地震后钢筋混凝土柱的抗火性能研究

摘要: 为分析震后火灾环境下钢筋混凝土柱的反应，根据柱在实际地震作用下的柱顶位移响应进行加载，模拟地震作用,在ISO834标准火灾作用下研究地震后受损混凝土柱的耐火极限。希望能对钢筋混凝土结构抗火设计提供一定的参考依据。

Experimental research on fire resistance of reinforced concrete columns after Seismic damage

Abstract: In order to analyze response of reinforced concrete columns under secondary fire after the earthquake.According to the actual displacement response of the entablature under earthquake to load application and simulated the seismic action.Observing the fire endurance of the damaged columns under ISO834. Hope it can provide some reference materials for fire resistance design of reinforced concrete.

Keywords: reinforced concrete columns;earthquake damage;fire temperature test;fire endurance
