Abstract:
Concrete materials with high ductility and strength have emerged in recent years with applications to improve the seismic response of reinforced concrete structures. This presentation will explore differences in component-level response between traditional reinforced concrete elements and those made with highly ductile systems through recent experimental testing and numerical simulations. The plastic hinge response, rotational capacity, and failure modes in elements with highly ductile concrete materials will be presented, and implications for design of components using these materials will be discussed. The system-level seismic response of building frames incorporating these emerging materials will then be presented and implications in terms of construction (concrete volume, rebar tonnage, etc.) and structural response (collapse capacity, mean annual frequency of collapse, etc.) will be discussed.
