Abstract
![CDATA[The last forty years of Australian seismic activity history has consisted of two major earthquake events. The 1978 Meckering Earthquake in Western Australia was the first major earthquake attributed with triggering the publication of AS-2121 [1] in 1979. The 1989 Newcastle Earthquake is attributed with the development of AS-1170.4 [2] in 1993; this standard was a significant improvement in comparison to the 1979 AS-2121 [1] publication. The most recent Australian Standard which focuses on the design of buildings with respect to earthquake loads is AS-1170.4 [2] published in 2007, which includes amendments that have been made as recent as March 2018. Additionally, Australia has developed standards which complement AS-1170.4 [2], these include; AS-3826 – Strengthening existing buildings for earthquake [3], AS/NZS-4671 - Steel reinforcing materials [4], AS/NZS-1554.3 Welding of reinforcing steel [5]. AS-3826 [3] focuses on improving the seismic resistance of existing buildings by ensuring the load capacity of both existing and/or additional strengthening components effectively satisfies the load combinations given in AS-1170.1 [6] and AS-1170.4 [2] respectively. Whereas, AS/NZS-4671 [4] outlines specific requirements for providing steel reinforcement with ductility appropriate to earthquake prone concrete structures (i.e. Class-E). Furthermore, the development of AS/NZS-1554.3 [5] has further aided seismic design in Australia by outlining which welds are unsuitable for seismic resistant applications. This paper will present both previous and current research related to Australian Seismic Design (ASD). ASD research consists of crucial topics such as; improvement of building drift performance, study of building collapse mechanisms and changes to reinforcement design which reduce earthquake stresses within structural elements. Overall, this review paper will outline specific changes and improvements/developments made to Australian Standards which govern seismic activity design from 1979 until present time.]]
