在基于性能的抗震分析中要准确地评价结构的抗震性能需要能准确地预测结构的非线性特性。基于性能的抗震性能评价方法中,目前被广泛应用的有静力弹塑性(Pushover)分析方法。该方法在评价结构整体的非线性响应和结构局部的非线性响应时,需要使用能准确反映结构动力特性的横向荷载模式和能更合理地计算结构的性能点位置的计算方法。本文提出了能合理且高效地评价结构非线性响应的方法,并且与现有的静力和动力弹塑性分析方法计算的整体响应和局部响应结果进行了比较,验证了本文建议方法的准确性和实用性。
In the performance-based seismic analysis to accurately evaluate the seismic performance of the structure need to accurately predict the nonlinear characteristics of the structure. Among the performance-based seismic performance evaluation methods, Pushover analysis is widely used at present. When evaluating the nonlinear response of the whole structure and the local nonlinear response of the structure, this method needs to use the transverse load model which can accurately reflect the dynamic characteristics of the structure and the calculation method to calculate the position of the performance point of the structure more reasonably. In this paper, a method that can evaluate the nonlinear response of structures reasonably and efficiently is proposed and compared with the results of the global response and the local response calculated by the existing static and dynamic elasto-plastic analysis methods. The results show that the proposed method is accurate, Practicality.
