摘要
钢筋锈蚀会影响钢筋混凝土偏压构件的抗弯刚度。论文基于ANSYS有限元程序,建立了同时考虑锈后钢筋力学性能下降、有效截面积减少以及钢筋与混凝土粘结性能退化的锈蚀混凝土偏压构件有限元计算模型,通过有限元计算结果和试验结果的对比,验证了论文所建有限元模型的可靠性。
Corrosion greatly influences the flexural stiffness of reinforced concrete eccentric compressive members.On the base of finite element software ANSYS,finite analysis model was founded considering the effects both to mechanical properties of steel bar and steel bar-concrete bond strength based on familiar part corroded members.Paralleling calculating result with the test proved the reliability of this model.
