ANALYSIS AND RESEARCH ON SECTION PARAMETER OF FRP BRIDGE PANEL
摘要
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 rof 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. Under other circumstances the value is determined by the size of the roof and bottom. The material utilization is the highest when the thickness of the bottom is equal to the whole webs' and a little thinner than that of the roof.关键词
