Abstract
Concrete slabs are integrally cast with girders or stringers (stiffening system) resulting in floor slabs, bridge decks, footers, retaining structures and others. A portion of slab between a stiffening system acts as flange and bends in unison with the stiffening system, i.e., classic T-beam action. The emphasis of this study is to determine the effective flange width, failure modes, deformability factors, pre- and post-cracking deflections and crack widths at first crack and at ultimate failure of T-beams.;Eight concrete T-beams with two different flange widths and two reinforcement configurations were tested under four point bending to study the factors cited above. Shear lag effect was established based on the strains measured along the width of compressive flange at mid-span. Based on the test results and theoretical evaluations, design equations to predict bending behavior, deflection, effective flange width and crack-widths are developed.
