某63米大跨度连体高层结构分析与设计

Analysis and design of a 63-meter long-span conjoined high-rise structure

某双塔连体高层结构,连接体的主要跨度为63 m,与主楼采用刚性连接。针对结构体系不规则超限类型进行分析,对结构体系采用不同的力学模型进行多遇地震作用下弹性分析;完成中震和大震下的性能化设计分析,罕遇地震作用下静力弹塑性分析;依据计算分析结果,提出有效控制安全的抗震设计技术措施等。

The main span of a double-tower connected high-rise structure is about 63m,and they are rigidly connected.This paper analyzes the irregular over-limit types of the structural system,and uses different mechanical models to carry out elastic analysis of the structural system under the action of multiple earthquakes;and completes the performance-based design analysis under the moderate earthquake and major earthquake,and the static elastic-plastic analysis under the major earthquake;according to the calculation and analysis results,the effective measures of seismic design technology are put forward.
