本学报4卷4期所刊载何福照同志的“用林氏力矩一次分配法分析对称式多层单间排架的风应力……”一文,将排架各结点的侧移与角变同时考虑,比现有的“侧移叠加法”([1]-254页)或“辅助力法”须解联立方程式的计算简化得很多.采用捷克柯劳塞克(C.V.Kloucek)的倍数定理,此法可用以分析多层多间排架在风及他种荷裁下的应力.于完全符合倍数定理的排架(即在结点受有侧力时每层各结点的角变均相等)可得到精确的结果;于不完全符合倍数定理的排架,也可得到满意的近似结果.同时对于“纵向等劲式”)平行弦连框桁架的分析,此法也是现在最简便的.笔者认为这个方法的提出是在有侧移排架的分析法中大大地迈进了一大步.
Comrade He Fuzhao’s “Analysis of wind stress in symmetrical multi-story single-bay racks using the Lin’s torque one-time distribution method” published in this volume of the 4th issue of the 4th edition of this paper considers the lateral shift and the angular change of each node of the rack. Compared with the existing “Side-shift superposition method” ([1]-254) or “assisted force method”, the calculation of the solution of simultaneous equations is simplified much more. The CV Kloucek’s multiple theorem is used. This method can be used. In order to analyze the stress of multi-row and multi-row under the wind and other kinds of load, it can be obtained in a truss that completely conforms to the multiple theorem (that is, when the nodes are subjected to lateral forces, the angular changes of each node in each layer are equal). The exact result; in the case of a truss that does not exactly conform to the multiple theorem, satisfactory results can also be obtained. At the same time, for the analysis of parallel string concatenated box trusses, this method is also the simplest. I believe this The proposed method is a big step forward in the analysis of lateral displacement.
