摘要:
依据变截面波形钢腹板组合箱梁特点,考虑梁高、底板厚度的变化,从弹性微元段的受力平衡出发,推导钢腹板剪应力计算公式,结果表明,箱梁剪力由混凝土顶、底板和波形钢腹板共同承担,变截面波形钢腹板梁中的剪应力除了由截面剪力引起外,还包括有截面弯矩和轴力引起的附加剪应力;通过与等截面计算公式和有限元数值计算结果对比验证,表明笔者给出的计算公式具有较高计算精度;最后在此基础上考虑3种荷载工况,给出一变截面波形钢腹板箱梁的剪力传递效率.
Abstract:
Based on characteristics of the variable cross-section box girder with corrugated steel webs,considering girderheight and bottom plate from the force equilibrium of thickness,the elastic element,the web’ s shear stress formula was derived.It was shown got that shear stress of variable cross-section composite box girder with corrugated steel webs was sheared by top and bottom concrete plate and corrugated steel webs.It was concluded that the variable cross-section composite box girder’ s shear was caused by the section’s shear force,in addition,also including additional shear stress which was produced by bending moment and axial force.Through comparing of the formula solutions section and variable’ s formula and FEA results of constant section,it is indicated that the shear stress calculation formula has higher calculation precision.Finally,based on testing the formula,taking into account three load cases,variable cross-section box girder with corrugated steel webs shear force transfer efficiency was given.
