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...

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。

In the engineering constructions the orthotropic continuous rectangular plates are often used. For instance, in a reinforced concrete building, the floor system consists of continuous rectangular plates supported by cross beams, and in ship building we often use the continuous rectangular glued plates. In analysing the stresses, theory which is derived for continuous isotropic rectangular plates is adopted. The results obtained is evidently different from the actual state, because the distribution of stress is much effected when the plate has different elastic properties in different directions, In this paper is presented a method of calculation, which takes into account the orthotropic properties of the materials. The results thus obtained will certainly much better approximate to the reality than when the classical theory is used. This paper contains the following items: 1. The bending of orthotropic continuous rectangular plates under loads normal to the plate. 2. The bending of orthotropic continuous rectangular plates under loads normal to the plate together with tensile forces acting in the plane of the plate. 3. The bending of orthotropic continuous rectangular plates under loads normal to the plate together with compressive forces acting in the plane of the plate. 4. The bending of orthotropic continuous rectangular plates. on elastic foundation. 5. The elastic stability of orthotropic continuous rectangular plates 6. The vibration of orthotropic continuous rectangular plates. For the first four items, we get a governing equation which connects the bending moments above three successive supports. For example, for the third case, we have: Several mumerical examples are included to illustrate the thoretical results obtained.

各向异性连续矩形板是常用的一种工程结构。例如在钢筋混凝土房屋建筑物中,楼板部份即是由交叉梁支持的连续矩形板构成的,在船舶构造中亦广泛应用着腰合的连续矩形板。在分析应力时,常应用迦遼金由各向同性连续矩形板所导出的理论,但其结果与实际情况很有出入,因为当在板的不同方向具有不同弹性性质时应力的分布即受到影响,本文提供一种考虑材料各向异性性质的计算方法。其所得结果较用古典的迦遼金理论当更接近实际情况 本文包括下列诸部分: (1)在垂直于板面的荷载作用下正交各向异性连续矩形板的弯曲; (2)在板平面内有张力及垂直于板面的载荷共同作用下的正交各向异性连续矩形板的弯曲; (3)在板平面内有压力及垂直于板的荷重共同作用下的正交各向异性连续矩形板的弯曲; (4)在弹性地基上的正交各向异性连续矩形板的弯曲; (5)正交各向异性连续矩形板的稳定; (6)正交各向异性连续矩形板的振动, 对于前四部份,本文作者得出了三弯矩方程式。文中并列举了数字例子。

大桥支撑系的合理计算是目前还没有得到解决的问题。我们为此选定武汉长江大桥[1]的断面支撑系为例进行了模型试验。模型是用有机玻璃作成的。用电阻丝测得模型在荷载下的各杆件的应力,并对实验结果进行了分析研究。实验结果证明,在竖直荷载作用下,断面支撑系杆件所受内力很大,因此,对断面支撑系的计算问题,提出了初步意见,并对今后研究工作,提出建议。
