Abstract

Studs with large diameter and high strength have been used in many composite structures, but the former research results were mainly based on middle or small diameter studs with normal strength. 12 push-out tests on stud connectors with different diameters and strengths were performed. The results show that the shear resistance and shear stiffness of studs with large diameter and high strength are all higher than the normal stud connectors used before. The experimental results were also compared with the calculated results based on the formulas from many countries´ design codes. It seems that these formulas are all conservative and can be used to calculate the shear resistance of studs with large diameter and high strength.
