The Engineering Research Center for Advanced Technology for Large Structural Systems at Lehigh University conducts integrated research and education programs in design, fabrication, construction, and in-service monitoring of structures. Major efforts are focused on design of connections for automated construction, creation of knowledge-based systems for computer integration of construction processes, applicability and efficacy of novel structural materials for initial construction and for structural rehabilitation, and sensing and instrumentation for in-service monitoring of structure condition and performance. A large multi-wall loading facility has been completed and is available for research experimentation. This action is a five year renewal.
