Abstract

In order to study the economy and reasonable structure of the orthotropic composite bridge panel, the loading modes of the most unfavorable position in the positive and negative bending moment zones under four kinds of live load were designed. The influence of U rib height, U rib center distance, and concrete layer thickness on the stress and economic performance of orthotropic composite bridge panel was analyzed by finite element method in four working conditions, and a reasonable structural dimension suggestion for a new type of steel-concrete composite bridge panel was obtained.
