Analysis of cracking in RC tensile members using beam finite elements with embedded transversal cracking

In this paper we present our recent work on modelling cracking mechanism in reinforced concrete members subjected to uniaxial tension. A novel embedded-crack beam/bar finite element is proposed, in which crack formation and development, as well as the stress transfer between the reinforcement bars and surrounding concrete matrix are implemented, and tested for monotonically increasing loading. The proposed approach is capable of determining both the position and width of an opening crack. Particular emphasis is given to the numerical problems related to the arc-length solution procedure used to track the complete load displacement response of the member.
