Slabs without shear einforcement usually exhibit brittle shear failure when an axial force and an unbalanced moment are transferred between the column and the slab. The effect of a new typ of shear einforcement on the strength and the ductility of the connection is studied in a series of test specimens subjected to constant aial force and varying static and dnamic moment transfer. The special shear einforcement increased substantially the strength and ductility of the connections, but ultimate failure was associated with a sudden loss of moment resistance. However, the connection was still capable to resist the axial force.
