FINITE ELEMENT NON-LINEAR ANALYSIS OF CONCRETE STRUCTURES

The non-linear analysis of reinforced concrete structures using finite element techniques is presented. Tensile cracking, the multiaxial compressive response of concrete and the yielding of steel reinforcement are the main non-linear effects studied. Several models of multiaxial material behaviour, based on experimental data obtained elsewhere, are discussed. Isoparametric elements, under plane and axisymmetric conditions, are used throughout. Special elements are used to simulate reinforcement, liners, prestressing cables and jackets. These features were incorporated into incremental non-linear finite element programs which embraced both variable and constant stiffness methods of solution. Several realistic concrete structures are analysed and the solutions are compared with experimental evidence. (A). /TRRL/
