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.
