Extended stiffened end‐plate bolted joints are widely used in seismic resistant steel frames. In the United States of America (USA) this type of joint is seismically pre‐qualified according to AISC 358. In Europe prequalification criteria are under development within the framework of the ongoing EQUALJOINT research project. Even though the design rules of both approaches are based on the principles of hierarchy of resistances, there are some differences. In order to clarify these aspects, this paper describes both design criteria and rules. In addition, the results of a large parametric finite element investigation are used for discussion.
