摘　　要：通过弹塑性推覆方法分析结构进入塑性后强度中心的偏离现象,研究质量分布对强度中心分离程度的影响.在同一规则结构上,按两种不同的质量分布,分别对结构进行推覆分析,比较两种情况强度中心的偏离,初步显示强度中心偏离程度基本一致.By elasto-plastic pushover method, the detachment about the center of strength is analyzed. The influences of the structural different mass distribution on the detachment are researched. The pushover analysis of the two different mass distributions based on the same regular structure was carried out, and the detachments about the center of strength from the two different mass distributions are compared. It shows that the detachments about the center of strength in the two cases are nearly the same.
