A coupling model of reinforced concrete fracture

In this paper, a coupling model is presented for analysis of reinforced concrete fracture. An effective approach, the Boundary Collocation Method, and an iteration procedure are employed in the analysis. Based on the assumed suitable stress functions, stress intensity factors, displacements of the crack surfaces and forces of the steel reinforcement can be easily calculated. Further analyses, such as determination of the ultimate load and direction of the crack propagation, can also be carried out on the basis of the present calculation and fracture criteria.
