A new structural connection with special unique features was developed. While under bending it showed very high rotational capacity, in shear, unlike other existing connections, it also demonstrated a large shear deformation capacity. The ductile response of this connection stems from its innovative geometry as well as the ductility of the elements embedded in it. Since the previous shear tests on the specimens of this connection were carried out under ‘unrestricted’ conditions, the tests reported here were all under ‘restricted’ conditions. These shear tests consisted of ‘monotonic’ as well as ‘cyclic’ tests on mild steel specimens. Due to the restrictions imposed on the specimens during the test, the stiffness increased, compared with that of their unrestricted counterparts. Also, the transition from shear phase to tensile phase of deformation took place at an earlier stage compared with its non-restricted counterpart. The monotonic tests proved the high shear deformation capacity of the connection which exists alongside its high stiffness as well as strength. The cyclic tests, however, showed the large number of hysteresis cycles the specimens could endure before failure. Both types of tests, monotonic and cyclic, proved the ability of the connection to dissipate energy in shear under either loading regime in a very efficient manner.
