Analysis of 1-D Tension Stiffening with Discrete Cracks
The paper describes the development of a new one dimensional (1-D) model to simulate tension stiffening of cracked concrete. The model formulates the analytical relationships through stiffness of the concrete-rebar composite and assembles a set of finite elements. One of the advantages of the element's formulation identified was that its stiffness matrix is exact in that it is derived from the governing differential equations of the composite element. Using the formulation provides a complete 1-D distribution of stresses, strains and displacements along the rebar as well as the bond stress and slip variation along the common interface. The paper presents numerical examples to demonstrate the model capabilities and its predictions.
