Abstract

Recently, simulation of bending failure of RC members was successfully done where concrete was modelled by a classical plasticity model with 8 nodded cubic element and the reinforcement was modelled as 2 nodded rod element. Though the analysis was successful, umealistic confinement effect was noticed near the stirrup in the compression zone. In this paper, a simplified beam element is proposed for modelling of reinforcement in compression region. Sectional properties are calculated at gauss points and integration is done to calculate the stiffness matrix. Though the results looks promising, the model is still in the developing stage.
