Welcome to the online home of the Fahnestock Research Group within CEE at Illinois. Led by Prof. Larry Fahnestock, and collaborating with colleagues at Illinois and other universities, the group conducts research broadly related to behavior, design and performance of large-scale structural systems. We employ laboratory and field testing in conjunction with analytical and numerical models to illuminate critical aspects of behavior that inform advances in system configurations and design methods, ultimately leading to superior performance that contributes to infrastructure resiliency and sustainability. Research topics span across buildings and bridges, moderate and high seismic design, low and high ductility response, service and extreme load conditions. Current projects are sponsored by the National Science Foundation, American Institute of Steel Construction, Illinois Center for Transportation and Illinois Tollway. This site provides a brief overview of the group activities, so please inquire for more details about anything posted here.
