Steel–concrete composite shear wall offers a favourable lateral strength and deformation ductility for seismic applications while significantly shortening the project schedule through eliminating use of formworks taking advantage modular construction methodology. This paper presents fibre-based modelling technique simulation cyclic nonlinear response walls by existing reinforced concrete steel ...

Currently, the steel plate shear wall (SPSW) is commonly used in high-rise buildings as a lateral load-resisting system due to its several advantages such lightweight and high ductility strength. The SPSW consists of two main parts, i.e., boundary frame infill plate, which are connected by welding. objective this work study effect weld separation on seismic behavior SPSWs. A numerical method wa...

Thin perforated Steel Plate Shear (SPS) Walls are among the most common types of energy dissipating systems. The applied holes reduce the shear strength of the plate and allow to decrease the profile size of the members at the boundary of the panel when these systems are used in the typical design of structures. On the other hand, the different fracture locations of these panels are visible whe...

Timber platform-frame shear walls are characterized by high ductility and diffuse energy dissipation but limited in-plane shear resistance. A novel lightweight constructive system composed of steel columns braced with oriented strand board (OSB) panels was conceived and tested. Preliminary laboratory tests were performed to study the OSB-to-column connections with self-drilling screws. Then, th...

The corrugated steel plate shear wall (CoSPSW) is a new type of wall, in which plates instead flat are adopted. lateral stiffness and buckling capacity the system could be significantly enhanced, then, under gravity loads would mitigated. This paper presents study on probabilistic assessment seismic performance vulnerability CoSPSWs using fragility functions. damage states corresponding repair ...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

Modeling Steel Plate Shear Wall (SPSW) behavior can be computationally demanding. This is especially true when high-fidelity modeling carried out via shell or 3D solid elements. It has been shown that SPSW captured with adequate accuracy through the strip method nonlinear truss elements idealization. The widely accepted and reliable analysis platform, OpenSees, requires text-based input (.tcl) ...

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...
