摘 要: | 薄壁箱梁受力复杂,为较好把握薄壁连续箱梁的受力行为,基于SAP2000对某三跨变截面连续薄壁箱梁进行有限元分析,分析结果表明支座移动对结构产生较大的内力,建议连续梁设计时在引起支座移动截面处设置铰来减小该处产生的内力。

Abstract: | Thin -walled box girder is complicated in bearing. In order to keep well the mechanics property of the girder, the paper performs analysis of thin - walled non - uniform continuous box girder based on SAP2000. The results of analysis indicate that the pedestal moving could bring structure to yield a large internal force, thus making suggestions that setting the hinge at the section causing the pedestal to move over design of the girder so as to reduce above -mentioned internal force. |
