摘　　要：总结和分析了钢筋混凝土梁在低速冲击下的局部与整体变形和破坏特征,考虑冲击体头部形状影响的局部效应,研究以弯曲理论为基础,考虑钢筋混凝土梁的裂缝形成(准弹性阶段)和破坏(塑性阶段)的计算方法,通过建立简化计算模型,得出了钢筋混凝土梁在低速冲击下的计算公式。The characteristics of local and total deformation of reinforced concrete beam under low velocity impact were systematically summarized and analyzed in this paper. The calculation method of quasi-elastic and plastic processes for reinforced concrete beams was presented considering the local effect of projectile according to theory of bending. The calculation formulas of reinforced concrete beams under low velocity impact were obtained by establishing the simplified calculation models.
