The gabled lean-to mill bent is an irregular rigid frame. The classical methods, e. g., the method of least work, slope-deflection, etc., for the analysis of the rigid frame are too tedious to be accepted, because they are not only dependent on the solution of simultaneous equations, but also the difficulty in establishing the equations. The method of moment distribution for computing the stresses of the same structure is also tedious because there are a great number of joint rotations and displacements...

The gabled lean-to mill bent is an irregular rigid frame. The classical methods, e. g., the method of least work, slope-deflection, etc., for the analysis of the rigid frame are too tedious to be accepted, because they are not only dependent on the solution of simultaneous equations, but also the difficulty in establishing the equations. The method of moment distribution for computing the stresses of the same structure is also tedious because there are a great number of joint rotations and displacements involving in the gabled lean-to mill bents.A new method, symmetry-antisymmetry method, for computing the stresses in symmetrical gabled lean-to mill bents is presented in this paper. The foundamental conception of this method is to determine the shape constants and load constants of the unsymmetrical Γ-shaped frame as a whole and to treat it as a single member in the analysis.

關於披屋廠房排架的應力分析,目前已有不少切實可行的方法。但以這類排架內部組織的特殊,一般通用的基本方法,多不能為實際工作者赢得時間和精力的充分節約。本文目的,在提供一個分析對稱式斜頂披屋廠房拂架的簡便方法,予以適當修正,並可推廣應用於其他各種類型的披屋廠房排架。本法的主要特點是將排架中具有“Γ”形的曲桿當作一個基本構件,從而求出這個基本構件在兩端結點角變和位移以及荷載作用下的“形常数”與“載常數”;並將不對稱荷載件成“對稱的”與“不對稱的”兩種情形,使在分析計算過程中必須考慮平衡的結點數目诚至最少程度。

This paper discusses some problems which are found to be important in designing the arch dam of the Liv-Hsi-Ho-hydroelectrical power station. The arch dam under discussion has a max. height of 82 m and spans 255. m, situated in a V-shaped valley. It is an overflow arch dam of the various radius and thickness type. The technical design has been nearly finished and the dam is now under construction. The first problem discussed is the investigation of the stability of arch dam under various ioads when the dam is rested on a rock foundation with unexpected jointe and cracks. Methods and formulas for the determination of stability factors are recommended. Then the paper reviews the various methods of stress andlysis of arch dams now in use and finds that the cantilever-arch method (or so called the trial load method) is a suitable one. An amphified procedure is suggested, with this procedure and by means of certain tables of founda- tion and arch deformation constanis, the analysis of stressos and deflections of a circular arch including the effect of foundation deformation can be simplified greately without sacrifyinq dccuracy. The necessdry tables needed in analysis will be presented in an dnother paper. The problems of temperature control and temperature stresses determination are also impor- lant ones in arch dam design and construction. This paper discusses the vdrious principles of temperature control and method of computation, and describes the one accepted in this dam. The priciples of analysis of temperature stresses of arch dams are discussed in detail. Finally the problem of discharginq floods over the arch dam is described in brief. The design work in this respect has not been finished, further investigations and model tests are roquired.

本文旨在论述流溪河拱壩工程在设计中一些主要问题。拱壩最大壩高82公尺,壩顶弧长255.5公尺,位于一V形山谷中。壩体大不同半径和厚度拱壩并采用壩顶溢流形式。工程设计及施工已接近完成。本文首先探讨了拱壩壩头岩基具有节理和裂隙时在不同荷载下的稳定问题。推荐了决定系数的方法和公式。其后就现有的拱壩各种放力分析方法进行了论述并认力悬臂拱法(或称试载法)较为适用。本文对于试载法提出了改进步骤,利用这些改进步骤并借用一定数量的基础和拱圈变形常数表则计算应力分析和包括基础变形的圆拱变位可大大简化并无损其精度。在分析中所需数表将另著文介绍。控制拱壩温度和确定温度应力问题在拱壩设计和施工中也极关重要。本文论述了温度控制的各种原理和计算方法,并描述了本工程所采用的措施。对于拱壩温度应力的分析原理曾加论述。最后曾就拱壩壩顶溢流问题加以简述。有关此项新颖问题的设计,需待进一步研究并进行模型试验。

At a result of a theotetical analysis of the elastic, ability of shell, it is shown that when the effect of the restraint on the edges can be ignored, the buckling stress of a shell may be determined with the aid of the following formula: where Te is the total compresive stress in the direction θacting on a unit-length section of the shell Rθ+π/2, is the radius of curvature of the shell along the section; δis the thickness of the shell E is the modulus of elasticity of the material, and μis the poi-...

At a result of a theotetical analysis of the elastic, ability of shell, it is shown that when the effect of the restraint on the edges can be ignored, the buckling stress of a shell may be determined with the aid of the following formula: where Te is the total compresive stress in the direction θacting on a unit-length section of the shell Rθ+π/2, is the radius of curvature of the shell along the section; δis the thickness of the shell E is the modulus of elasticity of the material, and μis the poi- sson's ratio. The condition under which the effect of the edge restraint can be ignored is that where le is the span of the shell in the direetion θ. Some examples in which boundary condition have to be considered have been worked out, and the results are compared with the known results. Finally, an approximate expression is proposed for the tangential modulus of ela- sticity of the materiad, to thet the results of the present analysis can be extended to cover the elastic plastic region. A formula for use in practical structural calcu-lations is also given

弹性稳定理论分析的结果表明,当周边约束的影响可不考虑时,一般双曲薄壳的临界内力可按下式决定:式中:Te-壳体在θ向的单位长度截面上的计算(压)内力;-壳体中曲面沿截面走向的曲率半径;δ-壳体厚度.E-材料弹性模数,μ-巴桑比数. 周边约束影响可不予考虑的条件如下:式中le为壳体在θ向的跨度. 文中在分析了若干个在其中边界约束的影响必须于以考虑的例子,并将结果与已知结果作了比较. 最后,作者建议采用材料正切弹性模数的近似表达式,以便将分析结果,推广到弹塑性范围,并提出了结构计算中的实用公式.
