钢筋锈蚀轴心受压混凝土柱承载力有限元分析

Finite element analysis of bearing capacity of corroded axial compression concrete column

通过有限元软件ABAQUS建立数值模型研究钢筋锈蚀长度、粘结程度和锈蚀根数对钢筋锈蚀轴心受压混凝土柱承载力的影响。研究结果表明:粘结程度越低,锈蚀根数越多,钢筋锈蚀轴心受压混凝土柱承载力越低。

In this paper,finite element software ABAQUS is used to establish a numerical model to study the influence of the length of steel corrosion,the degree of bond and the number of corrosion roots on the bearing capacity of steel corrosion axial compression concrete columns. The results show that the lower the degree of bond,and the more the number of corrosion roots,the lower the bearing capacity of the corroded axial compression concrete column.
