PREDICTION OF COLLAPSE LOADINGS FOR COMPOSITE HIGHWAY BRIDGES

A THEORETICAL AND EXPERIMENTAL INVESTIGATION INTO THE COLLAPSE BEHAVIOR OF SINGLE-SPAN, SIMPLY SUPPORTED, SKEW, COMPOSITE STEEL GIRDERS AND DECK SLAB HIGHWAY BRIDGES IS DESCRIBED. A LOWER BOUND SOLUTION IS DEVELOPED USING THIN PLATE, SMALL DEFLEXION, ELASTIC-PLASTIC STIFFENED PLATE THEORY. DYNAMIC RELAXATION AND LOAD INCREMENTATION ARE USED TO SOLVE SETS OF FINITE DIFFERENCE EQUILIBRIUM EQUATIONS. RESULTS ARE COMPARED WITH THOSE OBTAINED FROM AN UPPER BOUND YIELD LINE ANALYSIS AND FROM TESTS ON TWO ONE-SIXTH SCALE MODELS. /AUTHOR/
