不同倒塌判定准则对评价RC框架结构抗倒塌能力的影响
|
摘要
合理评价建筑结构抗倒塌能力是综合评价结构抗震性能和进行抗倒塌设计的前提与基础。由于模拟结构倒塌过程的复杂性,通常是以间接的方式(倒塌判定准则)判断结构是否发生倒塌。倒塌判定准则的重要性不言而喻。根据试验与数值分析相结合的手段,分析4种常用的倒塌判定准则判断结构倒塌的合理性;基于IDA的结构抗倒塌易损性分析方法,定量分析各倒塌判定准则对确定RC框架结构抗倒塌能力的影响,并根据分析结果提出有关建议。
Reasonably evaluating the collapse-resistant capacity of building structures is the premise and foundation of structure seismic performance assessment and collapse-resistant design. Because of the complexity of structure collapse simulation, collapse criteria, an indirect way, is usually used to judge whether the structure collapse or not. The collapse criteria play an important role in evaluating structure collapse safety. The rationality of four collapse criteria were evaluated with experiment and numerical analysis. And then the effect of these criteria on determine the collapse-resistant capacity of RC frames was quantitatively evaluated using a collapse fragility analysis based on an incremental dynamic analysis(IDA). Some suggestions are proposed to select the collapse criteria.
