| 中文摘要 | 根据汽车炸弹恐怖爆炸的特点,计算了汽车炸弹近地爆炸空气冲击波参数,提出了防爆墙结构等效静载的弹塑性动力计算方法。按该方法设计了一种钢板混凝土装配式防爆墙组合结构,并与有限元数值分析结果进行了比较。结果表明,按该方法设计的防爆墙结构,其设计荷载只有其峰值压力的五分之一,能很好地发挥防爆墙结构塑性变形的特点,具有较大的经济价值。; According to the characteristic explosion of the vehicle bombs,the parameters of air shock wave in the vehicle bombs explosion near the surface are calculated in this paper.The elastic-plastic calculation method of blast resistant wall subject to equivalent loading is established.A type of assembling component structure of reinforced concrete and steel plate for the blast resistant wall is designed by using the method,and computational results are compared with results of the finite element method.Results show that the design loading of blast resistant wall is the fifth peak value pressure of air shock wave and have provided with economic worthiness by using the plastic deformation characteristic of the blast resistant wall.; 国家自然科学基金资助项目(50578082和50678094) |
