钢筋混凝土对边简支板的爆炸试验

爆炸载荷作用下钢筋混凝土板是建筑结构破坏的薄弱环节，其破坏还导致结构整体刚度 退化和动力响应升级. 以对边简支钢筋混凝土板为试验对象，在两个相同的试样上进行独立 的爆炸试验，观测钢筋混凝土板在弹性区动力响应和塑性区破坏特征，为碳纤维加固钢筋混 凝土板抗爆炸试验研究提供有效的数据和参照，实验现象和数据可供同类研究参考.

BLAST EXPERIMENTS OF THE REINFORCED CONCRETE SLABS SIMPLY-SUPPORTED AT BOTH ENDS

Under blast loads, reinforced concrete slabs are usually weak links in building structural failure, which in turn induces the structural stiffness degradation and results in the structural blast-response upgrading. The reinforced concrete slabs simply supported at both ends were selected as experimental objects, the blast experiments were performed on two same specimens to investigate the dynamic response of the reinforced concrete slab in the elastic range and the failure characteristics in the plastic range. The experimental results provide some effective data and comparisons in the development of experimental study on the reinforced concrete slabs retrofitted with carbon fiber reinforced polymer sheets under blast loadings, and also serve as references for similar researches.
