Paper Title:
Nonlinear Analytical Model of RC Shear-Critical Frame Elements
  Abstract

The beam-column element model for the nonlinear analysis of reinforced concrete frames is derived here. The transverse strains in stirrup direction are considered in the cross-sections. Analytical shape functions are used in the element formulation to eliminate the problem of shear locking. For the accurate consideration of shear effects, the constitutive models for the reinforced concrete in 2d stress state are adopted. Gauss integration method is used to integrate the resultant forces and stiffness. The analytical results of ultimate shear loads with different shear-span ratios show good agreement with experimental data.
