SIA 262:2025 — Concrete structures
SIA 262 is the Swiss standard for the design of load-bearing concrete structures, published by the Swiss Society of Engineers and Architects (SIA). It covers reinforced and prestressed concrete: materials, the resistance of members and sections in bending, axial force, shear, torsion and punching, serviceability and detailing. It is used together with SIA 260 (basis of structural design) and SIA 261 (actions on structures). The current edition is SIA 262:2025, in force since 1 November 2025, which replaces the 2013 edition.
