摘　　要：通过多点加载试验模拟侧向抗爆炸冲击的性能,研究分析在不同轴压比作用影响下钢筋混凝土柱的破坏过程、破坏形态及峰值荷载。实验结果表明:在侧向爆炸冲击荷载作用下钢筋混凝土柱可能发生剪切和弯曲两种破坏;轴压比的增大使得柱的峰值荷载与侧向位移增加。This paper is aimed at studying and analyzing the damage process of reinforced concrete columns under the influences of different axial compression ratio, damage forms and the Peak value loading through the multi-point loading test simulating the load function to Resist lateral Blast Loading. The results show that there are two kinds of failure types for the reinforced concrete column. The increasing of axial com- pression ratio is accompanied by the increasing of peak value loading and lateral displacement.
