脉冲荷载作用下土中浅埋钢筋混凝土框架直剪破坏分析(Ⅱ.应用)

ANALYSIS ON DIRECT-SHEAR FAILURE OF SHALLOW-BURIED RC FRAMES SUBJECTED TO IMPULSIVE LOADING(Ⅱ APPLICATION)

本文应用文献 [5 ]所提出的计算方法 ,分析了集团装药爆炸条件下土中浅埋框架迎爆面构件的动力响应及破坏模式 ,并分析了影响结构直剪破坏的因素。最后通过大量计算 ,给出了集团装药爆炸条件下土中浅埋钢筋混凝土框架发生直剪破坏的条件。

The dynamic response and failure mode of the structural component close to the blast point of the shallow_buried RC frames subjected to conventional weapons explosion are investigated by the proposed analytical approach [5] .The factors affecting the occurrence of the direct_shear failure mode are given,and the relationships between M u,Q uand R/W 1/3  when the direct_shear failure occurs are also plotted.
