A Perspective on the Seismic Design of Precast Concrete Structures in New Zealand

Abstract

The author describes trends and developments in the use of precast concrete in New Zealand for floors, moment resisting frames, and structural walls of buildings. Currently, almost all floors, most moment resisting frames, and many one- to three-story walls in buildings are constructed incorporating precast concrete elements. Aspects of design and construction, particularly the means of forming connections between precast concrete elements, are discussed. The paper emphasizes seismic design; the aim of the design methods for frames is to emulate monolithic construction. Examples of recent precast concrete buildings using the above discussed methods are presented
