摘　　要：在强烈地震作用下 ,高耸结构的破坏除了因为水平地震的作用外 ,竖向地震作用的影响也很大。根据撞击原理 ,对高耸结构的竖向地震作用进行了分析计算 ,表明竖向地震作用的大小主要取决于地震烈度和场地土的类别 ;烈度和场地土类别较高时 ,结构的上部有拉力产生 ;烈度和场地土类别越高 ,上部结构的受拉范围和最大拉力越大 ;地基基础和下部的质量越大 ,受拉范围下移。Under the action of intense earthquake,the damages of high building were not only caused by horizontal earthquake action,but also caused by vertical earthquake action.Based on collision theory,this paper analyzed and calculated the vertical earthquake action on high buildings.Which deduced that the magnitude of vertical earthquake action was principally depended on the intensity of earthquake and the sort of seismic site.And when the intensity of earthquake and the sort of seismic site were high,the tension force would occur in the up part of structure.The higher the intensity of earthquake and the sort of seismic site,the larger the tension force and its scope.
