A method for the analysis of cylindrical networks is proposed in this paper. Thecylindrical network is regarded as a space structure composed of ideal hinge-connected plane trusses with transversal members riqidly connected at joints.Taking the bendingmoments of the plane trusses, the deflections of the plane trusses and the bending mo-ments of the transversal members at joints as unknowns, the following finite differenceequations are obtained: (s,z) ---coordinates of joints. M_s(z)---bending moment of plane t?uss s at z. v_s(z)---deflection of plane t?uss s at z. G_s(z)---bending moment of transversal members at joint (s, z). q_s~p(z)---functions of loads. n---number of plane trusses. E---symbolic operator. Ef(x)=f(x+1), For simply supported case, the finite trigonometric series are employed to solve theabove equations. The solutions are given in the form:where M_(sr),G_(sr), v_(sr) are constants and m is the number of panels in the longitudinaldirection. For general cases, a method for sloving the above equations are presented, whichtransforms the system of simultaneous finite difference equations into independent finitedifference equations with the result that the solutions become easier to be obtained.

柱形纲架结构已有一些计算方法。本文用差分方程求解,得到一组联立差分方程,其中以横肋结点弯矩,横肋多边的横向切线位移,从向平面梁式桁架的弯矩M_s(z)为未知数,讨论了简支情形的解及一般的解法。 文献中的计算方法,当纵向格间较多时,要解高次特征方程和一系列的联立方程,对于简支情形,本文的方法避免了解特征方程。当横向格间较少时,用一般方法,可将联立方程孤立,使计算简化。

The load-supporting wall is the main construction element of the prefabricated building now in vogue. It is, in fact, a thin rectangular plate, along the boundary of which is reinforced a frame. The loads directly act on the frame. Our problem is to analyse the stresses both in the plate and in the frame. The method of solution this paper suggests consists in using the trigonometric series together with the principle of minimum strain energy. On the basis of having satisfied the bi-harmonic equation for the plate, the requirement that along the connecting lines of the plate and the frame the displacements should be compatible is expressed by the condition that the strain energy of the whole system has to be minimum. Thus, we get a system of infinite simultaneous equations, from which to determine the necessary unknown coefficients. This article discusses two different loading conditions: the one concerns four concentrated loads at the middle of each sides of the frame, the other is for concentrated loads at each corner of the frame. From the rasults obtained, it can be known that the solution converges. very rapidly.

承重预制墙是装备式房屋的主要构件,它是在周界用一个框架加固的一块矩形薄板。作用的荷重系加在框架上,问题就在于分析板与框架内的应力。所提供的解法为:在板内满足双调和方程的基础上,运用整个系统的变形能为最小这条件,来满足板与框架在联结线上各点的位移相一致的条件。这样就得到了一系的无穷联立方程,从而决定应力的值。本文共讨论了两种荷重的形式:一是有四个集中力各作用在框架各边的中点,一是有集中力作用在框架的角点。

Schlesinger's trigonometric relations for combined static electron lenses are derived. The foci of Glaser's Glockenfeld are calculated by a 17-section approximation, the result of which is compared with their theoretical values and discussed. With the aid of parabolic axial potential distributions, two possible designs are suggested, in which the position of image remains fixed, while its magnification being changed.
