弯箱梁桥面板受力特性分析

With the construction and implementation of bridge engineering, although the straight bridge has a Specifications requirements on our country, but in particular, no consist of the Standard requirements of bent bridge, on the paper the straight bridge deck and bent bridge deck are analysed by the finite element program ANSYS10. 0. From the deflection we find the differences between bent box beam deck and box beam deck . It can be seen from the analysis, when the radius of large, bent bridge deck can be as reinforced of steel as straight bridge deck, but with small radius ,it need of the reinforcement for inner and outer bent bridge deck according to difference
