Generally, the prefabricated steel-framed buildings use beam-column frame system. The system which uses concrete filled square tubular columns exhibits a good structural behavior especially under lateral loading condition. Experimental studies were performed to develop proper details of concrete filled square tubular column to wide flange beam connections. Consequently, a beam-column connection sub-system are proposed for application to an prefabricated steel-framed building package. Principal results obtained from this study are as follows: 1) the frame system using concrete filled square tubular columns, compared to other frame systems, has some advantages such as reduction of steel-frame weight, space flexibility, etc. 2) one type of semi-rigid connection and two types of rigid connection are finally proposed for the connection sub-system considering connection stiffness and workability.
