Reinforced Concrete Finite Element Modeling based on the Discrete Crack Approach
Abstract: The behavior of
reinforced concrete elements is complex due to the nature of the concrete that
is weak in tension. Among these complex issues are the initial cracking and
crack propagation of concrete, and the bond-slip phenomenon between the
concrete and reinforcing steel. Laboratory tested specimens are not only
costly, but are limited in number. Therefore a finite element analysis is
favored in combination to experimental data. The finite element technique
involving the cracks inserting is one of the approaches to study the behavior
of reinforced concrete structures through numerical simulation. In finite
element modeling, the cracks can be represented by either smeared or discrete
crack. The discrete crack method has its potential to include strain discontinuity
within the structure. A finite element model (FEM) including the concrete
cracking and the bond-slip was developed to simulate the nonlinear response of
reinforced concrete structures.
