Earthquakes can badly damage concrete buildings, and better materials could make them safer. High-performance fiber-reinforced cementitious composites (HPFRCCs) are concretes mixed with fibers that make them highly ductile, able to bend and stretch without breaking apart.

What they work on
- Quantify plastic hinge response, how bending zones absorb energy, of HPFRCC components under combined axial load and bending through physical experiments and detailed computer simulations.
- Create computationally efficient models that capture the response and failure of highly ductile concrete components for system-level seismic analysis of buildings.
- Develop seismic design criteria and perform risk assessment and cost-benefit analysis for reinforced concrete building systems that use HPFRCCs.
More about the research
They also resist cracking. Earlier studies showed they greatly improve how individual building parts respond to earthquakes. This CAREER project asks how HPFRCCs perform across whole building systems, and how engineers should design with them.
Why it matters
Design methods for buildings that use highly ductile fiber-reinforced concrete could help engineers build structures that hold up better in earthquakes. This could improve life safety for occupants. Cost-benefit and risk analyses could show communities and designers when these materials are worth their cost over a building's life.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
