摘要
通过计算机有限元建立模型分析,探讨横向、纵向预应力对箱梁剪力滞效应的影响,得到相应的结论,并对箱梁桥设计中的相关问题提出建议。研究成果对箱梁桥设计具有一定的参考价值。
A model of the shear lag effect is made for a classical box girder so as to analyse the influence of prestressed function in landscape orientation and in vertical orientation on shear lag effect for box girder. Then some proposals are provided for the related problems in bridge design. In a sense, the results can be referred in designing box girder bridge.
