摘　　要：根据结构力学的原理和方法,提出了一种火灾下带轴向约束的钢筋混凝土构件轴向内力的实用计算方法.通过对带轴向约束的钢筋混凝土柱的高温内力分析,并与前人试验结果进行对比,初步验证了该方法的可行性.Based on the philosophy of structural mechanics, a practical approach is developed for determining axially internal forces in reinforced concrete member with axial restrain subjected to fire. A reinforced concrete column with axial restrain is selected for fire response analysis. By comparing the simulation results with the test results given by former researchers, it demonstrated that the approach proposed in this paper is feasible.
