SIA 263:2013 — Steel structures
SIA 263 is the Swiss standard for the design of load-bearing steel structures, published by the Swiss Society of Engineers and Architects (SIA). It covers materials, the classification of cross-sections, the resistance of members and connections, stability, fatigue and serviceability. It is used together with SIA 260 (basis of structural design) and SIA 261 (actions on structures). The current edition is SIA 263:2013.
