爆炸荷载冲击作用引起的钢筋混凝土柱破坏，会导致结构的连续性坍塌。文中以数值模拟的方法，分析了钢筋混凝土柱在爆炸荷载作用下的动力响应。以建立的钢筋混凝土柱的三维实体模型为研究对象，利用混凝土材料的脆性损伤模型，分析了折合距离不同时钢筋混凝土柱的侧向位移和失效情况，从而得知，随着折合距离的增大侧向位移将逐渐减小。对于钢筋混凝土柱的设计与防护该研究成果具有一定实际意义。

The damage of reinforced concrete column caused by blast loading will lead the structural to progressive collapse. The dynamic response of reinforced concrete column is analyzed by numerical simulation. By using the brittle damage model to the concrete material the three-dimensional solid model of the reinforced concrete column is established. The analysis shows that the lateral displacement will be reduced with the increasing of the scaled distance. The result is valuable for the designing and protecting of the reinforced concrete column.
