A NEW APPROACH TO THE ANALYSIS OF CELLULAR BRIDGE DECKS

CELLULAR CONCRETE BRIDGE DECKS HAVE DESIRABLE AESTHETIC PROPERTIES AND BECAUSE OF THEIR HIGH TORSIONAL STIFFNESS A GOOD STRENGTH/WEIGHT RATIO. CURRENT ANALYTICAL METHODS TEND TO USE THREE DIMENSIONAL MODELS WHICH ARE RESTRICTED IN SCOPE AND ARE EXPENSIVE. TO PRODUCE A MORE VERSATILE AND ECONOMIC ANALYTICAL TECHNIQUE AN ANALOGY BETWEEN THE BEHAVIORS OF SHEAR-WEAK SLABS AND CELLULAR STRUCTURES HAS BEEN ESTABLISHED, AND A TWO-DIMENSIONAL FINITE ELEMENT SOLUTION FOR THE EQUIVALENT SHEAR-WEAK SLABS HAS BEEN DERIVED. COMPARISONS WITH RESULTS FROM EXPERIMENTAL TESTS AND FROM THREE DIMENSIONAL TECHNIQUES SHOW THAT THE PROPOSED METHOD IS SUITABLE FOR PREDICTING THE PRINCIPLE STRESS DISTRIBUTIONS IN CONCRETE BOX GIRDER BRIDGE DECKS. /ACI/
