FULL SCALE TEST ON THE TRANSITION FROM DUCTILE FRACTURE TO BRITILE FRACTURE OF BEAM-TO-COLUMN CONNECTIONS WITH ORDINARY TYPE WELD ACCESS HOLES

In the beam-to-column connections, there is a possibility that the plastic deformation capacity decreases by brittle fracture. Full scale test on beam-to-column connections with ordinary type weld access holes was carried out. Major test parameter was temperature. The plastic deformation capacity and the load-carrying in the transition area were evaluated from the test result, and were compared with previous experimental results. Deformation capacity is largely influenced by the mechanical property of the material. The material used in the test was special one and had unique properties. Then, the material properties were replaced and corrected by the ordinary one in analyzing the deformation capacity.
