RC框架结构Pushover方法的保证率和适用性研究

以7层钢筋混凝土平面框架结构为例，通过统计分析不同地震烈度、不同场地条件、不同地震分组的平面框架在不同抗震设防水准条件下的Pushover分析性能点的概率分布，探讨Pushover分析方法的保证率和适用性.研究表明，Pushover分析方法是一种静力弹塑性分析方法，不适用于结构弹性抗震性能评估.
Based on a 7-story reinforced concrete plane frame structure, the guarantee rate and suitability of Pushover analysis method were discussed by statistically analyzing the probability distribution of the performance point of the Pushover analysis method of plane frames with different seismic intensities, site conditions and design earthquake groups in various seismic fortification levels. The results show that Pushover analysis method is a static elastic-plastic analysis method, which is not suitable for evaluating the structural elastic seismic behaviour.
