Civil Engineering Association

(1) This standard covers the design and construction of structures (including civil engineering structures) made from plain, reinforced and prestressed concrete with normal-weight and lightweight aggregate, of strength classes C12/15 to C100/115 and LC12/13 to LC60/66. The specifications of this standard apply to both normal-weight and lightweight concrete of the same strength unless expressly stated that a specification covers lightweight concrete only.
(2) This standard also applies to the design and construction of unreinforced walls in dwellings made from lightweight concrete of strength class LC8/9. The concrete parameters required for their design shall then be derived from the provisions given in subclause 9.1.
(3) This standard specifies requirements relating to the loadbearing capacity, serviceability and durability of structures. The serviceability analysis ensures the fitness-for-use, and to some extent the durability, of a structure. Theoretical limiting values relating to the durability of a structure are binding, the theoretical limiting values relating to its serviceability are given as guidance values.
(4) This standard does not cover the following:
a) members made of no-fines lightweight concrete, aerated concrete, heavyweight concrete and members containing reinforcement with a loadbearing function;
b) special types of construction (e.g. mining shafts);
c) thermal and sound insulation, and structural fire protection.
(5) For the design of certain civil engineering works made of concrete (e.g. bridges, segmental structures, dams, pressure vessels, offshore platforms, tanks), additional requirements may need to be taken into consideration.
(6) Additional requirements and analyses are required in the design and construction of structures in earthquake zones (e.g. paying particular attention to the ductility of members and reinforcement).
(7) This standard does not contain provisions relating to the analysis of loadbearing capacity of lifting appliances, for which reference is made to Merkblatt ZH 1/17 Sicherheitsregeln für Transportanker und -systeme von
