STUDY ON FRACTURE TOUGHNESS AND CRITICAL CRACK LENGTH OF EXISTING STEEL HIGHWAY BRIDGE MEMBERS

In this study, fracture toughness of existing steel highway bridge members was investigated by CTOD and Charpy Impact tests, and critical crack length, at which fatigue crack shifts to the brittle fracture, was discussed. Critical CTOD value, δc became 0.058mm(-30℃) and 0.027mm(-50℃) based on the lo...
