THE PREDICTION OF CRACK WIDTHS IN REINFORCED CONCRETE BEAMS

TWO PARAMETERS, CONCRETE COVER AND AVERAGE EFFECTIVE AREA OF CONCRETE SURROUNDING EACH BAR, WERE VARIED IN A FACTORIAL EXPERIMENT ON RECTANGULAR REINFORCED CONCRETE BEAMS. CRACK WIDTHS WERE MEASURED FROM FULL-SCALE PHOTOGRAPHIC PLATES TAKEN OF THE TENSILE REGION FOR THE SERIES OF NINE BEAMS LOADED TO A SELECTED STEEL STRESS. COMPARISONS ARE MADE BETWEEN THE OBSERVED MEAN AND MAXIMUM CRACK WIDTHS, PREDICTED VALUES FROM PREVIOUSLY SUGGESTED FORMULAE, AND A NEW FORMULA PROPOSED BY THE AUTHORS WHICH INCORPORATES THE TWO PARAMETERS VARIED TOGETHER WITH THE AVERAGE CONCRETE STRAIN AT THE LEVEL CONSIDERED(A).
