Nonlinear Finite Element Analysis of High Strength Fiber Reinforced Concrete Corbels
Engineering and Technology Journal,
2008, Volume 26, Issue 1, Pages 1-15
AbstractThis research work presents a nonlinear fini te element
investigation on the behavior of high strength fiber reinforced concrete
corbels. This investigation is carried out in order to get a better
understanding of their behavior throughout the entire loading history.
The three- dimensional 20-node brick elements are used to
model the concrete, while the reinforcing bars are modeled as axial
members embedded within the concrete brick elements. The
compressive behavior of concrete is simulated by an elastic-plastic
work-hardening model followed by a perfectly plastic response,
which terminate at the onset of crushing. In tension, a fixed smeared
crack model has been used.
