钢纤维聚合物混凝土修补梁抗爆性能试验研究

Test study on the explosion-resistant performance of steel fiber reinforced polymer concrete repaired beams

为了研究钢纤维聚合物混凝土在爆炸荷载作用下的抗爆性能，对C30普通混凝土梁、聚合物混凝土和钢纤维聚合物混凝土修补梁在非接触爆炸条件下的动态响应进行了研究，描述了其宏观破坏现象，对比分析了聚合物混凝土和钢纤维聚合物混凝土以不同修补方式形成的修补梁的变形特征及破坏特征。研究结果表明：钢纤维聚合物混凝土修补梁性能明显优于普通混凝土和聚合物混凝土修补梁。

In order to research the explosion-resistant on normal concrete beams, polymer concrete repaired performance of steel fiber reinforced polymer concrete, tests beams and steel fiber reinforced polymer concrete repaired beams were carried out under non-contact explosion loading, respectively. The macro damage phenomena are described, and the deformation characteristics and damage characteristics at the bottom of the repaired beams with dif- ferent repair manners are analyzed. It is demonstrated that the performance of steel fiber reinforced polymer concrete repaired beam is much better than that of the other beams.
