Corrugated Steel Plate Shear Wall with Opening and Stiffener at Opening
Jeena James, Aswathy S Kumar
The greater increase in the number of tall buildings the effect of lateral loads like earthquake forces creates greater damage to the entire structure. Steel plate shears wall system that is integrated into the frame of a structure that serves to accept and dissipate shearing forces that may be associated with seismic activity. The system consists of boundary elements of horizontal and vertical steel beams and thin web steel plate. The web plate may be flat or corrugated. Web plate remove burden of excessive lateral force generated by an earthquake from the system frame and the overall building frame. Openings may need to be created within the steel corrugated infill plate to accommodate for architectural purposes, passing utilities, and structural reasons. The ultimate strength of shear wall was varying when corrugation angle of panel changed. The strength of shear wall decreases when cutout provided at the center.The strength can be increased by providing stiffeners around the cutout. This paper conducting the study for selecting corrugated steel plate shear wall with higher load carrying capacity from out of these different angles (0, 30, 60, 90) of corrugation. Corrugation was provided with respect to the x axis.Study was also conduct by providing cutout at the center and stiffener around cutout of corrugated shear wall which carrying greater load carrying capacity.
