钢筋混凝土柱在冲击载荷下崩落响应分析

Analysis of Caving Response of Reinforced Concrete Column Under Impact Load

对混凝土柱在冲击载荷下所产生的崩落现象进行分析,提出了冲击载荷下混凝土柱崩落响应的分析方法,利用一维应力波理论分析冲击载荷下的混凝土柱毁伤响应;结合数值模拟得出:同一比例距离不同爆距下钢筋混凝土柱的响应基本一致;同一爆距,随着药量增加崩落区域变大。

The caving phenomenon of concrete columns under impact loads was analyzed.The following conclusions were obtained:the use of one-dimensional stress theory can effectively analyze the damage response of concrete under impact load;The response of reinforced concrete columns under the same proportional distance and different blasting distances was basically the same.At the same detonation distance,the caving area becomes larger with the increase of charge amount.
