Abstract
During Great Hanshin-Awazi Earthquake, brittle fracture was caused at beam-to-column connection of P75 steel pier. In this study, concerning the brittle fracture at P75 pier, simulations of brittle fracture at beam-to column connection is carried out by using large scale specimens simulating the P75 beam-to-column joint. In addition, as improve or retrofit details of beam-to column connection against such brittle fracture, some improved specimens which include ribs at corners of connection are also used. As a result, there is a high possibility that brittle fracture is caused at corner of connection where there is a high strain concentration. On the other hand, improve or retrofit details studied in this study are much effective.
