钢筋严重锈蚀偏心受压柱承载力有限元分析

Finite Element Analysis of Bearing Capacity of Corroded Eccentric Compression Concrete Column

钢筋锈蚀会造成钢筋有效面积减小和钢筋与混凝土粘结性能下降,致使钢筋混凝土柱承载力降低,影响结构安全。文章通过有限元软件ABAQUS建立数值模型,研究钢筋锈蚀长度对钢筋严重锈蚀偏心受压混凝土柱承载力的影响。研究结果表明锈蚀长度越长,钢筋严重锈蚀偏心受压柱承载力越低。

Corrosion of steel bars will reduce the effective area of steel bars and the bonding performance between steel bars and concrete,which will reduce the bearing capacity of reinforced concrete columns and affect the structural safety.In this paper,finite element software ABAQUS is used to establish a numerical model to study the influence of the length of steel corrosion on the bearing capacity of steel corrosion eccentric compression concrete columns.The results show that the longer the corrosion length,the lower the bearing capacity of the corroded eccentric compression concrete column.
