摩擦摆系统(FPS)是现在世界上广泛用于桥梁加固改造的隔震支座,为评价其在桥梁隔震中的表现,需要建立计算模型来反映这些高度非线性构件之间的相互作用。主要介绍一种新的FPS模型及其建模机理,此模型可以在非线性动力响应分析中更好地反映法向力与摩擦系数的变化,考虑双向耦合以及大变形效应的影响,并给出一个三维多跨连续钢箱梁桥的地震动响应分析实例及分析结果。
Friction pendulum system (FPS) is widely used in the world nowadays. It is necessary to establish a computational model to reflect the interaction between these highly nonlinear members. This paper mainly introduces a new FPS model and its modeling mechanism. This model can better reflect the change of normal force and friction coefficient in the nonlinear dynamic response analysis, and consider the influence of bidirectional coupling and large deformation effect A Case Study of Three-Dimensional Multi-Span Continuous Steel Box Girder Bridges and Analysis Result.
