摘要
根据能量比拟原理 ,通过对箱梁桥面板作用车轮荷载后的应变能计算 ,得到其比拟简支正交异性板的刚度参数 ,再利用G -M法图表计算横向分布影响线 ,从而得到箱梁桥面板的荷载有效分布宽度 ,最后 ,对算例进行了计算 。
According to energy analogy method, this paper calculates the strain energy of the box girder deck under vehicle load, obtains the stiffness factors of the analogy simply-supported orthotropic plate. Then, the transverse distribution influence-line of the analogy plate can be calculeted using G-M method. And the load distribution width of the box girder deck is derived. Finally two calculating examples are given, and some characters of its are put forword.
