Behavior and Strength of Headed Stud–SFRCC Shear Connection. I: Experimental Study
The performance of a single-headed stud and group of studs embedded in steel-fiber-reinforced cementitious composites (SFRCC) were investigated by conducting push-out tests. A total of 16 specimens were tested with various parameters including diameter of studs, numbers of studs, gauge lengths, pitch lengths, and fiber volume fractions of SFRCC. The test results showed that the headed studs embedded in SFRCC ensured the failure mode of stud fracture even without using steel rebar in the slab. The studs densely arranged with the smallest pitch length permitted for installation provided more than 90% of the full shear strength of a single stud. Using nine studs densely arranged in an area allowing for only four studs in the current design code, the overall shear resistance was twice that of the conventional design. When the fiber volume fraction of SFRCC directly affects the ductility of the stud, it was found using a fiber volume fraction of 6% is most suitable.
