Abstract
Cyclic loading tests were carried out to investigate effects of cross sectional shapes of column geometry and weld condition on plastic rotation capacity of H-beam. To investigate the effect of column geometry, connection sub-assemblage with SHS column, H shaped column and CHS column are tested. Plastic deformation capacity of a specimen with H shaped column was superior to any other specimens. In the case of the specimen with large fusion of throat thickness direction of beam flange or with larger strength of weld than that of beam flange, the plastic deformation capacity was improved.
