SHEAR AND ANCHORAGE STUDY OF REINFORCEMENT IN INVERTED T-BEAM BENT CAP GIRDERS

BEAMS CONSTRUCTED WITH A CROSS SECTION IN THE FORM OF AN INVERTED T POSSES ON EACH SIDE OF THE WEB FORM A SHELF THAT PROVIDES A CONVENIENT SUPPORTING SURFACE FOR PRECAST MEMBERS. INVERTED T-BEAMS ARE FINDING FREQUENT USE AS BENT CAP BEAMS TO SUPPORT STRINGERS. THE APPLICATIONS OF LOAD TO THE LOWER PORTIONS OF CONCRETE BEAMS CREATE TENSILE FORCES NOT ORDINARILY ENCOUNTERED IN CONCRETE CONSTRUCTION. REINFORCEMENT FOR THE FLANGES OF THE T PRESENTS SPECIAL PROBLEMS REGARDING THE SHEAR STRENGTH, THE ANCHORAGE OF BARS, AND THE FLEXURAL BEHAVIOR IN THE FLANGE OR SHELF. TWENTY-FOUR LOAD TESTS WERE CONDUCTED ON SIX INVERTED T-BEAM SPECIMENS, IN ORDER TO STUDY REINFORCEMENT DETAILS, BEHAVIOR, AND MODE OF FAILURE. THE RESULTS OF THESE TESTS HAVE BEEN COMPARED WITH APPROPRIATE GENERAL THEORIES AND ANALYTIC ESTIMATES, AND RECOMMENDATIONS HAVE BEEN MADE FOR THE DESIGN OF SUCH MEMBERS. /AUTHOR/
