Investigation on cross sheeting thickness and its width in strengthening of steel shear wall under seismic load

The steel shear wall, as a system to resist the lateral loads, buckles when it is vulnerable to the lateral loads applied to the frame before it reaches its ultimate strength. This phenomenon is due to the small thickness of shear wall relative to the adjacent beam and column. Hence, the idea of rei...
