Anti-shearing design method for corrugated steel web composite girder bridge and corrugated steel web composite girder bridge
The invention discloses a corrugated steel web composite beam bridge shear resistance design method and a corrugated steel web composite beam bridge. The corrugated steel web composite beam bridge shear resistance design method comprises the following steps that design parameters of a composite beam bridge are drawn up; calculating a total shearing force design value V borne by the cross section of the composite beam bridge according to the Timoshensingson beam theory; calculating the design value Vf of the shearing force borne by the wing plate, and calculating the anti-shearing bearing capacity VRf of the wing plate; calculating the design value Vw of the shearing force borne by the corrugated steel web, and calculating the shear bearing capacity VRW of the corrugated steel web; calculating ratios lambda f = Vf/V and lambda W = VW/V; checking whether the relational expressions Vf < = VRf and VW < = VRW are met or not, if all the relational expressions are met, the anti-shear design requirement is met, if any relational expression is not met, returning to modify the design parameters of the composite beam bridge, and checking again. According to the anti-shearing design method for the corrugated steel web composite beam bridge, the shearing force borne by the wing plate can be considered and checked, the anti-shearing efficiency of the composite beam bridge is fully exerted, and the wing plate is prevented from being subjected to shearing damage.
本发明公开了一种波形钢腹板组合梁桥抗剪设计方法及波形钢腹板组合梁桥，包括以下步骤：拟定组合梁桥的设计参数；根据铁木辛柯梁理论计算组合梁桥的横截面承受的总剪力设计值V；计算翼板承受的剪力设计值Vf，计算翼板的抗剪承载力VRf；计算波形钢腹板承受的剪力设计值Vw，计算波形钢腹板的抗剪承载力VRW；计算比值λf＝Vf/V和λW＝VW/V；验算是否满足关系式Vf≤VRf、VW≤VRW和全部满足则符合抗剪设计要求，任一关系式不满足则返回修改组合梁桥的设计参数，重新验算。本发明的波形钢腹板组合梁桥抗剪设计方法能够考虑并验算翼板承受的剪力，充分发挥了组合梁桥的抗剪效率，防止翼板发生剪切破坏。
