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 DValue method in structural analysis of frames with uneven height columns in the first story under lateral forces is evaluated. Two typical frames with singlespan and multispans were analyzed. The error resources and dominant factors influencing the accuracy of this method are summarized.
