RESEARCH ON APPLICATION OF FIBER REINFORCED POLYMER COMPOSITE STRUCTURE FOR DEFENSE WORK
-
摘要: 设计一种由玻璃钢管混凝土制作的新型抗冲击、抗爆炸的防护构件;分析了该新型防护构件的性能。研究表明,该构件既提高了混凝土的抗压强度,又提高了混凝土的延性,从而提高了其抗侵彻的能力。最后,利用LS-DYNA软件进行了数值仿真,结果表明,所设计的防护结构的抗侵彻能力比普通混凝土构筑的防护结构有很大提高。Abstract: The authors design an anti-penetration and anti-blast component that made of GFRP-pipe concrete and then analyze the merits of this component. The research shows that the concrete confined with GFRP-pipe can enhance compressive strength of concrete and increase its ductility. Therefore, the concrete confined with GFRP-pipe can improve the anti-penetration capability. In the end, the software LS-DYNA is used to simulate this process, and the results indicate that this defense structure design is much better than the normal one made of common concrete in terms of anti-penetration.
