Title: International Hybrid Simulation of Tomorrow's Braced Frame Systems (NEES-2008-0605)
Year Of Curation: 2012
Description: Braced frame systems offer an attractive solution to the multiple design criteria within performance-based seismic engineering. Their elastic properties provide the stiffness and strength needed to achieve operational performance objectives which are primarily associated with non-structural performance. If detailed properly, their ductility and energy dissipation capacities can meet even severe demands resulting from extreme events. However, previous research results have indicated that current design methods prevent braced frames with buckling and buckling restrained braces from achieving this. International practicing and research engineers recognize this issue. A recent meeting looking towards engineering steel buildings for the next decade agreed that the development of reliable braced frame systems was a top priority in seismic steel research and to achieve this, a coordinated effort was essential, that PBEE should provide the framework tying the activities together, and that the research community should partner strategically with international research organizations and work collaboratively with industry, professional practice and organizations.
