摘要
利用结构抗震验算的思路，计算在大震作用下楼房的弹塑性变形，进而确定结构薄弱层，然后根据震害等级与结构层间相对变形的统计关系，确定房屋的破坏状态。
By using the thought of structure earthquake resistance checking computations,the authors have calculated the elastic-plastic deformation in the multi-floor ferroconcrete frame buildings in a strong earthquake,and determined weaker layer and destructive state of buildings according to the statistical relationship between the earthquake disaster grade and the layer's relative deformation.
