ANALYSIS OF ORTHOTROPIC FOLDED PLATES WITH ECCENTRIC STIFFENERS

A METHOD IS PRESENTED FOR THE ANALYSIS OF ORTHOTROPIC FOLDED PLATE STRUCTURES WITH ECCENTRIC STIFFENERS. THE DEVELOPMENT IS BASED ON THE DERIVATION OF A FINITE STRIP STIFFNESS THAT COUPLES PLACE BENDING AND THE IN-PLANE ACTION DUE TO THE ECCENTRICITY OF THE RIBS. HARMONIC ANALYSIS IS UTILIZED IN CONJUNCTION WITH THE DIRECT STIFFNESS METHOD, PROVIDING A VERY EFFICIENT COMPUTER PROGRAM THAT CAN HANDLE A VARIETY OF DIFFERENT LOADINGS. AT PRESENT THE PROGRAM IS RESTRICTED TO THE ANALYSIS OF PRISMATIC FOLDED PLATE STRUCTURES SIMPLY SUPPORTED AT THE TWO END DIAPHRAGMS. /AUTHOR/
