This $200,000 National Science Foundation Project Grant under the Engineering (47.041) program will support Marquette University's development of segmented braces for improved seismic performance and repair of concentrically braced frames. The university will conduct experimental testing and computational modeling to evaluate the seismic behavior and residual capacity of segmented brace designs that focus repair on the brace midspan. This aims to facilitate relatively fast, low-cost replacement of damaged brace segments while retaining other frame components. The research activities will inform design and modeling guidelines for segmented braces suitable for engineering practice to enhance seismic resiliency and post-earthquake recovery of braced frame buildings. Completion is scheduled for July 2024.
