摘　　要：为探析盒式筒中筒结构内筒剪力墙在罕遇地震下的塑性损伤情况,采用ABAQUS软件对某盒式筒中筒结构进行了弹塑性时程分析,从内筒剪力墙受拉损伤、受压损伤的角度,探究该体系的抗震性能。研究表明:剪力墙连梁增强了结构耗能能力,起到了抗震设防第一防线的作用;设计时应注意剪力墙刚度与连梁刚度的相对大小,避免连梁刚度太大引起的区段墙体地震力集中;结构底部剪力墙塑性损伤最为严重,设计时应适当提高此区段墙厚和配筋。In order to investigate the damage of the shear wall of reinforced concrete space- grid box- tube structure under severe earthquake,using abaqus software,research on elastic-plastic time- history analysis of reinforced concrete space- grid box- tube structure. Then,from the Angle of the tensile damage and compression damage of the shear wall,the seismic performance of shear wall is good. Research shows that： the coupling beams which enhance shear wall structure energy consumption ability are the effect of the seismic fortification first line; When the system is designed,the shear wall stiffness and the relative size of the coupling beam stiffness should be paid attention,avoiding even the coupling beam stiffness is too big; The plastic damage of the shear wall of the bottom of the structure the is most serious.When the system is designed,we should be appropriate to improve the thickness and reinforcement of the wall.
