Shear characteristics of perfobond strip with SFRM based on push-out and pull-out tests

In order to sufficiently ensure the shear performance of perfobond strip connectors in steel-concrete hybrid structures, reinforcements are generally arranged inside the connection for enhancing the restraint effect around the perfobond strip. Alternatively, the restraint effect around the perfobond strip can be enhanced by using the steel fiber reinforced mortar (SFRM) for the connection. This study aims to investigate the shear characteristics of the perfobond strip combining with SFRM in the condition without the surrounding reinforcements. The push-out and pull-out tests are carried out, and the experimental parameters are the compressive strength of SFRM, the dimensions of the perfobond steel plate and the surrounding mortar block. The influences of experimental parameters including the test method on the shear characteristics of the perfobond strip are discussed from the experimental results.
