摘　　要：以杆系结构分析结果为基准,研究了底层不等高的多层框架在水平侧力下采用D值法计算内力反应的近似程度。通过单跨和多跨的底层不等高的多层框架的两个典型算例分析,探讨了误差形成的一般规律及其主要影响因素。On the basis of the results of member finite element analysis, the accuracy of DValue method in structural analysis of frames with uneven height columns in the first story under lateral forces is evaluated. Two typical frames with singlespan and multispans were analyzed. The error resources and dominant factors influencing the accuracy of this method are summarized. 
