摘要
高层建筑在进行结构分析之前应首先确定结构嵌固端所在的位置。本文采用M法模拟回填土对于高层建筑地下室的约束,并运用有限元分析软件MIDAS GEN对结构进行静力弹塑性分析。研究得出,一面开敞的非全埋地下室嵌固端可选在地下室顶板处,并在一定范围内可通过增大连梁及框架梁刚度与增加底层竖向构件配筋的方法来延迟地下一层塑性铰出现的时间,使结构趋于安全。
In making structural analysis of tall-buildings, the position of structures＇fixings must be decided first. In this study, we adopted M method to simulate backfillg constraint on basements of tall-buildings, and used MI-DAS GEN to make static elastoplastic analysis of the structures. We found that fixings of one side open semi-basements can be positioned on the roof. Moreover, it was found that to increase the rigidity of coupling and frame beams, as well as to increase the amount of component reinforcement both delays the appearance of plastic hinges and consequently enhance the safety of the structures.
