Abstract

Experimental results of double angle connections with thermally-induced loading are presented in this paper. Two beam assemblies were tested inside a furnace by simulating typical building fire conditions. These beams were connected to a restrained steel frame outside of the furnace with double angle connections. The test variables included fire scenario, load level and composite action arising from beam-slab effect. Data generated from the fire tests indicate that double angle connection exhibit inherent rotational rigidity in spite of being designed as simple shear connections and are capable of transferring thermally-induced moments. Despite undergoing permanent deformations, no failure occurred in the tested assembly, thus illustrating the ductile behavior of the double angle connections.
