Investigation and determine of impact toughness of groove welds and comparing with seismic provisions of weld connections

Preventing brittle fracture in the connection welds of the steel members is one of the most important issues in the performance of steel structures. Bitter experiences of Northridge earthquake in the case of “demand critical” welds such as complete-joint-penetration (CJP) groove welds in the connect...
