摘　　要：文中给出了层状结构竖向刚心位置、考虑三维地震波同时作用下的竖向构件轴力的计算公式,并结合竖向构件的P-△曲线,为基础滑移隔震结构纵波参与下的多维地震时程反应计算打开了思路,通过工程案例的计算机仿真发现了一些此类结构的多维地震反应规律及特性,丰富了此类结构的研究方法及途径。The vertical stiffness center position of the layered structure and formula to calculate the vertical component of axial force under the action of three dimensional seismic waves at the same time are given .Combined with the vertical component load dis-placement curve , how to calculate the multi -dimensional seismic time history response under longitudinal wave acting on building structure with sliding base isolation is discussed .Through simulation, some law and characteristics of such structures under multi -di-mensional seismic response are found .
