我们在采用连续迭代法进行框架结构计算中发现,这种单一、重复、有时是冗长的过程,具有无穷级数的形式,因而设想采用无穷级数和的办法来直接确定杆端最终弯矩,获得初步成果,提出了以“调整节点不平衡弯矩”为基础的方法,采用“不平衡计算弯矩”来直接求得各杆件最终弯矩的《弯矩直接分配法》。近年来,通过几个工程的试用对比,提高了工作效率。 In the calculation of the frame structure using the continuous iteration method, we found that this single, repetitive, and sometimes lengthy process has the form of an infinite series. Therefore, we use the infinite series method to directly determine the final bending moment at the rod end. Obtained preliminary results and proposed a method based on “adjusting the unbalanced bending moments of the joints” and using the “unbalanced calculation of bending moments” to directly obtain the “moment direct distribution method” of the ultimate bending moment of each member. . In recent years, through the trial comparison of several projects, the work efficiency has been improved.
