Seismic design provisions for fastenings to concrete in Australia

Design for seismic actions is increasingly becoming a consideration for engineering projects in Australia due to the requirements of AS 1170.4. Important infrastructure and buildings providing essential services such as hospitals must continue to function following a seismic event. For this reason it is imperative fastenings to concrete are suitably prequalified and designed for seismic loads in such structures. The scope of the design provisions for fastenings to concrete in Australia that are provided in Standards Australia TS 101:2015 do not cover design verification for seismic loading. This paper provides a summary of the European and US seismic prequalification and design requirements being considered for adaptation to suit Australian requirements, including how these are relevant to the importance levels stipulated in the National Construction Code.
