This paper studies the geometrieal non-Linear problem of a stiffened plate and shell structure by the finite element method. The discrete elements used are triangular plate elements and beam elements. Both stresses due to the axial action of the beam and the membrane action of the plate are considered. Comoving coordinate system and incremental process are adopted and the effect of large deflection on loads is also discussed.

For the membrane stress state the constant strain element (the displacement function is the linear function of cartesian coordinates) is used and for the heading stress state the constant curvature element (the displacement function is the cubic function of the area coordinates)is used.

The stress of the connective part of the thin-wall beam system is analysed by the finite element method. In the analysis,the connective part is divided into many triangular plate elements. For the membrane stress state the constant strain element (the displacement function is the linear function of cartesian coordinates) is used and for the heading stress state the constant curvature element (the displacement function is the cubic function of the area coordinates)is used. Then,as a shell the connective part is computed. A node of the plough frame (the connective part that consists of the beams with box section) and a node that consists of the beams with channel section are computed and analysed by this method.

To counter the rather large non-conforming error of triangular non-conforming elements,we exercise an effective control of the non-conforming error by means of putting proper restrictions on the rate of change of normal derivative at nodes and on the value of normal derivative at the center of element boundary Furthermore,we can utilize the non-conforming error to compensate for the interpolating error so that the performance of elements can be greatly improved.In this way,some simple (9 parameters) triangular plate elements with higher,accuracy are obtained.The calculations of some typical problems show that these elements have good convergent property.

本文针对三角形薄板非协调元协调误差较大的特点,通过对节点处法向导数的变化率以及单元边界中点的法向导数值加以恰当的限制,有效地控制了非协调元的协调误差,並进而利用协调误差来补偿插值误差,使单元的收敛性得到很大改善。这样,导出了一些具有较高精确度的简单(9个自由度)三角形单元。计算结果表明这些单元具有良好的收敛特性。
