Studying on the Anti-explosion Performance of SRP Reinforced Concrete Materials

针对钢筋混凝土等基础结构容易遭到破坏的问题,选择高强度SRP材料加固钢筋混凝土作为研究对象,借助有限元分析软件AOTUDYN开展研究工作.通过显示动力分析软件AOTUDYN对选取的试件建立模型.利用SRP材料分三种加固方式对钢筋混凝土进行加固,并通过计算分析爆炸情况下各个测点的速度时程曲线及位移时程曲线,对比未加固RC和加固RC的爆炸响应.利用位移峰值、残余位移值等指标,全面研究SRP材料加固层数与抗爆性能间的关系.结果表明,SRP材料能够进一步改善钢筋混凝土抗爆性能.

Aiming at the problem that the concrete structure is easy to be destroyed, the high strength SRP material as the research object is used to strengthen the reinforced concrete, and using the finite element anal- ysis software AOTUDYN to carry out the research work in this paper. First of all, the dynamic analysis soft- ware AOTUDYN is used to establish the model. Then, the SRP materials are divided into three kinds to rein- force concrete, and the velocity curve and displacement curve of each measuring point are analyzed. In addi- tion, comparisons are made for the explosion responses of no reinforcement RC and reinforcement of RC. Fi- nally, the relationship of SRP reinforcement layers and the anti explosion performance through the displace- ment peak value and residual displacement value are studied. The results show that SRP materials can further improve the antiknock performance of reinforced concrete.
