Title: Earthquake-Resisting Shearwalls - New Zealand DesignTrends
Author(s): Thomas Paulay
Publication: Journal Proceedings
Appears on pages(s): 144-152
Keywords: deformation; diagonal tension; ductility; earthquake resistant structures; earthquakes; failure mechanisms; reinforced concrete; shear properties; shearwalls; structural analysis; structural design.
Abstract:Design considerations for earthquake-resisting shearwalls with a particular emphasis on desirable energy dissipation properties are reviewed. After a brief description of different structural responses to seismic motions and the derivation of ensuing actions, criteria for the intended ductile flexural behavior of shearwalls are examined. In somewhat greater detail failure modes in shear and the means of controlling excessive seismic shear deformations, considered to be particularly detrimental to stability in stiffness and energy dissipation, are discussed. Detailing requirements for the reinforcement of coupling beams and the boundary zones of ductile shearwalls, considered in New Zealand to be desirable, are reported.
