摘要
采用结构分析软件SAP2000对某超高层钢管混凝土框架-核心筒结构进行线性和非线性整体稳定分析。分析结果表明,该超高层结构具有较好的整体稳定性能。基于整体稳定分析结果,对结构中底部跨层柱的计算长度系数进行计算。
SAP 2000 software was used to analyse the whole stability of a high-rise CFT frame-tube structure, including linear analysis and nonlinear analysis. The results show that the structure has good whole stability. Based on the whole stability analysis results, the calculated length coefficient of cross-layer columns in the bottom district of structure was determined.
