摘要
计算分析钢筋混凝土中钢筋锈蚀量产生的膨胀应力是目前混凝土耐久性研究的重点问题。考虑混凝土中钢筋的不均匀锈蚀现象,应用有限元分析软件ABAQUS对钢筋锈蚀引起的混凝土内应力进行数值模拟,总结混凝土主拉应力的分布规律。
It is a key point in current research expansion stress generated due to corrosion of steel bars of concrete durability to calculate and analyze the in reinforced concrete. Considering the uneven rust on steel bars in reinforced concrete, finite element analysis software ABAQUS is used for numerical simulation of stress in concrete due to rusting of steel bar and distribution law of the main tensile stress of concrete is summarized.
