Experimental study on seismic performance of coupled steel plate shear wall with slits
摘要
Abstract
To investigate the seismic performance of coupled steel slits shear wall with different cross-sectional dimensions of coupling beams,two one-third scale,four-story specimens with different cross sections were designed and fabricated,and subjected to quasi-static cyclic loading tests.The failure mode and hysteretic behavior of the specimens were inspected,and the influence of the size of the coupling beam on the strength,stiffness,energy dissipation capacity,ductility,column axial force,and coupling beam rotation were explored.The results indicate that the coupled steel plate shear wall with slits possesses stable load-bearing capacity,good ductility,and energy dissipation capabilities,making it an excellent seismic lateral force-resisting system.The failure of the coupling beam will cause a rapid decrease in the lateral load-bearing capacity of the shear wall specimen,so it is necessary to avoid premature failure of the coupling beam.By increasing the dimension of the coupling beam,the initial stiffness,strength,and energy dissipation capacity of the specimen were enhanced.The larger the cross-sectional size of the coupling beam,the smaller the axial force in the frame column,especially for the internal column.The direction of the axial force in the internal column will undergo a reverse,leading to compression along with the external columns,which is beneficial to the stability of the frame column.In addition,the rotation of the coupling beam decreases with the increase in dimension of the coupling beams.However,it is necessary to ensure the reliability of the coupling beam-to-column connection to maintain significant rotational deformation capability.关键词
