NBR17196 DE 03/2025

Esta Norma estabelece os requisitos e os critérios para o projeto de estruturas de concreto armado com barras de polímero reforçado com fibras (FRP). Esta Norma aplica-se a concretos estruturais sem ou com uso de fibras discretas pertencentes ao grupo I de resistência (C20 a C50), conforme as NBR8953 ou NBR16935. Esta Norma considera as barras de polímero reforçado com fibras (FRP) fabricadas a partir de polímeros termofixos e fibras contínuas de vidro ou basalto, por meio de processo industrial, e que estejam conforme a NBR17201. This Standard establishes the requirements for the design of concrete structures reinforced with fiber-reinforced polymer (FRP) bars.This Standard applies to structural concretes without or with the use of discrete fibers belonging to resistance group I (C20 to C50), in accordance with NBR8953 or NBR16935.This Standard considers fiber-reinforced polymer (FRP) bars manufactured from thermosetting polymers and continuous fibers of glass or basalt, through an industrial process, and that meet the requirements of NBR17201.
