Research abstract
AN ANALYTICAL MODEL FOR REINFORCED CONCRETE IS PROPOSED WHICH RELATES MATERIAL DEGRADATION OF THE CONCRETE TO STRAINS IN THE REINFORCEMENT. THE REINFORCEMENT WILL BE DISTRIBUTED THROUGH THE CONCRETE TO PRODUCE A HOMOGENEOUS MATERIAL. THE MODEL WILL DISTINGUISH BETWEEN TENSION AND SHEAR CRACK BEHAVIOR -THE TWO MAIN MODES OF CONCRETE FAILURE. THE CONCRETE REINFORCEMENT INTERACTION WILL BE MODELED THROUUGH BOND STRENGTH REPRESENTATION IN TERMS OF AN INDEPENDENT COMPONENT IN THE COMPOSITE MATERIAL DESCRIPTION. THE MODEL WILL BE INCORPORATED INTO AN EXISTING COMMERCIAL FINITE ELEMENT CODE AND TESTED ON SIMPLE EXAMPLES.
