FLEXURAL CRACKING BEHAVIOR OF PRETENSIONED I- AND T- BEAMS

INFORMATION IS LIMITED ON THE FLEXURAL CRACKING BEHAVIOR AND CRACK WIDTH DEVELOPMENT OF PRESTRESSED BEAMS. TWENTY-TWO PRETENSIONED CONCRETE I- AND T-BEAMS HAVING A 9 FT SPAN AND PRESTRESSED WITH 1/4 IN DIAMETER 7-WIRE STRANDS ARE TESTED TO FAILURE AND THE RESULTS ANALYZED. A CRACKING HYPOTHESIS FOR PRESTRESSED CONCRETE IS PRESENTED AND AN EXPRESSION RELATING THE MAXIMUM WEIGHTED CRACK WIDTH TO THE CONTROLLING PARAMETERS IS GIVEN. /AUTHOR/
