| 摘 要： | 通过粘钢实现一典型汽车库人防口部封堵的设计方案,采用有限元分析软件对其进行三维有限元数值分析,采用八节点六面体单元离散顶板、底板、封堵板、粘接钢板、H型钢、混凝土顶板、底板及封堵板与钢板之间拟设置接触面单元模拟粘胶的性态,得到H型钢与钢板、H型钢与混凝土、角钢与混凝土之间的粘结应力,并和粘接胶强度进行对比后得出结论:在对汽车库人防口部封堵设计中,采用粘钢技术可以满足人防口部的封堵设计要求,由此论证了这类技术用于平战功能转换的可能性和优越性。

| Abstract: | In this paper,by bonding steel plates the desiqn project of a gateway of a typical garage is carried out,and three dimensional FEM is adapted to a gateway of defense structure of a typical garage streugthened by steel plates.A 3D friction contact element method is developed in this paper.The results show that the technology of strengthening by bonding steel plates can fulfill the design ability of a gateway of defense structure to close up a typical garage.And the method proves to be of possibility used for functional transformation from peacetime to wartime. |
