摘　　要：通过两组HHT600高强混凝土(RC)板和普通RC板的抗爆炸试验,研究裂缝的产生、开展过程,分析了这两种板的压力、位移、加速度、应变时程响应及破坏特征。结果表明:板配筋采用HHT600级高强钢筋,能有效减少裂缝的开展,提高钢筋混凝土板的抗爆性能。研究成果为高强钢筋在防护结构中的推广使用及设计提供参考。The explosion resistance performance of two groups high-strength RC slabs and the common RC slabs were experimentally studied to explore the failure mechanism,development and distribution of cracks.The dynamic time history responses to structural loads,deflections,acceleration and strains of steel bars,and the failure modes of the slabs were also investigated.The results indicate that adoption of HHT600 high-strength steel bars can reduce development of cracks effectively and enhance the explosion resistance performance of RC slabs.The researched result can provide a reference for introducing the high-strength bars into the protective structure and explosion resistance design of the protective structure.
