FEM model for reinforced concrete frames loaded by seismic forces

Objective of the presented research is the formulation of one enough sophisticated and, for engineering practice, convenient finite element method (FEM) based numerical model for reinforced concrete frames loaded by seismic actions. For modeling of concrete and steel nonlinear behavior uniaxial constitutive rules are applied. The proposal for inclusion the frame joint deterioration, as well as, interaction of shear and flexural forces (inclined cracks effects), in this model, is given additionally. The results of few numerical tests (linear/nonlinear analysis of reinforced concrete frame loaded by three seismic actions) are given as an illustration of presented theoretical research.
