摘要
某外框不封闭框架-核心筒结构,为高度超B级高度的超限高层建筑。介绍了结构体系和性能目标的选取,对结构进行了小震弹性及时程分析、中震分析、大震弹塑性时程分析。计算结果表明,结构体系合理,可以实现预定的性能目标,具有较好的抗震性能。
The frame-tube structure with unclosed outer frame is a super tall building with a height exceeding B level. The selection of structural system and performance target was introduced,and the elastic analysis and time history analysis of small earthquake was also conducted,medium earthquake analysis and elasto-plastic time history analysis of large earthquakes. The calculation results show that the structure system is reasonable and can realize the predetermined performance target and has better seismic performance.
