Emerging wireless sensor technology presents a tremendous opportunity for developing low-cost monitoring systems for civil infrastructure. A set of wireless MICA2 mote accelerometers were deployed on a reinforced concrete bridge column to collect data during a shaking table earthquake simulation test. The data from the test were ingested into a data and(More)
To explore the feasibility of improving the delivery process of reinforced concrete, we focus in this paper on reinforcing bars (rebar) used in cast-in-place (CIP) concrete. Specifically, we describe the methodology for set-based design of rebar that we are pursuing in an ongoing research effort. Set-based design makes it possible to maintain feasible(More)
Post-earthquake repair costs are important for evaluating the performance of new bridge design options and different existing bridge configurations in the next major earthquake. Hazard and structural demand models provide information on the probabilistic structural response during earthquakes. Damage and decision models are needed to link the structural(More)
Two discrete-event simulations are developed to assess the feasibility of improving the delivery process of reinforced concrete structures. The simulations represent the resource and information flows necessary for supporting set-based design of reinforcing bars used in concrete. Set-based design enables the exploration of feasible solutions for longer in(More)
