Rigidly-jointed truss beam-columns which are composed of rectangular tubes by welding have the high strength of the lateral-torsional buckling, and can be more easily fabricated than trusses composed of circular tubes. However, the web members may cause local deformations in the flat plate elements of rectangular tube chords around the connections, which might reduce the buckling strength. From this point of view, experimental and theoretical investigations have been carried out. The paper presents the results, and then gives a more rational and economical design method instead of conventional methods which neglect the advantages of tubes.
