摘要
对8根十字形截面钢筋砼构件在轴向力及双向弯矩共同作用下的反复加载试验研究,揭示了十字形截面钢筋砼双向压弯构件的破坏形态及正截面承载力的一般规律。在此基础上,采用数值迭代方法,编制了相应的电算程序,对其受力性能做了进一步的理论分析,提出了十字形截面钢筋砼双向压弯构件正截面承载力的计算方法。
Based on the experimental study of & R. C. short columns with ' +', shaped cross section subjected to axial compression and cyclically biaxial bending, this paper reveals the failure pattern and general regularity for load-bearing capacity of the columns. The theoretical analyses result using the digital iteration method and the design procedure of load-bearing capacity behavior for the R. C. columns are proposed.
