Prediction of brittle fracture initiating at defects in the end of complete joint penetration groove welds

摘要

This paper concerns the applicability of two approaches for predictionof brittle fracture in the beam-to-column connection. One is a methodusing Weibull stress approach, the other is a method based ontoughness scaling model (TSM). The experiments using beam-tocolumnjoint models, which were designed to represent beam-tocolumnconnections with through diaphragm, were tested. Predictionsusing the Weibull stress approach and the toughness scaling modelwere performed and compared with the test results.
