钢筋混凝土框架结构在爆炸荷载下的动力响应及破坏分析

采用有限元软件SAP2000模拟钢筋混凝土框架在不同峰值的爆炸荷载下的动力响应过程。通过对结构各构件在不同峰值爆炸荷载下的位移对比分析,结果表明在钢筋混凝土框架中受爆炸荷载直接作用的那部分构件位移变形非常大的,是远离爆炸荷载那部分构件位移的几十倍,说明爆炸荷载作用下结构构件的破坏具有一定的局部性。分析结果还表明当爆炸荷载较大时结构构件有可能发生剪切破坏而导致整个结构在短时间内整体破坏。

Dynamic response and failure analysis for the RC frame structure under explosion Load

In this paper,finite element analysis software SAP2000 was used to simulate the dynamic response of RC frame under the explosion loads with different peak levers.According to the displacements of the various components under the different explosion loads,the results show that the displacements of the elements affected by the explosion loads directly are several times larger than that of elements far away from the explosion loads.It Notes that the destruction of structural components under explosive loads ha...
