摘要
本文在火灾后钢筋与混凝土应力-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压弯构件恢复力骨架曲线特征参数的统计公式,从而为火灾后剪切型钢筋混凝土结构的地震反应分析及其抗震加固奠定了基础。
Based on the test results of σ-ε curves of concrete and steel and by using numerical methods, regression formulas for parameters of hysteretic curve of R. C. compression -flexure members after fire have been given in this paper,and it provides a foundation for earthquake response analysis and strengthening of earthquake capacity of shear R. C. structures after fire.
