Nonlinear Finite Element Analysis of Reinforced Concrete Beams with a Small Amount of Web Reinforcement under Shear
Engineering and Technology Journal,
2009, Volume 27, Issue 8, Pages 1485-1496
AbstractThis research work presents a nonlinear finite element investigation on the
behavior of reinforced concrete beams with a small amount of web reinforcement under
shear. 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 terminated at
the onset of crushing. In tension, a fixed smeared crack model has been used.
