钢筋混凝土板的爆炸荷载试验研究

在爆炸波的影响下,钢筋混凝土(RC)板(如:楼面和剪力墙等)既是建筑结构中受爆炸荷载作用的主要受力构件,又是建筑结构破坏的薄弱环节,而且,其破坏还直接导致建筑结构的整体刚度退化和动力响应升级.选择建筑结构中楼面设计常用的钢筋混凝土简支单向板为试验对象,对两个完全相同的试件分别进行独立的爆炸试验--爆炸I和爆炸II,分别观测钢筋混凝土板在弹性区域的动力响应(爆炸I)和塑性区域的破坏特征(爆炸II).实验为后续进行的受爆炸荷载的钢筋混凝土板碳纤维(CFRP)加固试验研究提供了有效的基础数据和可靠的参照,实验观测到的现象和数据也可供同类研究参考.

Experimental studies on reinforced concrete(RC) slabs subjected to blast loads

Influenced by the blast waves,the reinforced concrete(RC) slabs,such as floors and shear walls,not only are the main structural components of a building under the blast loads,but also are the weakest links in the building failure,and their failure directly induces the structural stiffness degradation and the structural blast-response upgrading.In this paper,the RC simply supported one-way slabs,which are used commonly in the buildings,were selected as experimental objects.Blast test was performed on two rei...
