| 摘 要： | 分析了自然气候中混凝土内钢筋锈蚀的机理,对混凝土内钢筋表面的锈蚀特征有了明确的认识,确定钢筋锈蚀主要在靠近混凝土保护层一侧产生;进而应用ANSYS有限元分析软件,对钢筋不均匀锈蚀膨胀引起的混凝土应力进行非线性有限元分析,总结了混凝土主拉应力的分布规律,并以此推断和解释混凝土的开裂趋势。

| Abstract: | Based on the theory of steel corrosion in concrete structure at atmospheric environment,this paper ascertains the characteristics of the corroded steel section,stating that the corrosion mainly arises at the side of concrete protection.By using the nonlinear finite element method and ANSYS software, we calculate the concrete stress based on non-uniform steel corrosion and summarize the distribution of the principal tensile stress.The results can be used to estimate the corrosive cracks in reinforced concrete members. |
