隔震层中设置碟形弹簧的竖向隔震研究
A STUDY ON VERTICAL SEISMIC ISOLATION OF ISOLATION LAYER WITH DISK SPRING
-
摘要: 基础隔震通常只考虑隔离水平地面运动,而对竖向地面运动的影响注意不够。在橡胶隔震支座上串联碟形弹簧,并给出了隔震层参数的确定方法和相应的力学模型。实例分析表明,新体系对竖向隔震效果显著。Abstract: The isolation of horizontal ground motion is usually considered in a base isolation. However, the influence of vertical ground motion is considered insufficiently . The disk springs are installed on the rubber bearing. The method of determining isolation layer parameter and mechanical models are also given. The vertical isolation effect of the new system is remarkable by analyzing examples.
