摘　　要：依据试验结果,运用有限元软件对均布荷载作用下箍筋锈蚀钢筋混凝土梁作了弹塑性数值模拟计算。根据分析结果,对其抗剪机理及破坏时裂缝形式了探讨,揭示了随箍筋锈蚀率的变化,钢筋混凝土梁的抗剪极限承载力劣化,破坏裂缝形式发生变化。为今后进行数值试验和影响因素分析作了初步研究。Based on the experimental results,FEM method is used to analyse corroded reinforced concrete beams with stirrups subject to uniformly distributed load.The shear carrying mechanism and forming of failure cracks are explored.It can be concluded that shear ultimate carrying capacity is deteriorated and failure cracks is changed due to the corrosion of stirrups.

关 键 词：混凝土结构耐久性 箍筋锈蚀 有限单元法 抗剪承载能力
