| 摘 要： | 运用有限元方法,对27座不同几何截面形式的简支梁桥模型进行了仿真分析,在考虑了跨度、分离式箱体的个数、行车道数目的基础上,根据城市桥梁荷载得出了最大应力、挠度和剪力分配系数的经验公式,可供设计参考.并为我国城市桥梁规范的修订提供参考.

| Abstract: | By means of finite element method, this paper studies 27 simple-supported bridges with different cross-section, and concludes the experienced formulas for the maximum load distribution of stress,deflection and shear considers the parameters such as span, the number of separated boxes and lanes,which can provide preference for bridge design and the emending of municipal bridge design code. |
