城市宽桥横向分布系数采用梁格法的计算探讨

城市桥梁一般比较宽,因此,其横向分布系数跟一般公路桥是有区别的。一些适用于公路桥梁的简化的横向分布系数计算方法对于城市宽桥未必适用。通过对梁格法、比拟正交异性板法(G-M法)、刚接梁法计算得到的宽桥横向分布系数的比较分析,了解了各种计算方法的误差,给实际工程设计提供参考。

Calculation Discussion on Urban Wide Bridge Transverse Distribution Coefficient by Beam Grid Method

The urban bridge is usually wider than the highway bridge, so its transverse distribution coefficient is different from the later. Some simplified calculation methods to the coefficient meet with the highway bridge, but they are probably not suit with the urban wide bridge. Through the comparative analysis of the wide bridge transverse distribution coefficient separately by beam grid method, G-M method and rigid-jointed beam method, the author provided references for the practical engineering designs.
