| Abstract: | Taking Guanyinyan Yangtze River Bridge at Jiangjin of Chongqing as the example,the paper analyzes the stability issue of the steel-concrete composite beam and main beam,calculates the elastic stability coefficient of the under-beam section of the design for the loading combination and the elastic and stable critical force under the effect of the self-defined loading,so as to provide the theory reference for the design of the bridge. |
