| Summary: | A new stud system fastened with high strength pins was investigated experimentally in this paper. This system is reported to be the fastest and the most economical method for installing studs to steel roof and floor decking in composite construction. It is 5-10 times faster than welding, screwing, or using powder actuated tools, which will directly reduce the fastening cost. These advantages would make significant contribution to the popularity of composite construction. The shear capacity of headed studs in composite steel-concrete beams has been determined experimentally in seven full-scale push-off tests. The tests were used to study the strength and ductility of the proposed stud system. Maximum resistances from the experimental tests are compared with the predictions of EC 4 and results from other researchers. The capacity of the stud is reduced due to fracture of the pins that occur before the shear stud had yielded. The proposed stud system can be improved further by increasing the size and the strength of the pins and base plate. |
