A FINITE-ELEMENT METHOD OF ANALYSIS FOR COMPOSITE BEAMS

A METHOD OF ANALYSIS FOR COMPOSITE BEAMS WITH ANY DEGREE OF HORIZONTAL SHEAR INTERACTION IS PRESENTED. THE METHOD IS VERY VERSATILE. IT IS APPLICABLE TO COMPOSITE BEAMS THAT HAVE ABRUPT, POINT-BY-POINT, VARIATIONS IN THEIR STRUCTURAL PROPERTIES. ALSO, THE BEAM MAY BE SUBJECTED TO ANY CONFIGURATION OF TRANSVERSE OR LONGITUDINAL LOAD, AND IT MAY BE SUPPORTED IN ANY REASONABLE MANNER. THERE ARE THREE IMPORTANT FEATURES IN THE METHOD OF ANALYSIS PRESENTED. FRIST, A FINITE-ELEMENT MODEL IS SUBSTITUTED FOR THE REAL STRUCTURE. SECOND, ALGEBRAIC EQUATIONS WHICH DESCRIBE THE LOAD-DEFLECTION BEHAVIOR ARE WRITTEN FOR THE MODEL. FINALLY, THE EQUATIONS ARE SOLVED FOR THE UNKNOWN DEFLECTIONS BY A MODIFIED FORM OF GAUSSIAN ELIMINATION. THE SOLUTION OF PRACTICAL PROBLEMS IS FACILITATED BY THE USE OF THE COMPUTER PROGRAM, COMBM 1, WHICH UTILIZES THE METHOD OF ANALYSIS PRESENTED HEREIN. A SERIES OF EXAMPLE PROBLEMS ARE INCLUDED TO DEMONSTRATE THE USE OF THE PROGRAM AND THE GENERALITY OF THE METHOD. /AUTHOR/
