本文介绍了某大厦采用主次框支梁转换结构。从结构整体计算及推覆分析等方面进行了结构抗震计算,计算结果表明该结构整体计算指标满足规范要求。阐述了针对转换层楼板局部错位的转换梁,采用了实体单元对结构整体进行了有限元分析。对复杂框支转换结构的计算设计进行了探讨。
This article describes the use of a major building frame beam conversion structure. The structural seismic calculation is carried out from the aspects of overall structure calculation and nappe analysis, and the calculation results show that the overall calculation index of the structure meets the requirements of the code. The conversion beam with partial dislocation on the floor of conversion floor is expounded, and the solid element is used to analyze the whole structure. The calculation and design of complex box-branch structure is discussed.
