混凝土框架结构支撑网架屋面体系的结构设计与分析

Structural Design and Analysis of Grid Roofing Structure Bearing on Concrete Frame Structure

文章针对混凝土框架结构支撑网架屋面结构体系,以一上部采用网架结构、下部采用混凝土框架柱支承结构的工程为例,通过两种不同软件进行建模计算,对计算结果进行了对比分析,得出两者动力特性相差较大,而单柱荷载相差不多。同时针对建模过程中容易忽略的问题提出建议,供设计人员参考。

Focus on grid roofing structure bearing on concrete frame columns, this paper based on an engineering project which has grid roofing structure bearing on concrete frame columns, two methods to build model were presented to analyze the difference between these two modeling,big discrepancy on dynamic property while little axial force of single column between these two models is put up.Meanwhile, several strengthening measures were presented to reference the practical engineering.
