摘要
本文在火灾后钢筋与混凝土应力一应变关系试验结果的基础上,通过大量数值计算,给出了火灾后钢筋混凝土构件的截面夸矩一曲率恢复力骨架曲线特征参数的统计公式,为利用杆系模型进行火灾后钢筋混凝土结构的地震反应分析并进行抗震加固奠定了某础。
Based on the test results of concrete and steel σ-ε curves and calculations, this paper puts forward the rcgression formulas for parameters of M- φ skeleton curve of R.C. members after fire, which provide a foundation for earthquakc response analysis and seismic retrofit of R.C. structures after fire.
