High-strength reinforcement in concrete members subjected to bending

摘要

High strength reinforcement has been used in geotechnical applications and for structural applications in columns and shear walls for more than 10 years. A recent research program dealt with the application for flexural members. The main topics were the bond behavior and the crack width prediction of S 670 as compared to common reinforcement B 500 B and higher strength reinforcement S 600 which has a similar relative rib area as S 670.
