摘　　要：基于渐近法的基本思想,提出了一种计算杆系结构的简便方法:力矩-剪力分配法。该法利用弯矩剪力转换系数和剪力弯矩转换系数,不断将结点不平衡力矩和不平衡力交替进行分配与传递,使杆系结构的杆端力逐渐逼近于精确解,具有渐近法的各种优点,适用于各种由梁柱组成的刚架结构的计算。A new method to calculate the beam-system structure is put up based on the idea of asymptotic method.According to the basic thought of general asymptotic methods as well as translating coefficients between moment and shear,the unbalanced moment and the unbalanced force at joints are distributed and conveyed alternately.The end forces in the beam-system structure tend to accurate solution.Moment-shear distribution method not only has various advantages over asymptotic methods,but also good for calculation of all sorts of frame structures which are composed of beams and columns.
