Abstract: In this paper,the general formulation for calculating the transverse load distribution influence lines of the girder bridges is presented, based on the G-M method. The method for computing the transverse load distribution influence lines of the girder bridges with inequal web-distance is proposed and illustrated with an actual engineering example.

Key words: transverse load distribution, G-M method, girder bridges with inequal web-distance

摘要： 本文应用G-M比拟正交异性板法(简称G-M法)现有图表计算简支肋梁桥主梁荷载横向分布影响线,提出了主梁布置不均匀的简支肋梁桥荷载横向分布影响线的计算方法,并通过一工程实例说明具体计算步骤。
