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。
The paper establishes the temperature field calculation model of SRC column, and the calculated results are in good agreement with the measured results. At the same time, the calculation method of the maximum temperature field of steel reinforced concrete columns is put forward. Based on the consideration of the interfacial adhesion and slippage between steel and concrete and between steel bar and concrete, the seismic performance of post-fire steel reinforced concrete columns Finite element calculation model, the calculated results are in good agreement with the experimental results. The model can be used to calculate and analyze the seismic behavior of steel reinforced concrete columns after fire.
