Abstract
Push-out test is popular method to obtained the shear strength of headed stud shear connector. However, the push-out test's results depend upon the symmetry of the specimen and the loading system. We investigate on standard push-out test method for headed stud shear connectors, to take notice of the slip rigidity and the shear strength. The width of concrete slab and the stairs of headed stud shear connectors are effective on the mechanical properties of headed stud shear connectors. In case of the uniform thickness of concrete slab, the standard push-out. test method is proposed as follows. ? The stairs of headed stud shear connectors is one. The width of concrete slab is over 400mm.
