Here we have compiled all of our papers to date on a U.S. National Science Foundation funded research project focused on advancing reliability-based analysis and design of structural systems. Current structural design codes are almost exclusively calibrated to consider only component reliability (failure probabilities), needlessly constraining designers in considering the performance of the system—as a whole—when making designs. The principal goal of this research is to provide a rigorous path to transformation of structural design from a component-based process to a system- based process. The system reliability design methodology is generally posed and demonstrated with cold-formed steel framing, a repetitive construction technique with multiple load paths and beneficial ‘system effects’. The research team is made up of professors and students from Virginia Tech, Johns Hopkins University, University of Massachusetts, and the American Iron and Steel Institute.
