减振双曲形钢支座在空间结构中的应用

支座是一种薄弱构件 ,其抗震能力必须加强。万向承载、万向转动、减振双曲形钢支座的抗震能力很高 ,可承受压力、拔力、任意方向的剪力。并以一个实际工程为例 ,用大型结构分析软件对工程结构进行地震响应分析 ,比较了采用减振支座前后的地震响应结果 ,在保证相对位移满足要求下 ,减振效果可达 2 0多倍 ,减振效果极为明显。

APPLICATION OF HYPERBOLIC DAMPING IRON BEARING IN SPACE STRUCTURE

Bridge bearing is a weak constructional element,so its earthquake resistant ability should be strengthened.The earthquake resistant ability of a universal load-supporting and rotating hyperbolic bridle iron stated in this paper is very effective,and it can bear pressure,pulling force and shear force in any direction.A real engineering case is involved to analyse the structure′s seismic response by a large-scaled structure analysis software.The calculation results before and after using this damping bearing are compared.Provided that the relative displacement is less than the limits,the damping effect can be up to more than 20 times.So the damping effect is very obvious.
