Nonlinear Analysis of Three-Dimensional Framed Structures Using Smeared Crack Models

The nonlinear finite element analysis is used as a tool to obtain the behavior of three-dimensional reinforced concrete frame structures by utilizing constitutive models of reinforced concrete, called smeared crack models. Timoshenko assumption is adopted to permit the beam to experience shear deformation, which is an important feature in deep beam elements. Effect of geometrical nonlinearity which is significant in the beam with high slenderness ratio is also considered in this analysis. The validity of the present nonlinear finite element analysis is confirmed through the comparisons between the analytical results and the available experimental results reported in the literature
