Design Concepts and Applications of High-Strength Concrete in New Zealand

Abstract

An overview is presented on New Zealand applications and design concepts for the utilization of high strength concrete (concrete compressive strength greater than 55 MPa (8,000 psi)) in various forms of structures that are required to withstand seismic loading. In order to take advantage of the high concrete compressive strengths and enhanced durability designers and researchers are investigating various structural applications. The performance of elements of these structures ranges from remaining elastic during a major seismic event through to being required to exhibit significant ductility in the major events.
