| 摘 要： | 增量动力分析(IDA)方法是一种基于弹塑性时程分析结果的参数分析方法,能够给出任一性能水准下的结构性能,反映结构在未来可能发生的一系列强震下变化的动态特性、结构的极限变形能力等抗震性能.采用IDA方法对9个不同结构特性的高层钢框架-混凝土核心筒混合结构展开分析,提出了高层混合结构的四个性能水准,并给出了相应的最大层间位移角范围,以作为基于性能设计抗震设计的控制指标.

| Abstract: | Incremental dynamic analysis(IDA) is a parametric analysis method based on the results of elasto-plastic dynamic analysis.It can be used to analysis the structural behavior under different performance levels.The seismic performance such as deformation capacity and dynamic characteristics can also be obtained by IDA method.Nine hybrid structures with different structural characteristics were analyzed by IDA method.Based on the analysis,four performance levels and the range of maximum story drift of each leve... |
