Charpy impact test has been established as a convenient evaluation method for the toughness of steel materials. Since the Hyogo-ken Nanbu earthquake, even in the field of building structures, technical standards to prevent the brittle fracture of steel members have been introduced and the required value of the Charpy energy absorption has been standardized. However, the result of Charpy impact tests differ widely depending on the material properties. Therefore, it becomes important to clarify the correspondence between the difference of the result of Charpy tests and the ductility of real structures. In this investigation, using two materials which have different properties in terms of Charpy test, the full scale test on the structural behavior was carried out. Under the controlled temperature, the difference of the full scale test was minutely examined by comparing the difference of the Charpy energy transition curve of materials.
