Many methods of analyzing statically indeterminate structures are now available. The method of redundant forces and that of deformations (i. e. the slope-deflection method), heretofore generally used in the U. S. S. R., both require the solution of a system of simultaneous simple equations. In the case of multi-storey and multi-bay bents, the large number of such equations would greatly complicate the calculation work, it being both time-consuming and liable to make mistakes. The method of moment distribution simplifies calculations to a great extent, as there is no need to solve simultaneous equations, and therefore it has been warmly received bY practical engineers. Many soviet scholars are also devoted to its study. There are, however, defects in this method, namely: (1) Should the moments obtained in the successive cycles of distribution and carrying-over prove to converge very slowly, twenty or more such cycles must be done if fairly accurate results are expected.(2) In the case of analyzing structures under various conditions of loading, while it is possible to find the influence moments by applying a unit moment at each joint as proposed by Prof. Hardy Cross, it would bequite laborious in the case of multi-storey and multi-bay bents containing a large number of members, especially when subjected to unsymmetrical loadings.For the remedy of the first defect, such Chinese scholars as Profs. Lin Tung Yen, Chao Tsu Wu, Meng Chao Li and Tsai Fang Yin have made much contribution, and the author of this paper has recently written a discussion on the two papers of the last-mentioned scholar. For the remedy of the second defect, the author is unaware of any except that mentioned below.One of the soviet scholars, Dr. P. P. Shaggin (i.e.) has suggested important improvements with regard to both these defects. For the former, he adopted a method of single-cycle distribution; and for the latter, he invented the method of successive conjugation which greatly reduces the work of calculation in finding the influence moments. The essence of these methods is well-worth studying on the part of our Chinese engineers. After an intensive study, the author of this paper thinks that, while Dr. Shaggin's methods are quite correct in principle, his methods of calculation can still be somewhat improved, as described herein, so as to be made more easily applied in practice.This paper Shaggin based upon the book, (Calculation of Multi-storey Frames by the Method of Successive Conjugation) published in 1954 by Dr. P. P. Shaggin in Leningrad, U. S. S. R., shows that, in applying a unit moment at each joint of a given statically indeterminate structure, one can easily find the influence moments at the ends of all the members, and that, after multiplying the unbalanced fixed-end moments at each joint calculated in accordance with the given external loads, by the respective influence moments, the sum of such products added to the original fixed-end moments will give at once the actual moments at each end of the members in the structure.Three notable improvements are indicated in this paper:(1) Dr. Shaggin's formula (5") on page 11 of his book, has been altered to formulas (3) in this paper. (2) For multi-storey bents, Dr. Shaggin's method of finding the conjugate moments (i. e. the influence moments) by formulas is replaced by the usual method of simple moment-distribution.(3) The author of the paper has extended the method to the analysis of multi-storey and multi-bay bents under any system of unsymmetrical loading.Of course, for structures under a single system of loading, influence moments need not be found and, generally speaking, it would be more convenient to apply the original method of moment-distribution; for a multi-storey bent, it would be better, even in this case, to modify it by applying the method of successive conjugation.The author is of the opinion that the application of the methods described in this paper, being convenient and time-saving, would be useful to the practical engineers.

本文以蘇聯學者沙金博士最近出版之“用逐次互聯法計算多層排架”一書为依據,叙述在已知超靜定結構中每一結點,施以單位力矩,可以很容易地求得各桿端的影響力矩;然後依照其所受外力荷載,求得各結点處的定端力矩,分別乘以相當的影響力矩,相加之後並加以原有的定端力矩,即得各該桿端的實際力矩。若結構承受多種多样的荷載(不問其為豎向的或平向的、對稱的或不對稱的),用此篇所述之方法以推算各桿端力矩,著者認為最便利、最省時,並且適合實際工作者之需要。

本文提出绘制竖向荷重作用下静定拱之内力图的简化方法。本文利用了新比拟(?)把计算内力公式转变为:M=M′;(1)(?)Q=Q′cos (?);(2)(?)N~2=Q~(01)~2+H~2—Q~2;(3)(?)}式中M′,Q′分别为相应的第一种比拟(?)的弯矩、切力〔见图2(B)〕;Q~(01)为相应的第二种比拟(?)的切力〔见图2〕。同时利用(3)式的关系,可以借助于简单的针规作图把N 图绘得,而不用麻烦的运算方法,使计算工作量更为减少。利用本文的简化公式及作图方法绘制拱之内力图,比较简便。对于二次抛物线拱特别有利。

现有各种地震力理论,都不考虑竖向振动的影响。这对一般较低的结构和抗拉能力很大的结构来说是正确的,但对高耸的砖石结构(如烟囱、水塔和高坝等),就缺乏充分的根据。因为地面的竖向振动有时在高耸的结构中引起激烈的纵向振动,这样产生的拉应力可能对结构的破坏起很大作用。本文对此一问题作了初步研究,利用地震反应谱曲线的概念,提出了一个比较合理和实用的计算方法。在文中举了一个烟囱作为实例,计算结果表明纵向振动所引起的拉应力使烟囱很容易在上部断裂,这符合大家所公认的实际破坏现象。
