摘要:
为揭示跨走滑断层多跨简支梁桥的地震响应规律,以1座4跨简支梁桥为研究对象,基于OpenSees建立了3维动力弹塑性分析模型; 采用“分解-叠加”法合成40组跨断层地震动,以多点激励的方式输入到建立的动力分析模型,进行非线性动力时程分析,研究了跨走滑断层多跨简支梁桥在地震动作用下的地震反应特征,分析了断层的穿越角度和穿越位置对跨走滑断层多跨简支梁桥地震响应的影响。结果表明:地震动作用下跨走滑断层桥梁结构会发生剧烈的位移反应; 断层穿越角度和穿越位置对桥梁地震反应有显著的影响; 地震动作用下跨断层简支梁桥的扭转效应不可忽视。
Abstract:
To investigate the seismic response of the multi-span simply supported girder bridge across the strike-slip fault,a 3-dimensional dynamic elastic-plastic analysis model is established for a 4-span simply supported girder bridge by using OpenSees.Forty sets of bidirectional ground motions across the fault are synthesized by the decomposition-incorporation method.These ground motions are then input into the model through multi-support excitation.A dynamic nonlinear time history analysis is carried out to investigate the seismic response of the multi-span simply supported girder bridge under the action of the ground motions across the strike-slip fault.In addition,the effects of the crossing angle and the crossing position of the multi-span simply supported girder bridge across a strike-slip fault on the bridge are analyzed.The results show that the bridge under the action of the ground motions across a strike-slip fault will experience a significant displacement response.Both the crossing angle and the crossing position have a significant effect on the seismic response of the bridge.Additionally,the torsion effect of the simply supported girder bridge under the action of the cross-fault ground motions should not be neglected.
