参考美国性能规范ASCE 41,确定结构抗震性能目标和构件可接受准则,并采用静力推覆分析方法对实际结构进行抗震性能评估。分析结果表明,弹塑性层间位移角等性能指标满足规范要求,结构构件均满足各自预期的性能目标,结构基本处于运行控制状态。
Refer to the American Performance Specification ASCE 41 to determine the seismic performance goals of the structure and the acceptable criteria of the component, and to evaluate the seismic performance of the actual structure by static nappe analysis. The analysis results show that the performance indexes such as the displacement angle between elastoplastic and plastic layers meet the requirements of the code, and the structural components meet their respective expected performance targets and the structure is basically in the operational control state.
