Simulation of Tension Behavior of Reinforced Concrete Members Strengthened with CFS by Using RBSM (original) (raw)

Abstract

This paper presents numerical simulation to the tension behaviour of reinforced concrete (RC) members strengthened with externally bonded Carbon Fiber Sheets (CFS) by using two dimensional Rigid Body Spring Model (RBSM) ([1] and [2]). A non-linear reinforced concrete model strengthened by CFS, with bond-slip models and bond deterioration models to simulate both the steel reinforcement bar-concrete interface and the CFS-concrete interface were applied in the RBSM numerical code. It is reported that the RBSM analysis can represent the experimentally observed phenomena very well.
