| Abstract: | The different section parameters of bridge panel is compared through the finite element analysis,and the deflection and first ply failure value are studied.The results show that,increasing of parameters of the bridge panel can reduce the deformation and increase the first ply failure value.The sizes of roof and webs have great influence on overall and local deformation,and that of the bottom and chamfer have little influence.The first ply failure value is determined by the webs when the webs are very thin.U... |
