CRACK PROPAGATION OF REINFORCED CONCRETE MEMBERS AND MODELLING OF CONCRETE BY THE FINITE ELEMENT METHOD

The finite element method is applied to the study of crack propagation in reinforced concrete beams. Cracking is simulated in the finite element model by introducing "local anisotropy" in areas where cracks tend to form. Good agreement between analytical and experimental results is obtained in shapes and distribution of cracks and in the ultimate strength of the structure. The method is also applied to a study of the mechanical behavior of the concrete model. Elastic modulus of concrete obtained from the model agreed reasonably well with test results. The effect of friction on the loaded faces was simulated by means of spring elements. It was found that the stress distribution and mode of failure in the finite element model were in accord with common experience: end friction had a significant effect. /Author/
