摘要
通过锈蚀钢筋混凝土梁抗弯承载力试验,在已经提出的基于锈胀裂缝宽度的锈蚀率计算方法基础上,根据承载力试验结果建立了基于计算锈蚀率的锈蚀梁承载力计算方法,同时提出了锈蚀梁危险截面位置的预测方法,与已有研究成果的对比表明,该方法具有良好的准确性和实用性,可以为锈蚀梁残余承载力和危险截面的预测提供参考。
The forms and characteristics of the corroded beams are analyzed through flexural capacity test for corroded beams. According to test results and corrosion rate calculation method obtainded by the authors, calculation method of flexural capacity for corroded beams, as well as Campared to existing research results, adequate accuracy and residual flexural capacity and dangerous section prediction of dangerous section prediction method is established. practicability of this method can provide reference for corroded beams.
