An approximate and rapid method for computing the stresses and shape constartts of elastic arches is presented in this paper. The fundamental idea of this method lies in the fact that the variation of the elastic area (ds/EI) of the arch with respect to x can be represented approximately by an elementary algebraic function which can be determined with but little labor. After this function is found, all necessary computations can be done by direct integration instead of the usual tedious arithmetic summation....

The fundamental idea of this method lies in the fact that the variation of the elastic area (ds/EI) of the arch with respect to x can be represented approximately by an elementary algebraic function which can be determined with but little labor. After this function is found, all necessary computations can be done by direct integration instead of the usual tedious arithmetic summation. Formulas reduced to the final forms are presented for use, and two numerical examples are given to show the practical procedure and the degree of approximation.

本文目的在提出一種求拱應力及拱常数的近似算法。主要關鍵在求出一能近似表示拱截面ds/EI變化之代數式,使各項計算均得由直接積分完成,避免分段計和,因而極爲簡便。最後結果以公式表示,其準確程度巳敷實際需要,必要時可予提高。

In this paper the direct determination of the end-moments of rigid frameswith sidesway by the method of one-cycle moment distribution will be presented.According to this method, the end-moments produced by loading and those pro-duced by sidesway need not to be determined separately and afterwards super-posed. After getting the modified frame constants of all the bar ends, wecan employ the formulas proposed in this paper to find the values of the sideswaysfrom the known fixed-end moments produced by the loading,...

In this paper the direct determination of the end-moments of rigid frameswith sidesway by the method of one-cycle moment distribution will be presented.According to this method, the end-moments produced by loading and those pro-duced by sidesway need not to be determined separately and afterwards super-posed. After getting the modified frame constants of all the bar ends, wecan employ the formulas proposed in this paper to find the values of the sideswaysfrom the known fixed-end moments produced by the loading, and than proceedto find the fixed-end moments produced by the sidesways. Then add togetheralgebraically the fixed-end moments due to loading and those due to sideswayto get the total fixed-end moments at the bar ends. Dealing with these totalfixed-end moments with the method of propagation of unbalanced moments byassuming the frame to be without sidesway, the results obtained will be the actualend-moments. This method can be applied to frames with one or more than onesidesway. Beside the description of the method and the derivation of certainnew formulas, three numerical examples are given in this paper to illustrate theapplication of the method.

本文所述为直接求有侧移刚架各杆端挠矩的一次分配法。按照此法,由于荷载与由于侧移所生的端矩,不必分开计算然后叠加。在算得各杆端修正刚构常数后,就可以用文中所建议的公式,从已知的由于荷载所生的定端力知求得各侧移值,并进而算得侧移所生的定端力矩。继在各个杆端将荷载所生的定端力矩与侧移所生的定端力矩叠加,而得各该杆端的总的定端力短。将这些总的定端力矩用不均衡力矩传播法,按无侧移刚架的分析解算一次,结果即为所欲求的实际杆端挠矩。此法可用于分析具有一个或一个以上侧移的刚架。文中除叙述算法与导算某些新公式外,尚列举例题三则,以示本法之应用。

In Chinese sea-going ships such types of altitude and azimuth tables as tables 205 or H.O. 214 are now widely used for facilitating astronomical calculations. This is justified. But some ship officers go so far as to deny the use of any other method of computing altitudes and azimuths of heavenly bodies, including fundamental mathematical methods. Meanwhile, another school of thought exists, which is to promote the use of simplified tables similar to those as prevalent in the thirtieth. This has been reflected in recent relevant magazines and even in some articles published in this journal. In this article the author briefly points out that neither of them is right. He is of the opinion that simplified tables are obsolete and that such tables as giving the results directly must be generally used. On the other hand, the author points out and analyses the serious defects which arise from the use of the latter types of existing tables. In many cases, ship officers must resort to the use of some fundamental mathematical tables. Hence, it is pointed out that Table 205 must be recompiled and at the same time the necessity that ship officers must be highly competent with the use of at least one of the best mathematical methods is emphasized. The article then goes on discussing the requirements that new tables must and can fulfill. The main points are: 1. to make azimuth tables no longer necessary. 2. To make the finding of required data simpler and much speedier. In some cases and to some extent more accurate. 3. To make the compilation more reasonable. After explaining the measures to be taken to achieve the object set forth,the author finally suggests some concrete recompilation schemes.

我国海船上现在普遍采用海道测量部书号205或美福H.O.214类型的天体高度方位表以利便于天文观测的计算。这种做法是正确的,但是有些船员认为不须要还要会用任何其它方法计算天体高度和方位包括基本的数学演算方法在内;同时另一种想法也存在,那即是提倡使用类似30年代盛行的简化表。这种想法在近来有关杂誌和本学报某些文章中皆有所反映。本篇作者认为以上两种看法都不正确。作者的意见是:简化表目前已陈旧而直接给出结果的表册应广泛应用。作者接着又指出并分析了直接给出结果的现用表册的缺点。在许多情况下船员必须使用基本数学演算的表。所以文中一方面指出书号205的天体高度方位表应予改编,而另一方面又强调船员对至少一种数学演算法应能熟练运用。文章然后讨论新编表应达到的要求。其要点为:1.可以废除一切天体方位角表;2.使得计算更加简单更加迅速,在有些情况和某种程度上更加精确;3.合理编辑。在解释了要达到这些要求,所应采取的措施后,作者最后提出一些具体编表方案。
