| Outline of Final Research Achievements |
Exterior diaphragm type connection, which does not require complete joint penetration weld, is a rational method of connection between beams and columns in terms of high reliability for its seismic performance. The objective of this study is to rationalize the design method of exterior diaphragm type connection for concrete filled steel tubular structures. For the rationalization, details of connections, in which the beams on either side of the columns have a different depth, and existence of concrete slabs are important factors which should be considered in the practical design. In this study, a systematic cyclic loading test including two factors of the above was conducted, and the estimation methods of structural performances of the connections were investigated.
