摘要:
为研究聚丙烯纤维混凝土在接触爆炸条件下的破坏形态,进行有限厚度钢筋混凝土板和聚丙烯纤维混凝土板的接触爆炸试验。采用LS-DYNA中LOAD-BLAST方法,对聚丙烯纤维混凝土的动态破坏过程进行数值模拟,分析和对比聚丙烯纤维混凝土和钢筋混凝土接触爆炸条件下破坏效应的异同,确定出聚丙烯纤维混凝土的抗爆性能系数。研究表明,LOAD-BLAST方法简单高效,数值模拟和现场试验非常吻合,聚丙烯纤维混凝土抗接触爆炸性能良好。
Abstract:
In order to study the damage to polypropylene fiber reinforced concrete slab subjected to contact blast loading,experiments of the limited thickness reinforced concrete slab and polypropylene fiber reinforced concrete slab were carried out.The deformation and the dynamic damage processes of the polypropylene fiber reinforced slabs were simulated using LOAD-BLAST methods in LS-DYNA programs and differences of damage were investigated between reinforced concrete slab and polypropylene fiber reinforced concrete slab. The value of anti-detonation coefficient was ascertained. The results show that LOAD-BLAST method is advantageous and effective, and the numerical results agree well with the experimental data.
