Abstract:Nonlinear fibre beam models, due to its intrinsic simplicity and computational efficiency, are often an adequate alternative to the complex nonlinear plane and solid FE models for the assessment of entire frame structures. Nevertheless, simulations of structural concrete members undergoing relevant shear stresses cannot be performed by these models, as nonlinear shear effects and shear-bending interaction are neglected. In turn, the presence of shear stresses in cracked reinforced concrete (RC) elements leads … Show more
