我读了袁啸楚同志在土木工程学报1960年第1期上发表的“无筋扁壳理论及其应用”一文后,很感兴趣,这里提出自己一些粗浅的意见。 1.关于矩形扁壳的曲面方程 在袁啸楚同志的文章中(以下简称原文),提供了四边边界上竖标z=0的矩形扁壳的计算表格和按狄里克雷问题的差分解法,来解决其他边界条件下壳体的计算问题。采用表格计算虽简捷,但却受边长比的限制,用差分法和三角级数法则较繁琐,因而这
I read Comrade Yuan Xiaochu’s article “The Theory and Application of Flattened Shells” published in the 1st issue of the Civil Engineering Journal, 1960, and I was very interested. Here I give some rough ideas. 1. About the curved surface equation of a rectangular flat shell In the article by Comrade Yuan Xiaochu (hereinafter referred to as the original), the calculation table of rectangular flat shells with z=0 on the four sides of the boundary and the differential decomposition method according to the Dirichlet problem are provided. Solve the problem of shell calculation under other boundary conditions. Although the use of table calculations is simple, it is limited by the ratio of side lengths. Using the difference method and the trigonometric series method is more tedious.
