Abstract
A perfobond strip is one of the shear connectors generally used in steel-concrete hybrid structures. We have conducted the push-out test of the perfobond strip specimen whose steel plate with the perforation was embedded in the concrete block. However, it is not clear whether the results obtained from the above experiment reproduces the one of the perfobond strip in practical structures or not. In this research, we also conduct the push-out test of the perfobond strip specimen where the steel plate with a perforation is welded to the steel base plate and constructs T-shaped section or the cruciform section as used in the practical structures. In order to predict the stress transmission between the steel base plate and the perfobond steel plate, and the force distribution along the height of the steel plates, several strain gages are attached to the steel plates in the specimen. As a result, it can be seen from the experiment that the various types of the specimens employed here have different shear force-relative slip relations and shear resistances, and the horizontal stress as well as the vertical stress is produced in the perfobond steel plate.
