| Abstract: | In the light of the characteristics of the road structures and highway load standards in China,this paper analyzes and makes a study of the governing factors of the design and reasonable section sizes of main girders of the simply-supported highway steel and concrete composite girder bridges,gives the deflection of the girders in case the design is governed by stress under Class I Highway Traffic Load and the approximate formulas for relations between the flange areas and span length of the girders,and also compares the composite girder bridges with the non-composite ones. |
