TRANSVERSE SHEAR DEFORMATION IN MULTICELL BOX BEAM BRIDGES

A THEORETICAL ANALYSIS IS PRESENTED OF MULTICELL, RECTANGULAR BOX BEAM BRIDGES WITHOUT INTERMEDIATE DIAPHRAGMS, WHICH CONSIDERS THE EFFECT OF VIERENDEEL DISTORTION OF THE DECK. THE SOLUTION IS EXPRESSED IN FOURIER HALF-RANGE SINE SERIES AND, AS SUCH, IT IS LIMITED TO SIMPLY SUPPORTED BRIDGE DECKS. THE EDGES MAY BE FREE OR ELASTICALLY RESTRAINED BY EDGE BEAMS OF KNOWN ELASTIC RIGIDITIES IN FLEXURE AND TORSION. THE EQUATIONS FOR DEFLECTION, MOMENTS, AND SHEARS ARE DERIVED AND AN ILLUSTRATIVE EXAMPLE IS INCLUDED TO SHOW THE EFFECT OF VIERENDEEL DISTORTION ON THE LOAD DISTRIBUTION CHARACTERISTICS OF THE DECK. COMPARISON IS MADE WITH CONVENTIONAL ORTHOTROPIC PLATE THEORY. /AUTHOR/
