摘要：

The relative efficiency of minimum-weight designs of waffle plates having multiple rib sizes in each stiffening direction is investigated, and compared to that of basic waffle and honeycomb- core sandwich construction. The behavior of orthogonally stiffened rectangular plates having two sets of rib sizes, and subjected to uniaxial compression, is studied in detail. Synthesis is accomplished by formulating the design requirements in terms of a mathematical programing problem, and by using a penalty function optimization algorithm suggested by Fiacco and McCormick. Results of examples indicate that a significant improvement in waffle efficiency may be achieved through incorporation of successively larger sizes of ribs at appropriate intervals, to the point where waffle construction may become competitive with sandwich construction at low loading intensities. © 1969 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
