摘　　要：首先通过有限元软件计算出两端固定的钢骨混凝土梁在冲击荷载下的残余位移,然后基于刚塑性理论对残余位移进行公式拟合,最后通过公式值与模拟值的对比验证拟合公式的有效性。研究结果表明:拟合公式精度较高,可用于快速计算冲击荷载下构件的残余位移。This paper first computes the residual displacement of SRC(Steel Reinforced Concrete)beam fixed at both ends by finite element software,then fits the formula of residual displacement based on rigid plastic theory,finally verifies the validity of formula by the comparision between simulated and fitted value.The result indicates that the formula can be used to calculate the residual displacement of beam for its higher accuracy.

关 键 词：刚塑性理论 公式拟合 残余位移
