It is an efficient way to study arch dams by structural model tests, especially when the valley is unsymmetrical or is surrounded with a complicated boundary. This paper describes the course of the studies of a high, double-curvature, thin-concrete arch dam by structural model tests. The dam is located on an unsymmetrical valley with steep canyon walls. Through several stages of studies and repeated modifications the dam is presented to be five-curvature. arches in the horizontal planes in order to diminish the moments of sections of the arches. Furthermore, the damsite is revised to symmetrical shape both by excavating the left abutment and by constructing massive concrete plugs on the right abutment. The analyses of model tests have confirmed that it is a proper way to modify effectively the stress distribution on the dam to a better state-with no tensile stress and more uniform distribution of compression stresses, so as to permit very efficient structural utilization of the strength of concrete in the dam. The external water load acting on the crown cantilever are checked by the shell theory from the stresses which are measured on the model. The results are well satisfactory.

It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement...

A general theory for snap-through buckling of an open bimetallic shallow spherical shell under uniform temperature field is presented in this paper. It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement with earlier work by Wittrick.According to the selection of reference surface of coordinates as suggested by and Radkowski, the basic equations for a double-layered shell are first simplified in forms similar to those of classical shell theory. By analogy, the thermal effect is replaced by an equivalent edge-moment loaded uniformly along both boundaries of the shallow spherical shell. The problem is then solved according to Hu's simplified method, but with some vital modifications. From the results of numerical computations, the paper gives some rather interesting conclusions, which may be valuable in designing the elastic elements of various instruments in engineering.

本文提出了有关开顶双层金属球面扁壳在均匀温度场作用下的稳定性的一般理论,它给出临界跳跃温度与壳体的物理、几何诸参数之间的相互关系,包括其开顶牛径大小也作为一个重要因素.文中并将它们绘成相应的实用曲线.在封顶球面扁壳的简化特例情况下,新理论似与早期wittrick的计算结果趋近一致. 根据与Radkowski建议的坐标参考面的选择方法,我们将双层壳体的基本方程首先简化成与经典壳体理论相似的形式.再通过比拟,以作用于球面扁壳内外边界上的均匀分布的相当边界力矩来替换温度效应.然后采用文献[6]的简化方法作了必要的改进来求解方程.从数值计算的结果,文中给出了一些有趣的结论,它们对于工程上各种仪表弹性元件的设计具有一定的参考价值.

Giving up the hypothesis of σ_(γγ)= e_(γγ)= e_(αγ)= e_(βγ)=0, which is the well- known hypothesis of indeformable normal of shell surface as usually adopted by the current shell theories, this paper presents a new theory on thermal stresses in shells. Considering the effects of stress σ_(γγ), the stress normal to shell surface due to temperature, some basic relations were derived here for arbitrary shape of shcll. Theyare (1) thermal elastic relations. where and θ_o and θ_i are the temperature increment at outside and inside of the shell. (2) equilibrium equations By these relations derived here, we analyzed the thermol stresses in shallow shell for different temperaturc distributions. Consequently, the cooresponding thermal stresses in circular cylindrical shell and plate were obtained. According to this theory the basic equation for plate in the case of μ=0 is ▽~4w-ξ▽~2θ_d-3/h~2ξθ_d =0 while the corresponding equation according to the current theory is ▽~4w-ξ▽~2θ_d=0. Comparing these two theories, we find that the results obtained by the current theory is much smaller than this theory in the case of sinusoidal distribution of θ_d.

关于壳体中的热应力,抛弃了目前壳体理论中的“不变法线”假说,这里提出的理论使我们可以较为正确地来认识壳体中热应力的变化规律。
