某超限高层的特大跨度连体结构的受力性能分析

Analysis of Structure and Mechanical Properties of Siamese Long-span and High-Rise Structures

某工程的大跨度连体结构,根据工程量对比,选取经济的连体桁架布置方案,并采用有限元分析软件,分析大跨度连体结构在设防地震、罕遇地震作用下内力,并分析连体结构进行温度应力及楼板舒适度分析,分析结果表明,本工程的连体结构的受力和变形均能满足要求,连体结构安全可行。

According to the comparison of the quantities of a large-span siamese structure of a project,the economic siamese truss layout scheme is selected.And the finite element analysis software is used to analyze the internal force of the long-span siamese structure under the action of fortification earthquake and rare earthquake,the heat stress and comfort of the siamese structural.The results shows that the capacity stability of the structure and deformation can meet the requirements,the structure is safe and feasible.
