The introduction of AS1170.4 2007 in Australia has outlined specific seismic design and performance criteria for building structures and their structural response. Further, combined with the release of AS3600 2018, specifically section 14 design for earthquake actions, the seismic design and analysis of reinforced concrete structures has become more onerous for ductile response. The increased detailing requirements for ductile sway frame structures in particular results in more costly structures both in terms of section size and reinforcement quantity. This has compounding effects for space and cost viability for commonly built commercial structures in Australia such as retail spaces and carparking structures. From a professional engineering office perspective, the increased detailing associated with a higher ductility class is not cost effective or practical, and the choice of analysis method is based entirely on reducing cost whilst meeting performance criteria. For retail structures that don’t contain shear core or wall structures, moment resisting frames (MRF’s) are the only lateral bracing against seismic loads. Typically, these MRF’s in Australia are constructed with small columns, one way band beams, and one-way slabs which are post-tensioned for deflection control. Any stair or lift cores are often limited in number or isolated in positions across the floor plate that provide little overall structural bracing. Therefore, more sophisticated methods of analysis are necessary to achieve a viable and practical design for these structures in the low seismic risk region of Australia. This paper presents the use of non-linear push over analysis with the Capacity Spectrum Method for one-way band beam and slab sway frame structures built throughout the state of Queensland. The method may be used to demonstrate that standard detailing to the main body of AS3600 achieves a minimum ductility of 2 (limited ductility) without the need for higher ductility class detailing to section 14 to satisfy seismic demand. A mixed-use retail building is presented with transfer beams and is analysed using a 2D and 3D frame pushover analysis.
