本研究探讨了钢板梁桥承载区附近局部腐蚀损伤（包括加劲肋和相邻腹板损伤）对钢板梁桥抗剪极限承载力和屈曲后承载力的影响。一个计算机软件包ABAQUS是用于验证和扩展的数值研究。考虑不同的损伤厚度和损伤高度，研究了各种腐蚀损伤情况，特别是加劲肋。研究结果表明，对于板梁的抗剪性能而言，加劲肋的局部损伤比腹板的局部损伤更为致命。此外，还推导了局部锈蚀板梁承载区剩余抗剪承载力的经验关系式。
This study discusses the effect of local corrosion damages nearby the bearing region including the bearing stiffener and adjacent web damage on the ultimate shear and post-buckling strength of steel plate girder bridges. A computer package ABAQUS is utilized for the verification and extension of the numerical study. Various corrosion damage cases, specifically the bearing stiffener are studied considering different damage thickness and damage heights. The study concludes that local damage on bearing stiffener damage is more fatal than the local web damage for the shear resistance of the plate girder. Further, some empirical relationships are also derived to assess the residual shear capacity of the locally corroded plate girder at the bearing region.
