摘　　要：采用单一调幅系数的传统方法对钢筋混凝土框架梁进行弯矩调整,难以解决工程中所有框架梁弯矩分布不均衡的问题。通过对工程实例的计算分析并结合工程实践经验,介绍了在保证所有框架梁静力平衡的前提下采用不同调幅系数调整梁弯矩的计算方法,使梁的各控制截面弯矩值分布更加均衡,使框架结构的设计更为安全、合理。It is impossible to cover all cases of reinforced concrete frame plastic design, just using statistical design method of constant factors to reach the equilibrium of moments distributed at beams. Based on calculation and analysis of the example in realistic engineering and practical engineering requirements, a feasible plastic design method is described: On the premise that all frame beams keep static balance, variable regulating factors are adopted so that the moments in every control section of beams are well-distributed.
