Abstract:
Historically, development of new materials has preceded the development of design criteria. High-strength concrete (HSC) has not been exempt from this trend. One of the striking mechanical characteristics of HSC has been its relative brittleness when compared to normal strength concrete (NSC). This paper summarizes the important findings from more than 5 years of study conducted at the University of Nebraska-Lincoln on two design issues covering ductility of HSC columns and bond of reinforcing bars to HSC. The term HSC used in this paper implies concrete with compressive strength exceeding 10,000 psi.
