摘要
提出了一种分离式三维隔震结构设计方法,将竖向隔震层和水平隔震层分开布置,实现它们的解耦,进行设计计算时更加方便快捷.根据这种方法制作了一个2层钢框架模型,与非隔震结构模型一同进行振动台试验,对试验结果进行对比分析,试验结果表明分离式三维隔震结构模型加速度反应和层剪力均小于传统结构模型,三维隔震效果良好.
This paper proposes a design method for the separation type 3D isolated structure,where the vertical isolation layer and the horizontal isolation layer are in separate arrangement in order that both layers are decoupling and the design calculation is more convenient and quicker. According to this method,a 2-floor steel frame model is built as a 3D isolated structure. The simulated earthquake tests on the designed isolated model and a non-isolated structure model are then carried out by a shaking table. The experimental results shows that peak acceleration and floor shear of the separation type 3D isolated structure model are less than that of the non-isolated structure model. It is illustrated that the effect of the 3D isolation is good.
