Abstract:Nonlinear finite element analysis under monotonic load of short-leg shear wall,with or without concealed column,was carried out by ANSYS software,and the analysis results were compared between bearing capacity,ductility and failure characteristics.The influence of ratio of axial compression and concrete grade on mechanics characteristic parameter and internal force distribution of short-leg wall with concealed column were summarized,which could provide valuable theoretical and experimental references for section design.Seismic performance of the wall could be enhanced effectively by the increase of axial compression ratio and level of concrete wall.However,exorbitant axial compression ratio and level of concrete wall will significantly decrease the ductility.
