摘要:
减隔震型支座作为桥梁实现抗震、减震的有效方法和重要手段，已经成为桥梁抗震设计的首选。双曲面球型减隔震支座具有双球面的球体，利用简单的钟摆机理延长桥梁的自振周期，从而降低加速度反应，并通过桥身自重提供所需的自复位能力，帮助桥梁上部结构回到原来的位置，具有完备的减震功能，良好的耐久性能，适合在震区桥梁上大面积推广使用。
Abstract:
Isolation bearing has become a preferred choice of aseismic design of bridge regarding as effective and important solution for resisting earthquake. Hyperboloid spherical solution bearing has hyperboloid sphere, using simple pendulum mechanism to extend bridge natural vibration period to reduce acceleration reactions. And the bearings help superstructure of bridge restore original position through self-restoration due to bridge self-weight. In conclusion, spherical isolation bearings possess complete earthquake resisting function and good durability which are suitable to be widely applied on bridges in seismic zone.
