Application of High-Strength Concrete in Seismic Regions

Possible applications of the use of high strength concrete in structures designed to respond to the strong ground shaking of earthquakes is discussed. The basis of the building code requirements is discussed and various limitations are explored. The need for detailing of members to ensure ductility is discussed and how the high stresses that can be present in high strength concrete members will require more stringent confinement reinforcement as well as other detailing procedures. The paper urges caution when designing with high strength concrete in seismic regions.
