| 要旨 | This paper presents 2D simulation of concrete cover separation, a popular premature failure mode of FRP strengthened RC beams, by using Rigid Body Spring Model (RBSM). To simulate this complex failure mechanism, special consideration of the interfacial behavior is taken into account by applying constitutive laws for radial stress caused by tension steel and shear bond stress at the interface between steel/concrete as well as FRP/concrete. The reliability of the approach is then validated by comparing results from the analysis with those of experiments collected from other researches. |
