| Research Abstract |
Exterior diaphragm type connection, which does not require fullpenetration weld, is a rational method of connection between beams and columns in terms of high reliability for its seismic performance. All of the previous studies on the connection targeted one direction loading, and the design method has been established. On the other hand, there could be the case that structural designers are required to assume the connections to be input from two directions. In this study, a systematic cyclic loading test was mainly conducted, and structural performances of the beam-to-column connection stiffened by exterior diaphragms were investigated in order to confirm the design method of the connection under bi-axial loading.
