چکیده مقاله
Eccentrically braced frames EBFs are expected to withstand significant inelastic deformations in the links when subjected to the forces resulting from the motions of earthquake In this study, behavior of various examples of link to column connections is investigated using finite element analysis Parameters which are considered in the finite element models for investigation include connection details, length of links, welding modeling, various weld access holes, and loading protocol constitute of revised and old cyclic loading protocol given in the 2005 and 2002 AISC seismic Provisions, respectively In order to show the validity of the analysis, results are compared with those obtained experimentally in the laboratory in America by Okazaki et al in 2009 Finally, the results show that most of the connections are susceptible to failure at link flange near the weld before to achieve required plastic rotation capacity acknowledged in AISC 2005 Provision
