承重预制墙是装备式房屋的主要构件，它是在周界用一个框架加固的一块矩形薄板。作用的荷重系加在框架上，问题就在于分析板与框架内的应力。所提供的解法为：在板内满足双调和方程的基础上，运用整个系统的变形能为最小这条件，来满足板与框架在联结线上各点的位移相一致的条件。这样就得到了一系的无穷联立方程，从而决定应力的值。本文共讨论了两种荷重的形式：一是有四个集中力各作用在框架各边的中点，一是有集中力作用在框架的角点。
The load-bearing prefabricated wall is the main component of the equipment house. It is a rectangular sheet reinforced with a frame at the perimeter. The load on the frame is added to the frame. The problem lies in analyzing the stresses in the plate and frame. The solution provided is: on the basis of satisfying the biharmonic equation in the plate, using the condition that the deformation energy of the entire system is the minimum, the condition that the displacements of the plate and the frame at the respective points on the connecting line are consistent. This results in a series of infinite simultaneous equations that determine the value of the stress. This article discusses two forms of load: First, there are four concentrated forces acting on the midpoints of the sides of the frame. One is that there is a concentrated force acting on the corners of the frame.
