摘要：通过建立典型钢框架的连续倒塌分析数值模型，使用拉丁超立方抽样方法抽取随机样本进行可靠度分析，考虑结构参数的不确定性影响，确定完好结构在地震作用下发生局部损坏的概率。以大震作用下可靠度指标最小的构件作为结构的失效构件，基于整体可靠度方法，采用拆除构件法对失效构件进行拆除并施加地震荷载进行分析，得到不同失效模式下受损结构发生连续倒塌条件可靠度指标和失效概率。最后结合失效构件的失效概率，研究结构在地震作用下的连续倒塌全概率可靠度。研究表明，运用可靠度理论对钢框架结构进行连续倒塌可靠度分析，可以直观地得到地震作用下钢框架结构发生连续倒塌的概率，为准确评价钢框架结构在地震作用下的抗连续倒塌能力提供依据。

Vertical progressive collapse reliability analysis of steel frame structure under earthquake
Abstract: By establishing a numerical model for progressive collapse analysis of a typical steel frame, random samples were taken by Latin hypercube sampling method for reliability analysis.Considering the influence of uncertainty of structural parameters, the probability of local damage of the intact structure under the action of earthquake was determined. Taking the component with the smallest reliability index under the action of a large earthquake as the failed component of the structure. Based on the overall reliability method, the failed component was removed by the dismantled component method and the seismic load was applied to analyze it. The progressive collapse condition reliability index and failure probability of the damaged structure under different failure modes were obtained. Finally, based on the failure probability of the failed component, the full probability reliability of the structure's progressive collapse under the action of earthquake was studied. The research shows that the reliability analysis of the progressive collapse of the steel frame structure by the reliability theory can intuitively obtain the probability of the progressive collapse of the steel frame structure under the action of earthquake, providing a basis for accurately assessing the progressive collapse resistance of the steel frame structure under the action of earthquake.
Keywords: steel frame structure; progressive collapse reliability; dismantled component method; Latin hypercube sampling; failure mode
