Abstract:
This paper proposes a reliable and computationally efficient finite-element model (Partial
Fiber Model) for the nonlinear analysis of reinforced concrete (R/C) frames under static and cyclic loading conditions that induce multiaxial bending and axial forces. The beam-column member is
composed of three parts: middle elastic and two plastic regions at the two ends of beam. The plastic regions are discretized into longitudinal steel reinforcement and concrete fiber elements. The
nonlinear behaviors of the elements are derived from the nonlinear stress-strain relations of the steel and concrete fibers. The global stiffness matrix of beam-column can be deduced from those of
mentioned three parts. Numerical examples are calculated to prove the accuracy and efficiency of the model. The results of nonlinear analysis show the validity of the model to describe the nonlinear
response of frame subjected to static and cyclic loadings.
