摘　　要：提出逐级加载、待定系数的方法计算钢筋混凝土双向受弯梁的次生扭矩,编制钢筋混凝土双向受弯梁的次生扭矩全过程分析的计算机程序。通过计算分析,探讨了次生扭矩对抗剪承载力的影响。计算值与试验结果的对比分析表明,该文所提出的方法合理可行。Introduced here is the application of progressively loading with infinitive coefficients to calculate the secondary torsion moment of reinforced concrete bi-flexural beam and program the analysis of the process for it, as well as the discussion on effect on shearing strength exerted by secondary torsion moment after computation & analysis. Comparison and analysis of calculation results and testing results show that the method introduced above is feasible.

关 键 词：钢筋混凝土 双向受弯梁 次生扭矩 截面转角 抗剪承载力
