水平竖向复合隔震墩减震性能试验研究

Research on Isolation Properties of Isolation Pier in Transverse and Vertical Direction

根据住宅的结构特点和基础隔震理论,设计了种新型三维隔震装置——水平竖向复合隔震墩,该隔震墩可以同时减弱水平地震作用和竖向地震作用对上部结构的影响。介绍了复合隔震墩的构造、工作原理,并以混凝土质量块代替刚度较大的上部结构,对复合隔震墩隔震体系模型进行了振动台模拟地震试验,试验结果表明复合隔震墩具有良好的三维隔震性能。

Based on the rural residence structure characteristics and base isolation theory,a new 3D isolation pier is designed to resist the seismic action in both horizontal and vertical direction. The composite isolation pier can reduce the impact of horizontal and vertical direction seismic action to upper structure. Authors introduce the composite isolation pier structure and working principle,and doing the shaking table test in both horizontal and vertical direction thinking concrete slab as the research object, and the results show that the composite isolation pier vibration isolation system has good 3D isolating affection.
