Cyclic behaviour of beam-to-column weled connections

Elena Mele(Italy), Luis Calado(Portugal) and Antonello De Luca(Itlay)

Abstract

In this paper the results of an experimental program devoted to the assessment of the cyclicrnbehaviour of full scale, European type, beam-column subassemblages with welded connections are presented.rnSix tests (five cyclic and one monotonic) have been carried out on three different series of specimens,rnencompassing a total of eighteen tests. The three specimen series have been designed with the aim of definingrnthe effect of the column size on the connection behaviour, under different applied loading histories. The testsrnhave evidenced the effect of the column size and panel zone design and of the applied loading history on therncyclic behaviour and failure modes of the connections.

Key Words

welded connections; cyclic tests; loading histories; rotation capacity; panel zone;failure modes.
