摘要
为了研究地震作用下简支梁桥的碰撞响应,本文通过建立全桥模型,在输入不同的地震激励、考虑不同桥墩高度下,进行了简支梁桥地震响应时程分析。结果表明:地震作用下碰撞在一定程度上显著地改变了桥梁结构的响应状态,增大了墩底的弯矩和剪力;桥墩的高度和地震激励的变化会对梁间碰撞产生影响。
In this paper, the characteristic of simple - supported bridges are ear analysis, during differ seismic waves and differ height of pier. The result in a certain extent, changes evidently the structural response and increases forces on pier bottom. The pier height and seismic input effect the pounding investigated is found that by nonlin- pounding, the moment and shear of adjacent segments.
