A MINIMALLY INVASIVE MOTILITY VISUALIZING SYSTEM

Not Available Presidential Executive Order 12941 requires that all federal agencies inventory their buildings and estimate the cost of achieving adequate seismic safety. The Foster-Miller team provides an innovative seismic retrofit solution, noted expertise in event modeling and code revision and a clear path to cost-effective production. The resultant energy dissipation product will provide a viable alternative to the use of viscous dampers at a fraction of the cost. The proposed concept builds on a novel idea put forth for the Osaka convention center in Japan. Yielding diagonal frame members can be included in a new building, or added as a retrofit, to provide energy dissipation during a seismic event. Foster-Miller will develop a diagonal bracing system that will yield in both tension and compression to achieve energy dissipation. Hybrid carbon and fiberglass pultruded composite braces will be used to constrain buckling under compression loads while not adversely contributing to the axial stiffness. Foster-Miller will direct the program and provide expertise in design, modeling and implementation of novel composite structures. Fluor Daniel will support the assessment of performance and code requirements. McNamara/Salvia will provide seismic evaluation and design expertise. Glasforms, a leading pultrusion manufacturer, provides cost-effective commercial production. BENEFITS: The proposed system is a low cost option for seismic energy dissipation in both new and retrofitted buil
