Experimental results The ultimate load (Ptest), ultimate displacement ( Δ test), failure modes, and the load–slip curves for each tested specimen are the main obtained results from the carried out experimental push-out tests. The obtained results will be presented and discussed in details in this section. To obtain the bearing capacity of one connector (Ptest), the ultimate load carried by the two shear connectors placed on both sides (flanges) of the HEB160 steel section is divided by the number of connectors (which is two in this case). Δ test is the maximum slip recorded between the steel and concrete measured at the connector level.
