SUSTAINABILITY OF CENTRALLY COMPRESSED RIBBED WALL PANELS
The problem of the stability of the plate consisting of two sheathing and regularly spaced to the vertical edges glued to the sheathing is solved. The sheathing are made of wood-based materials, and the ribs are made of boards. In the problem, the stability of the plate is common and local - for a single cell of the panel. The paper presents the optimal case of a ribbed plate, when local and general loss of stability is achieved simultaneously. The method of calculating the task, which allows it make the optimal design of a ribbed panel in a certain range of changes in the geometric and mechanical parameters of the panel elements, is considered.
