000012091 520__ $$2eng$$aLarge-scale experimental studies of buckling-restrained braced frames (BRBFs) have shown that although they display good overall performance, they may have limitations due to connection failure modes that do not allow the braces to realize their full ductility capacity. These experimental results motivate further investigation of BRBF connection behavior and performance. In this study, nonlinear finite element models are used to study BRBF connections with emphasis placed on the beam-column-brace connection regions. The models focus on a one-story subassembly that is part of a four-story BRBF, which was tested previously. After the baseline finite element analysis results are verified with experimental data, parametric studies are conducted to explore variations in connection configuration. Results are discussed on global and local levels. The effects of the parametric connection variations are assessed and key issues that influence performance are identified.
