Abstract

Theoretical analysis to average crushing load of the two multi-cell square structures are built using the Simplified Super Folding Element (SSFE) theory. The structures’ profiles compose of several basic angle elements: right corner, T-shape, 3-panel, and criss-cross angle element. Finite element analyses (FEA) are performed for these structures and point out that the structure I is the best structures. For two structures, the stable and progressive collapse are generated. The theoretical solutions are used to validate the FEA results.
