DISTRIBUTED LOADS CREATING COMBINED TORSION, BENDING, AND SHEAR ON L-BEAMS WITH STIRRUPS

TESTS ON SEMICONTINUOUS L-BEAMS WITH STIRRUPS, UNDER DISTRIBUTED LOADS CREATING TORSION COMBINED WITH FLEXURE AND SHEAR, SHOWED GREATER LOAD CAPACITIES, AROUND 25%, THAN SIMILAR BEAMS UNDER POINT LOADS. IN THIS EVALUATION, SHEARS AND TORQUES WERE TAKEN AT A DISTANCE D FROM THE SUPPORT. DESPITE A NEGATIVE MOMENT YIELD LINE IN THE SLAB AT THE FACE OF WEB, THE FLANGE SEEMED EFFECTIVE IN RESISTING THE TORSION. THE POST-CRACKING TORSIONAL STIFFNESS DROPPED TO 3 TO 7% OF THE INITIAL STIFFNESS. STRAIN GAGE MEASUREMENTS AT THE POINT OF INFLECTION SHOWED STEEL STRESS FROM TORSION VARYING MORE NEARLY WITH TWIST ANGLE THAN WITH TORQUE ITSELF. /ACIJ&P/
