BS ISO 19338:2014 pdf free.Performance and assessment requirements for design standards on structural concrete
The overall quality of a structure shall be implemented through strict quality control and care by a knowledgeable qualified design professional complying with ISO 2394, ISO 6241, and ISO 7162. In conceiving a structural system, load-carrying behaviour under maximum and frequent loads, materials and their combinations, constructibility, costs, and environmental aspects and aesthetics shall be considered.
Design of concrete structures shall provide general structural integrity, directly or implicitly. Localized damage or deterioration in a structure shall not impair general structural integrity.
A design standard for structural concrete shall be based on quantitative performance evaluation at the limit states. Design shall consider safety, serviceability, restorability, structural integrity, robustness, environmental adequacy, and durability. Where applicable, limit states caused by fatigue, fire, explosion, impact, and rare accidental actions or other extreme loadings or actions shall be considered.
Design service life shall be defined in consideration of the structural role, the social importance of the structures concerned, and the economically justified service life. Structural requirements shall be satisfied throughout the defined design life.
In order for the properties of the completed structure to be consistent with the requirements and the assumptions made during the planning and design, quality assurance and execution expectations for construction shall be considered and adequate quality control measures shall be taken.
For limit states, the design standard shall specify sets of action combinations and a reliability-based design concept that can be analytically demonstrated to give an adequate performance level during the design life of the structure.
Dynamic response and/or periods of vibration of a structure shall be considered and limited to avoid discomfort to occupants, impairing use of the structure, and/or avoid the risk of resonance. Dynamic analyses shall be used where required.
Damages in structures caused by loadings and actions, such as earthquake forces and environmental actions, shall be limited so that the maintenance and repair works could be conducted by an economically and technically feasible way. Restorability shall be considered using factored loads and action combinations in which the load factors correspond to an acceptable probability of occurrence of the restorability limit state being checked.
The structure shall be designed such that deterioration does not cause it to reach an ultimate limit state, a serviceability limit state, a restorability limit state, or a fatigue limit state during its design life. Regular maintenance shall be prescribed (in the standard or through reference to an international, national, or regional standard) and considered in determining the design service life of a structure.BS ISO 19338 pdf download.
