In this paper, the effect of elliptical shape openings was numerically compared to the case when circular openings were used in the steel panel shear walls. At first, the finite element model in ABAQUS was calibrated by experimental results, obtained from previous studies. Then, three steel shear panels with different sizes of elliptical openings were analyzed under cyclic loads, and the result...

Steel plate shear walls (SPSW) have been used as the primary lateral force resisting system in buildings. Extensive analytical studies on steel plate shear walls in the United States, Canada, Taiwan and other countries have already validated the simple analytical model known as strip model to predict the monotonic behavior of this kind of structural system. However, more research is still neede...

Abstract – In this study, the static analysis of a multi-bay coupled shear wall on an elastic foundation, having any number of stiffening beams is studied using the continuous connection method (CCM). The shear wall is considered to be made up of a finite number of sections in the vertical direction, with or without stiffening beams between each pair of consecutive sections. This method of anal...

Steel coupling beam (SCB) is a substantial member of the hybrid coupled walls system. When are linked by SCB rather than conventionally reinforced or diagonally beams, system’s strength and energy dissipation capacities greatly enhanced. A corrugated web may be used in instead flat to improve these characteristics even more. This paper presents an experimental numerical investigation shear-carr...

In order to quantitatively evaluate the shear-bearing capacity of shear connectors of square concrete filled steel tube (CFST), push-out tests on 14 square CFSTs with shear connectors have been carried out. Among the 14 CFSTs, there are 13 specimens with steel plate connectors and one specimen with steel bar connectors. The following factors are investigated to figure out their influences on th...

Frame structures equipped with steel plate shear walls (SPSWs) have been widely used in high-rise buildings due to their good seismic performance. In this study, the strip model and combined were analyze performance of SPSWs. Furthermore, an improved genetic algorithm (IGA) was established optimize frame for 5, 10, 20 stories. For each layer, layout optimization conducted determine best configu...
