远场地震动作用下地铁车站结构动力响应分析
|
摘要
基于ABAQUS有限元软件,针对深软场地条件,建立了土-结构动力相互作用模型。利用Python二次开发程序实现了黏弹性边界的自动施加。考虑远场大震波及人工波的不同频谱特性,对典型两层三跨地铁车站结构动力响应进行了研究。结果表明:车站结构动力响应受输入地震动的峰值加速度及频谱特性影响明显,结构在不同地震波作用下关键部位的内力及位移变化趋势一致。大震远场波作用下和人工波作用下的车站相对位移曲线形状有差异。对于典型的框架式地下车站而言,中柱的内力反应最大,为最不利受力构件,设计时应重点考虑。深软场地对地震波具有低频放大、高频滤波的效果,远场大震波中的低频含量丰富;与人工波作用相比,车站关键位置地震动峰值加速度(PGA)增大明显。
Based on the ABAQUS finite element analysis software,for deep soft site conditions,soil-structure dynamic interaction model is established. The automatic application of viscoelastic boundary is realized by using Python secondary development program. Considering the different spectral characteristics of the far field and the artificial wave,the dynamic response of the two-story three-span subway station structure is studied. The results show:the dynamic response of the station structure is affected by the peak acceleration and spectral characteristics of the input ground motion and the internal force and displacement trend of the key parts under different seismic waves are consistent. The relative displacement curve of the station under the action of large field wave and artificial wave is different. For a typical frame underground station,the internal force of the column is the largest,which is the most disadvantaged component. Design should focus on consideration. The soft ground has the effect of low frequency amplification and high frequency filtering for seismic waves. The low frequency is rich in far field large seismic waves. Compared with the effect of artificial wave,the peak acceleration of the station( PGA) increases obviously.
