锈蚀钢筋压屈承载力试验研究及有限元分析
|
摘要
在实验室采用直流电源进行电化学加速锈蚀钢筋,从而获得不同直径、长径比和锈蚀率的锈蚀钢筋试件,然后在万能电子试验机上进行压屈试验,获得锈蚀钢筋压屈承载力曲线。经过统计分析,得到四种形态的锈蚀钢筋压屈承载力计算模型。应用大型有限元分析软件AN SY S对锈蚀钢筋压屈承载力模型进行进一步验证。
Corroded reinforcements,with various diameters,length-to-diameter ratios and corrosion rates,are obtained from the lab by using DC electrical sources to accelerate corrosion.The buckling capacity curves of corroded reinforcements are gained from electronic universal testing machine in the buckling test.The buckling capacity computational model of corroded reinforcement can be generalized in four types that are verified by the application of finite element analysis software ANASYS.
