Part of: Finite Element Analysis of Reinforced Concrete Structures II

Abstract:

The constitutive models used in the finite element analysis of reinforced concrete structures are presented from a number of different perspectives. The first part of this chapter presents fundamental experimental observations. This is followed by the descriptions of elasticity-based and plasticity-based models, together with discussions of strain-softening and its modeling. The fracture processes in concrete and the application of the recent finite block theory are then introduced. Finally, a state-of-the-art review of the recent developments in concrete plasticity from both its macro and micro approaches is presented.
