最近顾翼鹰同志在土木工程发表了[1]、[2]、[3 ]三篇论文,内中都叙述了他所创的“直接剪力分配法”与其各种应用。笔者觉得这个近似法既不精确又不简捷,远较许多其他方法为逊。无论在理论上与应用上这个方法都没有什么价值。按照此法,杆端挠短系逐阶段地考虑上下层的挠矩影响而得。倘理论上完全可靠,则每进行一个阶段的计算,结果必定更趋精确,即必须逐步近似;但在该法事实上并非如此。即以
Comrade Gu Yiying recently published three papers [1], [2], and [3] in civil engineering. Both of them describe the “direct shear distribution method” he created and its various applications. The author believes that this approximation is neither precise nor straightforward, and is far less powerful than many other methods. There is no value in this method, both theoretically and practically. According to this method, the rod end flexure system is obtained by considering the influence of the upper and lower layer bending moment by stage. If theoretically completely reliable, the result must be more precise for each stage of the calculation, ie it must be gradually approximated; but in fact it is not the case in this law. Ie
