Analysis-based design provisions for steel storage racks
The paper summarises the main new design provisions included in the recent draft Australian Standard for Steel Storage Racks. The Standard features multi-tiered analysis provisions ranging from basic linear-elastic analysis-based provisions to highly advanced integrated design-analysis (GMNIA) provisions which allow the analysis and design to be completed in one step. The GMNIA provisions distinguish between beam-element-based and shell-element-based analysis according to the cross-section slenderness, and provides rules for the imperfections to use for the two types of analysis, including imperfections in the local and distortional buckling modes for the shell-element-based analysis. The selection of the system-based reliability (resistance) factor (fs) is discussed. The Standard is seen as the most advanced design code of its type presently available for frame-type steel structures.
