摘要
目前基于性能的抗震设计研究方兴未艾,其中pushover分析方法作为目前主要的可供操作的抗震设计方法得到广泛的研究。在pushover分析方法中,其中一个关键的问题就是侧向荷载分布方式的确定,因此对各种不同荷载分布方式作综合的分析与比较研究非常有必要。总结了前人所提出的各种不同的侧向荷载分布方式,同时提出一种新的瞬时适应性的侧向荷载分布方式,通过两个实例分析比较了各种不同荷载分布方式的适用范围、有效性及其对结构弹塑性分析结果的影响。
The research of the performance-based seismic design is now in the ascendant, and the pushover analysis as one main analytical method of the performance-based seismic design has been studied extensively. The lateral load pattern is one key problem of the pushover analysis, so the analysis and comparison of many different lateral load patterns are necessary. In this paper, many different lateral load patterns derived by former scholars are summarized, and at the same time, one new instantaneous adaptive lateral load pattern is developed. Finally, the applied scope, the validity and the effect of many different lateral load patterns used in the structural plastic analysis are compared through the analysis of two examples.
