CFRP-bar NSM system이 적용된 RC부재의 부착거동에 관한 해석적 연구

In the CFRP strengthening system, NSM system is paid attention to many researchers all over the world due to many advantages such as strengthening efficiency with respect to externally bonded reinforcement. This study focuses on the analysis about the bond behavior of NSM system for the existing R.C substrate members. Nonlinear finite element analysis has conducted with MIDAS-FEA, overviewed with the results of pull-out test. This paper provides a basic concept for variables effected on the bond strength about the CFRP-bar to concrete joint with NSM system.
