User's Guide: Fracture Mechanics Analysis of Reinforced Concrete Beams (FMARCB)

Abstract

A finite element package has been developed to perform nonlinear fracture mechanics analysis on reinforced concrete beams. The system consists of a graphic input/output interface and analysis routines using finite element techniques. Fracture Mechanics Analysis of Reinforced Concrete Beams (FMARCB) is a two-dimensional finite element program with triangular, isoparametric, bar, and interface elements. The system uses the discrete crack approach with a fictitious crack model to represent tensile concrete softening; a confinement concrete model to characterize compression softening; a nonlinear bondslip constitutive model for the bond-slip phenomenon, which is degraded when cracks form across the tensile reinforcement; and an elastic, perfectly plastic constitutive model to represent the yielding of the tensile reinforcement.
