摘要:
基于OpenSees平台建立了桩-土-桥梁结构相互作用的非线性有限元模型,参照benchmark模型定义了8个斜拉桥性能评价指标,考虑脉冲型地震动的影响,分析了桩-土-结构相互作用对斜拉桥地震动响应的影响。研究显示,桩-土-结构相互作用效应对阻尼器减震效果的影响很大,无论是速度相关型阻尼器还是位移相关型阻尼器,大部分指标的控制效率均严重下降,特别是在脉冲型地震动作用下减震效率降低更加明显。
Abstract:
In this paper, the nonlinear finite element model of soil-pile-superstructure interaction was built based on OpenSees. Eight performance evaluation parameters of the cable-stayed bridge were defined according to benchmark model and the influence of pulse-type ground motion was considered. The influence of soil-pile-superstructure interaction on seismic response of cable-stayed bridge was analyzed by numerical simulation. The results indicate that the influence of soil-pile-structure interaction on seismic reduction effect of dampers is obvious for either velocity-relative type damper or displacement-relative type damper, the controlled effectivenesses of most index decrease seriously and particularly for the case of pulse-type earthquake action.
