Cyclic Loading Response of Smart Composite Corrugated Steel Plate Shear Walls

Abstract

Abstract Composite shear wall contains concrete, reinforcements and plate with and without steel columns at the ends of shear wall. Steel plate within composite wall either straight or corrugate plate that connected with concrete by shear stud connectors to working as unity. A smart structure such as smart composite shear walls is the technology that adopted and constructed in the latest building and structure control system. This research presents a finite element model using ABAQUS software to model the corrugated steel plate reinforced concrete composite shear walls. The proposed models were validated with experimental data in literature -used to study the effects of the cyclic loading on the behavior composite shear wall. Composite wall panel considered in present study consisting of reinforced concrete shear wall with middle corrugated steel plate within steel frame with and without gap. Nonlinear analysis adapted in study to check out the full performance of composite wall under the effects of cyclic loadings. Deformations, drifts and energy dissipations investigated throughout analysis. Several parameters are adopted such as plate thickness, stud shear connectors spacing and the effect of gap between concrete panels and steel frame. Based on the analysis results, provide gap that separate the concrete panels and the steel frame (smart structural solution) is to make the concrete panel behave alone without confinement of steel frame under low load so that the steel plate carrying of the applied loadings. From the analytical results obtained from the study the effect of gap on the overall behavior of composite corrugated steel plate shear walls. When the loading increase up to limit produce displacement that make the IV concrete panels and the steel frame close. Based on the models with different gaps, increasing the gap between concrete panel and surrounding steel frame have a great effect on the strength and deformation of whole structural system. Displacement decrease in case of the gap between concrete and steel frame increase at selected time because of the top displacement influenced by the gap so that increase in gap need to high loadings to close. Energy dissipation is higher in case the gap increase such. Higher ultimate strength and stiffness in case of gap 32 mm that gave best results. The presences of gap make no interaction could occur between the concrete panel and the steel frame.
