波形钢腹板箱梁腹板受力分析

Force Analysis of Web Plate of Corrugated Steel Web Box Girder

波形钢腹板具有重量轻、抗剪能力好等优点,近年来应用广泛。当波形钢腹板与混凝土腹板混合组成断面时,二者受力会有明显的不同。通过分析波形钢腹板与混凝土腹板混合截面下的超宽主梁在不同内力作用下各腹板的受力特征,以腹板剪力分配为出发点,分析恒载及活载下的腹板剪力分配状况,以期为该类桥梁的设计提供参考。

The corrugated web has been used widely for its light weight and good shear resistant.When the corrugated steel web is mixed with the concrete web to form a section,the force of the two webs will be obviously different.In this paper,under different internal forces,the force characteristics of each web of the mixed section of the corrugated steel web and the concrete web were analyzed.Starting with the web shear distribution,the web shear distribution under dead load and live load was analyzed,in order to provide reference value for the design of this kind of bridge.
