一种新型钢棒隔震器的研究
|
摘要
传统的抗震方法通过增强结构本身的承载力、刚度和延性来抵抗地震作用,虽然地震时建筑物没有倒塌,但因结构和一些投资很高的设备及豪华装修等遭到破坏,所造成的损失却十分巨大.因此,隔震建筑的研究和发展越来越成为世界关注的重点.针对现有隔震技术存在的问题,本文提出一种新型的钢棒隔震器,其具有竖向承载力高,水平刚度小,构造简单和材料普遍等突出优点.采用ANSYS有限元软件模拟钢棒隔震层的方法,建立三维砌体基础隔震结构模型,从理论上探讨了这种钢棒隔震器的可行性.
The traditional method of anti-seismic to resist earthquake through enhancing the carrying capacity of the structure,stiffness and ductility.Though the building doesn't collapse when the earthquake happen,but because of the structure,equipment with high investment and luxurious decoration destruction caused enormous losses.Therefore,the research and development of the isolated building has become the focus of world attention increasingly.For the existing isolation technology issues,this paper proposes a new type of steel bar isolator.It has some outstanding advantages,such as vertical bearing capacity,small horizontal stiffness,simple structure and universal material.In this paper,using the finite element software ANSYS to simulate steel bars isolation layer,building three dimensional masonry base isolation structure model,investigating the feasibility of such a steel bar isolator theoretically.
