摘要:
以跨度为120m的刚性拱肋柔性系杆的下承式钢管混凝土拱桥为分析模型，利用摩擦摆减震隔震支座对简支体系的桥跨结构进行减震研究，运用MIDAS有限元软件模拟多维人工地震波输入以检验摩擦摆系统的减震效果。分析结果证明了在大跨度钢管混凝土拱桥中应用摩擦摆隔震支座系统的有效性。
Abstract:
The effect of friction pendulum vibration isolation and damping bearings on the vibration damping of simply supported arch structure of a rigid concrete-filled steel tubular arch bridge was analysed. The arch bridge has a span of 120 m with flexible column lower bearing. Finite element model MIDAS was employed to simulate the multidimensional artificial seismic wave input to investigate the damping effect of the friction pendulum bearing system. The results indicate that the friction pendulum bearing system is effective in the vibration damping of the large span concrete filled steel tubular arch bridge.
