LOAD-BEARING CAPACITY, BOND BEHAVIOR, ENVIRONMENTAL IMPACT AND APPLICATION OF BFRP-REINFORCEMENT IN CONCRETE

Abstract

Because of its high tensile strength, high durability and comparatively low environmental impact reinforcement made of BFRP should be investigated on its usability as structural reinforcement. Further, there is the ability to increase the life span of concrete members due to the use of BFRP-reinforcement, what can also lower the environmental impact. Due to the fact that reinforcement products made of BFRP are not generally regulated normatively in Germany, there are many characteristics that have to be investigated experimentally At the Kiel UAS experimental and numerical investigations on the flexural and shear capacity and the bond and cracking behavior of BFRP-reinforced concrete members were carried out. Based on this, specific applications where developed. As examples a BFRP-reinforced bridge cap made of RC-concrete and a ground plate with BFRP-reinforcement can be named. In conclusion we can say that the benefit of using BFRP-reinforcement depends on the application. Especially in corrosive milieu BFRP-reinforcement can be a useful alternative to steel-reinforcement.
