正交异性劈锥面扁壳屋盖的计算

本文介绍工业建筑中常用的正交各向异性劈锥面扁壳屋盖的计算.由于该劈锥面扁壳的中曲面存在变曲率和扭率,故所得的基本方程组是变系数的,欲得到精确的解析解在数学上有很大的困难.本文用小参数法求出在均布载荷作用之下,四边简支的正交各向异性劈锥面扁壳屋盖的近似解答.

Calculation of Orthotropic Shallow Conoidal Shell Roofs

The present paper is to introduce the method for the calculation of the roof with orthotropic shallow conoidal shells which are always used in the industrial buildings. Since the middle surface of the shallow conoidal shell having the variable curvatures and twists, therefore the system of fundamental equations, which are obtained by us, are being possessed of the variable coefficients.If we want to find the exact analytical solutions, it will be involved in great mathematical difficulties. This paper gives the approximate solutions of the orthotropic shallow conoidal shell roof which is simply supported at all edges and under the uniformly distributed load. In this paper the method of small parameter is used.
