| 摘要: |
| 为解决结构抗震性能分析结果会因地震动记录选择上的差异产生较大变异性问题,采用非概率凸集模型来考虑地震作用的不确定性,以结构最大层间位移角作为抗震性能指标,通过能力谱方法对一钢筋混凝土框架结构进行非概率性抗震性能评估,与基于概率随机模型的抗震性能分析结果进行比较.结果表明,采用非概率凸集模型进行结构抗震性能分析,在减少变异性的同时,还具有一定的合理性和适用性. |

| Abstract: |
| Convex model was used to consider the uncertainty of earthquake in this paper to solve the problem that the selection of different ground motion records will result in great variability in structural seismic performance analysis. Taking the inter-story displacement angle as seismic performance index, non-probabilistic seismic performance of a reinforced concrete frame was assessed under the motivation of rare earthquake by the capability spectrum analysis method. Then the results were compared with probabilistic seismic performance based on the probabilistic random model. By comparison and analysis, it shows that the evaluation of structural seismic performance based on convex model not only reduces the variability, but also is reasonable and applicable to some extent. |
