某超高层多塔结构性能化设计

Performance-Based Design of a Super High-Rise Multi-Tower Structure

以具体工程为例,对超限高层建筑多塔结构的抗震性能设计进行总结。该工程为体型不规则的超限高层结构,用ETABS和YJK做小震对比分析,并补充小震弹性时程分析,采用等效弹性法对该工程进行性能化设计,采用佳构软件对结构进行动力弹塑性时程分析,评估结构在罕遇地震下的抗震性能。

This article takes a specific project as an example to summarize the seismic performance design of multi-tower structure of an over-limit high-rise buliding.The project is an irregular high-rise structure.This project uses ETABS and YJK for small earthquake comparative analysis,supplements small earthquake elastic time history analysis,and uses the equivalent elastic method to perform performance-based design of the project,and use Jiagou software to conduct dynamic elasto-plastic time history analysis of the structure to evaluate the seismic performance of the structure under rare earthquakes.
