The applicability of extended stiffened end plate (ESEP) connections used as link‐to‐column connections in eccentrically braced frames (EBFs) with long (flexural yielding) links is examined in this paper. A finite element method (FEM) is used for this purpose, based on a validated parametric FE benchmark. Analysing the numerical model of an ESEP connection designed to the recent seismic design rules for special moment frames reveals that the link‐to‐column connections of EBFs sustain more severe conditions than the moment connections of moment‐resisting systems. The design approach implemented is examined and the results are discussed. The results demonstrate that ESEP connections can be used as a successful alternative for the link‐to‐column connections of EBFs and the system with this type of connection can achieve the required rotations for long or flexural links.
