COMPUTER PROGRAM FOR BRIDGES ON FLEXIBLE BENTS

A COMPUTER PROGRAM IS PRESENTED FOR THE ANALYSIS OF PRISMATIC FOLDED PLATE STRUCTURES WITH FLEXIBLE INTERIOR DIAPHRAGMS OR SUPPORTS. THE SOLUTION IS BASED ON A DIRECT STIFFNESS HARMONIC ANALYSIS INCORPORATING A FORCE METHOD TAKING THE INTERACTION FORCES BETWEEN THE FOLDED PLATES AND DIAPHRAGMS OR SUPPORT BENTS AS REDUNDANTS. THE STRUCTURE IS CONSIDERED AS AN ASSEMBLAGE OF RECTANGULAR PLATE ELEMENTS INTERCONNECTED AT LONGITUDINAL JOINTS AND SIMPLY SUPPORTED AT THE TWO ENDS. THE APPLIED FORCES ARE RESOLVED INTO FOURIER SERIES COMPONENTS. A DIRECT STIFFNESS ANALYSIS BASED ON CLASSICAL THIN PLATE BENDING THEORY AND PLANE STRESS ELASTICITY THEORY IS CARRIED OUT FOR EACH HARMONIC. THE INTERACTION FORCES ARE DETERMINED BY SATISFYING THE REQUIRED COMPATIBILITY CONDITIONS. THE FINAL RESULTS ARE OBTAINED BY SUMMING THE SOLUTIONS FOR THE KNOWN LOADING AND THE REDUNDANT FORCES. /AUTHOR/
