骨架式索膜-混凝土组合结构受力性能分析

摘要

通过对某体育场看台结构进行分析，分别建立了整体模型、骨架式索膜结构模型和混凝土结构模型，通过对两种工况下的3个模型的位移和内力My进行分析研究，得到骨架式索膜一混凝土组合结构及其控制作用的水平荷载为风荷载，组合面设计时建议考虑整体模型计算结果进行综合设计。%Through analyzing the stadium stand structure, the paper respectively establishes overall model, skeleton-type cable-membrane struc- ture model, and concrete structure model. By analyzing and studying the displacement and internal force My of 3 models under two working con- ditions, it obtains that horizontal load of skeleton-type cable-membrane-concrete composite structure is wind load, and overall model calculation results should be taken into consideration into comprehensive design in composition design.
