Driven by an overall vision to develop an innovative building system that sustains minimal structural damage during a large earthquake (e.g., the Design Basis Earthquake), this research project at the University of Notre Dame involves the investigation of self-centering, energy-dissipating “hybrid” precast concrete wall structures for use in seismic regions. Buildings with this system are expected to be economical not only to construct but also over their service life because they remain operational after a large earthquake.

The most pressing market need related to the three-year project funded by the Charles Pankow Foundation and the Precast/Prestressed Concrete Institute is code approval of the new hybrid system based on ACI ITG T5.1 and ACI ITG T5.2. Achieving this task would provide a major advancement for the building construction industry, with broad applicability in moderate and high seismic regions.

The required experimental validation and associated design and analytical studies for hybrid precast wall structures will be conducted during the course of the project. The key deliverable will be a Design Procedure Document for use by practicing engineers, precast producers, owners, and regulators in seismic regions.
