Seismic Performance of C-PSW

چکیده مقاله

The study also shows that design axial forces and moments in the boundary columns designed according to capacity design concepts are in good agreement with those of the nonlinear seismic analyses. A series of C-PSWs with different geometry are designed and analysed to evaluate the current period formula in building codes. It is observed that the current code predicts periods that are generally shorter than the periods obtained from finite element analysis. An improved simple formula for estimating the fundamental period of C-PSW is developed by regression analysis of the period data obtained from analysis of the selected C-PSWs. Finally, two equations for determining shear stud spacing and thickness of reinforced concrete panel for the C-PSWs are proposed.The study also shows that design axial forces and moments in the boundary columns designed according to capacity design concepts are in good agreement with those of the nonlinear seismic analyses.
