Behaviour of hollow section connections under seismic loading


The seismic performance of square hollow section welded connections, including both hot rolled and cold rolled steel, with both traditional X-joints and bird-beak joints, was studied. The joints were subjected to quasi-static inelastic cyclic loading. The bird-beak joints generally exhibited superior performance compared with the traditional joints, by: dissipating more energy; maintaining strength after fracture; and having greater first yield displacements. Fracture was predominantly ductile. 4 refs.
