工程中板壳结构的一种实用计算方法

本文采用—维B3样条插值─—半离散法，建立了正交各向异性板壳结构位移和内力的统一计算式。编制的程序适用于两对这简支另两对边任意支承的正交各向异性矩形双曲扁壳、圆柱形扁壳和板；适用于集中、均布、线性荷载或其组合。算例表明该方法能有效地解决板壳的计算。

AN APPLICABLE METHOD FOR CALCULATING THE PLATE AND SHELL STRUCTURES IN THE ENGINEERING

Based on one-dimensional B3 spline interpolation-semidiscrehzation, unified calculating formulae have been developed for displacementS and forces of orthotropic thin platesand shallow shells. The written code is suitable for orthotropic haperboloidal shells, cylindricalshells and thin plates with simple supportS on tWo opposite edges, and various support conditionson the other tWo. It can deal with concentrating, distributed loads, linearly valing distributedloads and the conbinations of them. The results of four examples show that the proposedapproach is efficient in the analysis of thin plates and shallow shells.
