Beam-column joint connected with thin-walled cold-fonned steel members used in middle rise building stmctures is studied. In order to study the properties of this kind of beam-column joints under the low reversed cyclic loading, such as failure state models, defonnability, ductility energy dissipation, stifirness reduction, the low reversed cyclic loading tests of 6 beam-column joints have been performed with two types of steel (Q235 and lOPCu-Re), three kinds of column wall tluckness, and the results of tests and the discussion are presented.
