Details
The behavior of composite walls with flat, corrugated, or profiled steel plates on both sides connected with shear connectors has already been studied under combined constant axial compression load and cyclic lateral load. It is proposed to use the traditional composite profiled deck slab with suitable modification as a shear wall. The profiled steel deck sheets have indents to grip the concrete, and the casting of slabs can be done in the horizontal position. Transport and lifting can also be done in the same position, with the sheet acting in tension. Thus, confining reinforcement needs to be provided only on one side. The steel Sheet will act as horizontal and vertical steel; there is no need to provide confining reinforcements for that side of the composite shear wall.
It is proposed to investigate the behavior of steel concrete composite (SCC) shear walls with a one-side profile sheet under combined constant axial and cyclic lateral load using experiment and Finite element analysis (FEA). The seismic behaviors, including failure modes, strength, hysteretic curves, stiffness degradation, and energy dissipation, have been analyzed and compared. FEA Results show that the seismic performance of SCCS with a one-sided profiled sheet was in between conventional RC Shear wall and SCC Shear wall with both-sided profiled sheets. Therefore, using profiled sheets enhances the seismic performance compared to conventional RC Shear walls. It is expected that these walls can be used as load-bearing walls & can take significant seismic loads. Suitable guidelines for design will be proposed as part of the study.
