基于破坏准则的钢筋混凝土结构抗倒塌研究进展

Research Progress of Seismic Collapse Resistance of Reinforced Concrete Structures Based on Damage Criteria

为了进一步研究钢筋混凝土结构抗倒塌性能,全面总结了各国钢筋混凝土结构抗倒塌性能试验研究与理论分析的现状,重点介绍了抗震结构破坏准则在建筑结构抗地震倒塌研究中的应用情况;在归纳总结的基础上,指出了基于破坏准则的钢筋混凝土框架结构抗地震倒塌研究存在的问题,建议应在构件破坏准则的基础上确定钢筋混凝土框架结构的倒塌准则和损伤评估指标。研究成果为钢筋混凝土结构抗地震倒塌的定量设计及计算分析提供了理论依据。

In order to further study the seismic collapse resistance of reinforced concrete structures,a summary of existing experimental investigation and theoretical analysis of seismic collapse resistance of building structures at home and abroad was presented.The state-of-the-art of studies on damage criterion of earthquake resistant structures for the collapse analysis was analyzed emphatically.Based on the summary of previous research,the existing problems of seismic collapse resistance of reinforced concrete frame structures based on damage criteria were addressed and pointed out for further study.That collapse criteria and damage assessment indexes of reinforced concrete frame structures should be determined based on member damage criteria were suggested.The research results can serve as a theoretical basis for further calculation analysis and quantitative design on seismic collapse resistance of reinforced concrete structures.
