A FINITE ELEMENT MODEL FOR POST-FIRE SEISMIC PERFORMANCE OF STEEL REINFORCED CONCRETE COLUMNS

  • 摘要: 该文建立了型钢混凝土柱温度场计算模型,计算结果与实测结果吻合较好。同时,还提出了型钢混凝土柱过火最高温度场的计算方法,并在考虑型钢与混凝土之间以及钢筋与混凝土之间的界面粘结滑移特性的基础上提出了火灾后型钢混凝土柱抗震性能的有限元计算模型,计算结果与试验结果吻合较好。该文模型可用于型钢混凝土柱火灾后抗震性能的计算与分析。

     

    Abstract: A finite element (FE) model for temperature calculation in steel reinforced concrete (SRC) columns was proposed, and the results of the calculation agree well with those from testing. Then, a calculation method for the highest temperature field of the SRC columns was proposed, based on which a FE model for the post-fire seismic performance of the SRC columns was proposed. In the FE model, the bond-slip properties between steel and concrete and between rebar and concrete are simultaneously considered. It is shown that calculated results agree well with test results, and the FE model can be used to analyze the post-fire seismic performance of SRC columns.
