本文介绍了数值建模技术，以捕捉行为的三重摩擦摆（TFP）隔震支座时，允许旋转的顶部和底部组件的水平轴。本文建立在作者提出的TFP轴承的运动学和本构关系的基础上的TFP轴承的各个部件以前的模型。通过数值计算，研究了支座转动对支座循环承载性能和抗震性能的影响。结果发现，恒定的支持旋转应限制在振幅，以确保标准的TFP轴承的行为。结果表明，只要满足支撑构件的典型变形极限，柔性支撑可能不会对整体结构性能产生很大影响。在恒定的支撑旋转和柔性支撑的情况下，TFP轴承行为的硬化阶段减少。版权所有© 2013约翰威利父子有限公司.
This paper presents numerical modeling techniques to capture the behavior of the triple friction pendulum (TFP) isolation bearing when rotation is permitted about the horizontal axes of the top and bottom components. This paper builds on a previous model for the TFP bearing presented by the authors that is based on the kinematic and constitutive relationships of the individual components of the TFP bearing. The effect of rotation on cyclic bearing behavior and seismic system behavior are investigated numerically for two cases: constant support rotation and variable support rotation. It is found that constant support rotations should be limited in amplitude to ensure standard TFP bearing behavior. Results suggest that flexible supports may not have a large effect on global structure performance as long as typical deformation limits for the supporting members are met. In cases of both constant support rotations and flexible supports, the hardening stages of TFP bearing behavior are diminished. Copyright © 2013 John Wiley & Sons, Ltd.
