摘要
针对大跨径波形钢腹板PC组合箱梁结构中的波形钢腹板的失稳破坏形式,分别对波形钢腹板的剪应力、局部屈曲强度、整体屈曲强度以及合成屈曲强度进行了计算,绘制出了波形钢腹板局部剪切屈曲界限图和整体剪切屈曲界限图,给出了波形钢腹板的一般设计方法和步骤,并将世界上已建的部分波形钢腹板PC组合箱梁桥的波形钢板的设计资料进行了归纳整理。验证结果表明,剪切屈曲界限图可用于波形钢腹板的参数设计,山东鄄城黄河大桥控制参数均位于适用范围内,为波形钢腹板的设计提供了依据。
Aimed at design of corrugated steel webs in structure of long-span PC composite box- girder with corrugated steel webs, shearing strength, local buckling strength and composite buckling strength were calculated. The graph about the local shear buckling limit boundary and the total shear buckling limit boundary are drawn based on the calculated results for the design of large span box-girder bridges with corrugated steel webs. Design materials of some box-girder bridges with the corrugated steel webs built in the world are summarized. The results indicate that geometrical parameters about corrugated steel webs can be designed with shear buckling limit boundary graphs. General design method and process which can provide reference for design of corrugated steel web summarized for the corrugated steel web. 1 tab, 3 figs, 10 refs.
