摘要
This paper presents a finite element modelling of a new geosynthetic cementitious composite material called GCCM. The framework adopted a concept of concrete externally bonded by fibre-reinforced polymer (FRP). The existing bond-slip model was used to predict a flexural behaviour of GCCM, considering the effect of needle punch process during manufacturing. The finite element modelling was calibrated against the experimental data of bending tests. The parameter optimisation was employed to define a set of the bond-slip model parameters. The analytical load-displacement curves predicted by the bond-slip model could agree well with those obtained from the experiments.
