This paper addresses the loading tests of beam-to-column connection with exterior diaphragm and circular tube column. These tests were conducted to verify the validity of the derived collapse load that was based on plastic analysis. Major findings obtained from tests are summarized as follows: (1) the test specimens of exterior diaphragm type moment connection exhibited sufficient deformation capasity until 0.1 rad drift angle, (2) the derived collapse load formula correlated well with the specimen which were connected beam flanges to diaphragms by weld.
