AN EXPERIMENT STUDY OF THE USE OF HIGH-STRENGTH FRICTION GRIP BOLTS AS SHEAR CONNECTORS IN COMPOSITE BEAMS

EXPERIMENTS WERE CONDUCTED ON THE USE OF THE HIGH STRENGTH FRICTION-GRIP BOLT TO PROVIDE THE SHEAR CONNECTION BETWEEN THE CONCRETE SLAB AND STEEL BEAM IN COMPOSITE CONSTRUCTION. STATIC PUSH-OUT TESTS WERE MADE TO DETERMINE THE STRENGTH OF SUCH CONNECTORS. TESTS WERE ALSO MADE ON BEAMS, SOME WITH PRECAST AND OTHERS WITH CAST-IN-SITU SLABS USING THEM. THE RESULTS SHOW THAT THE HIGH-STRENGTH FRICTION-GRIP BOLT CAN BE USED AS AN EFFICIENT CONNECTOR IN COMPOSITE CONSTRUCTION. /RRL(A)/
