A Finite Element Computer Program for the Prediction of the Behavior of Reinforced and Prestressed Concrete Structures Subject to Cracking

摘要

The report describes the theory, development, and application of the finite element technique to a computer analysis of reinforced concrete structural members. The analysis is applicalbe to both axisymmetric and planar structures and represents a significant improvement over previous analyses. The analysis accounts for the nonlinear behavior of concrete (in bi-axial stress states), concrete-steel bond, and steel (i.e., elastic-plastic response). The program predicts the states of stress and strain for the concrete, reinforcement and the bond existing between the two. Furthermore the program predicts the initiation and propagation of cracks in the concrete. (Author)
