基于27个型钢再生混凝土柱轴心受压和偏心受压试件的试验实测数据,利用传统型钢混凝土结构计算理论和我国相关设计规程,探讨了型钢再生混凝土柱的极限承载力计算方法。研究结果表明:JGJ138—2001《型钢混凝土组合结构技术规程》计算型钢再生混凝土偏压柱,计算值与试验值吻合较好,但传统型钢混凝土理论计算型钢再生混凝土轴心受压柱,以及YB9082—2006《钢骨混凝土组合结构规程》计算型钢再生混凝土偏压柱,计算值大于试验值,不安全。最后提出了实用计算公式,研究结果可供型钢再生混凝土组合结构的工程应用提供参考。
Based on 27 axial and eccentric compressions columns of steel reinforced recycled concrete columns test data,the traditional steel reinforced concrete structure calculation theory and related design codes in China were used to investigate the ultimate bearing capacity calculation of steel reinforced recycled concrete columns.The results showed that:the code of JGJ 138--2001 could be applied to calculate the ultimate bearing capacity of steel reinforced recycled concrete eccentric columns ,the traditional steel reinforced concrete structure calculation theory wasn't suitable for axial compression calculation, and yet the YB 9082--2006 don't apply to calculate eccentric compression, its calculation results were less than the experimental results, could not ensured the safety of structure.In the end, the practical calculation formula was put forward,the results offer reference to engineering application on steel reinforced recycled concrete composite structure.
