摘要 弹簧摩擦摆式支座是在传统摩擦摆式支座的基础上开发的新型减隔震产品,根据力学平衡原理对摩擦摆式支座和弹簧摩擦摆式支座进行了理论分析,利用结构分析软件sap2000对两种支座在桥梁中的动力特性和地震响应进行了对比分析。结果表明,弹簧摩擦摆式支座自回复性能优于摩擦摆式支座,但其减隔震性能弱于摩擦摆式支座。 Spring friction pendulum bearing is a new isolation product which is developed on the basis of the traditional fric- tion pendulum bearing. According to the principle of mechanical balance, friction pendulum bearing and spring friction pendulum bearing are theoretically analyzed. By using structural analysis software sap2000, the dynamic characteristics and seismic responses of two kinds of bearings in bridge are contrastively analyzed. The comparative analysis shows that the self- reset performance of spring friction pendulum bearing is better than that of friction pendulum bearing, but its seismic isola- tion performance is weaker than that of friction pendulum bearing.
