Seismic eccentrically braced frames

Abstract

Abstract This paper provides an overview of the behavior and design of seismic‐resistant eccentrically braced frames (EBFs). Basic characteristics of EBFs are first discussed. The important effects of link length on the performance of EBFs are reviewed. The capacity design concept for EGFs is then addressed. The paper addresses several design issues that appear to have been inadequately considered either in current practice or in the emerging seismic code provisions. Some important observations are provided from pseudodynamic tests of large EBFs and experimental studies of EBF subassemblages with link‐to‐box column connections conducted recently. Future research needs are discussed.
