Abstract Details

2017, Master of Science, University of Akron, Civil Engineering.
The friction-damped braced frame system with buckling restrained columns (FDBF-BRC) is being developed to provide significant drift capacity while limiting damage due to residual drift and soft-story mechanisms. BRCs will be on both ends of the frame, where they will experience tension and compression due to conditioned earthquake simulations on OPENSEES. This research is a continuation of previous work by Dr. David A. Roke’s previous graduate student, Dr. Felix C. Blebo, for multiple stories, based on the established design recommendations. This study includes buildings with 4, 6, and 8 stories, with application of recommended frame hardening factor and BRC hardening factor. This system consists of beams, columns, braces interlocking at a central column, a pinned support condition, and BRCs at both external columns of first story. Energy dissipation to minimize overall seismic response on each floor level are products of the incorporated BRCs and friction generated at the lateral-load bearings. A suite of 20 DBE, 20 MCE, and 20 FOE-level ground motions is numerically applied to several FDBF-BRCs. Based on dynamic analysis results, the FDBF-BRC still proves to be an effective seismic-resistant system. The system’s performance shows a nearly uniform inter-story drift response, high ductility, and high energy dissipation capacity.
