结构分析中虚梁设置必须注意的问题

Imaginary beam settings must advert the issue in structural analysis

针对建模时,虚梁的使用可能导致分析结果不符合实际传力情况的问题,利用PKPM,ETABS两种常用结构分析软件分别建立比对模型,通过对模型结果进行分析比较,找出错误产生的原因,最后给出一些利用虚梁导荷建模的建议。

Aiming at in modeling, the use of imaginary beam will cause some problems that could lead to the results of the analysis act against the actual load-transfer situation. In this paper, use PKPM, ETABS two commonly used structural analysis software, respectively to establish the contrastable models. And through analyzing the results of model comparison, find out the causes of error. Finally, give some advices about the use of imaginary modeling beam to transfer load.
