- Abstract
- This paper develops a reinforced concrete model that is based on the novel hybrid finite element-scaled boundary finite element method for fully automatic multiple cohesive crack propagation in reinforced concrete beams. The hybrid method can efficiently extract accurate stress intensity factors from semi-analytical solutions of stresses or displacements and is also flexible in remeshing multiple cracks. The RC model lumps adjacent reinforcements into a layer of four-noded quadrilateral elements that is connected to the concrete bulk with cohesive interface elements. These elements model the concrete-steel interaction and consider both bond-slip and splitting tensile crack mechanisms. A reinforced concrete beam is modelled. The numerical results show good agreement with both experimental and numerical results available in literature. © Civil-Comp Press, 2010.; Civil-Comp Proceedings
