ISO 14484:2020 pdf free.Performance guidelines for design of concrete structures using fibre-reinforced polymer (FRP) materials
This document provides general principles for the verification and assessment of the performance of concrete structures with the applications of different fibre-reinforced polymer (FRP) systems varying from internal FRP reinforcements/tendons, external FRP tendons, externally bonded FRP sheets/plates, to near-surface mounted FRP reinforcement. It can be used for the international harmonization of the design of un-reinforced, conventionally reinforced, and pre-stressed concrete structures with the use of the above-mentioned FRP systems.
Concrete structures with FRP materials include concrete structures with the sole use of FRP materials and those with the combined use of FRP materials and steel reinforcement.
Design of concrete structures with FRP materials should consider safety, serviceability, and restorability during service life. Where applicable, limit states caused by fire, seismic actions, or other extreme loading or actions (e.g. impact and fatigue) should also be appropriately considered, according to the intended applications of FRP materials (i.e. as the strengthening layer or the internal reinforcement). In addition to the above, costs should also be taken into consideration.
Suitable analysis should be performed to verify that the performance requirements for concrete structures with FRP materials in terms of limit states such as serviceability limit states (SLS) and ultimate limit states (ULS) in accordance with ISO 2394 are satisfied.
In the case of upgrading existing concrete structures with FRP materials, the strengths of concrete and steel should be determined with consideration of the in situ conditions, such as measured material and geometric properties of the existing concrete structures, instead of their material strength values used in the original design.
Structural analysis of concrete structures with FRP materials should consist of the determination of structural response for the examination of limit states such as ultimate limit states and serviceability limit states. In general, structural analysis methodologies specified in ISO 19338 for structural concrete with traditional reinforcing materials may be applied for concrete structures with FRP materials.ISO 14484 pdf free download.
