Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

Steel plate shear walls (SPSWs) have advantages such as high elastic stiffness, stable hysteresis behavior, energy absorption capacity, and decent ductility. However, one of the main drawbacks SPSWs is their buckling under lateral loading. To address this issue, a simple practical solution in form using trapezoidal moment connection (PMC) narrow gap between infill columns presented. The PMC wil...

There is a possibility of increasing structural damage in the sequential earthquake compared to main according past earthquakes. This study investigates effects seismic sequence on behavior and increased response reinforced concrete frames (RCF) with/without steel plate shear walls (SPSW). Four systems 4, 8, 12, 24 story, which represent low-, mid-, high-rise structures, are designed subjected ...

Many studies on structural topology optimization of steel plate shear walls have been conducted. However, research using the bidirectional evolutionary method is limited. Accordingly, this study optimized stiffening effect (SPSWs) based method. A finite element model SPSW was established Abaqus software through “sandwich” modeling An region expanded into two regions. As targets, SPSWs with diff...

The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...

As a new alternative design, plate-reinforced composite (PRC) coupling beam achieves enhanced strength and ductility by embedding a vertical steel plate into a conventionally reinforced concrete (RC) coupling beam. Based on a nonlinear finite element model developed in the authors' previous study, a parametric study presented in this paper has been carried out to investigate the influence of se...

damages due to northridge and kobe earthquakes were expressive of considerable effects of vertical components of earthquakes compared to the horizontal ones. on the other hand, thin steel plate shear wall is one of the newest resistant systems which until now it`s behavior haven’t been investigated under vertical component of earthquake. therefore, in this article, effects of vertical component...

This paper describes the prototype design, specimen design, experimental setup, and experimental results of three light-gauge steel plate shear wall concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity, and emphasis is placed on minimizing their impact on the existing framing. Three single-story test spe...
