a three-segment stepped compression member.

Coupled Shear Wall

In the last several decades, coupled shear wall have become recognized as efficient lateral load resisting systems for high-rise structures, increasingly. Coupled shear walls give considerable lateral stiffness and strength as well as providing an architecturally practical structural system. In this paper, in order to observe seismic performance of coupled steel plate shear wall, models of previous study was verified, and coupled shear wall with steel plate was carried out with various parametric analysis. Parametric analysis was performed with various width of bay. As a result, model that aspect ratio of steel plate was close to 1 was the most structurally safe.

The self-compacting concrete is described as one of the environment friendly concrete which has several benefits over ordinary concrete. The main advantages of self-compacting concrete are that problem associated with vibration is eliminated. It is a non-segregating concrete that have benefits such as high bond to reinforcing steel, superior strength and durability, improved structural integrity etc. The Glass Fiber reinforced Polymer (GFRP) rebars are preferable alternative to steel rebars for minimizing corrosion problems In this paper, analytical study is carried out to investigate the seismic performance of self-compacting concrete circular columns reinforced with GFRP rebars and are compared with columns reinforced with steel rebars. The main parameters considered for the study are slenderness ratio and confinement techniques. The circular column of slenderness ratio 4, 6, and 8 are considered for the study. The seismic performance is carried out by Push over analysis using ANSYS software.
