下部支承结构对网架结构受力状态的影响分析

Influence Analysis of Supporting Structures on Structural Responses of Grid Structures

本文回顾对比了网架结构的基本计算方法和混凝土框架-钢网架混合结构常用简化分析方法。结合某办公楼工程实例分别建立上部钢网架结构的单独计算模型和混凝土框架-钢网架结构整体有限元模型进行结构分析,通过对两种计算模型分析结果的比较,分析下部混凝土支承结构对上部网架结构受力状态的影响。

Analysis methods for grid structures and simplified analysis methods for hybrid structures of grid roofs and concrete frames are listed. Taken the specific project of an office building for example, finite element models of the gird structures with and without the supporting structures are built respectively. Comparison between analysis results of the two models verifies the influence of supporting structures on structural responses of upper grid structures.
