STUDY OF UNIDIRECTIONAL WALL FRAMES' INFLUENCE ON THE SEISMIC PERFORMANCE OF SHEAR WALL STRUCTURE

Based on the internal force and deformation analysis method of frame-shear wall structure，the equation of stiffness characteristic coefficient of wall frame-shear wall structure was derived to analyze the deformation characteristics of structures with different wall frames ratio and height of house． The results of theoretical analysis was verified by elastic response spectrum calculation． Through static elasto-plastic analysis，the seismic performance of structures were evaluated by interlayer displacement angle and plastic hinge development process． The research results show that the wall frames bring adverse effects on the structural seismic performance，so the different design regulations such as strengthening of member and control of structure height should be implemented according to the overturning moment proportion of wall frames．
