Seismic Behaviors and Analysis for Dual Function Slitted Shear Wall
,-0001,():
A new type of passive controlled RC shear wall, called dual function slitted shear wall (DFW wall), was proposed by the first author. DFW wall is formed by setting connectors in the vertical slits of RC slitted wall. DFW wall can provide larger stiffness and strength than RC slitted wall under small and moderate earthquake, and performs a ductile flexure failure as RC slitted wall with the failure of connectors under severe earthquake. Experimental studies to investigate the seismic behaviors of DFW wall, including seven wall specimens and thirteen connector specimens, were introduced firstly in this paper. Then an analytical model was proposed to calculate the full skeleton load-displacement relation for DFW wall. The analysis results were found agree well with test ones. A dual seismic structure model was used to study the dynamic response of DFW wall using time history analysis method. The experimental research and analysis demonstrated the dual control functions, and showed that DFW wall has better seismic performance than the corresponding slitted shear wall.
