【摘要】：基于Open Sees平臺建立了樁-土-橋梁結(jié)構相互作用的非線性有限元模型,參照benchmark模型定義了8個斜拉橋性能評價指標,考慮脈沖型地震動的影響,分析了樁-土-結(jié)構相互作用對斜拉橋地震動響應的影響。研究顯示,樁-土-結(jié)構相互作用效應對阻尼器減震效果的影響很大,無論是速度相關型阻尼器還是位移相關型阻尼器,大部分指標的控制效率均嚴重下降,特別是在脈沖型地震動作用下減震效率降低更加明顯。
[Abstract]:Based on the Open Sees platform, the nonlinear finite element model of pile soil bridge structure interaction is established. According to the benchmark model, the performance evaluation index of 8 cable-stayed bridges is defined. Considering the influence of pulse ground motion, the effect of pile soil structure interaction on the ground vibration response of the cable-stayed bridge is analyzed. The study shows that pile soil structure interaction is shown. The effect has a great influence on the damping effect of the damper. The control efficiency of most of the targets is greatly reduced, especially in the pulse type ground motion, and the reduction of the damping efficiency is more obvious.
