NONLINEAR ANALYSIS OF REINFORCED CONCRETE STRUCTURES

Hereby a procedure for the nonlinear analysis of reinforced concrete frames taking into account the nonlinear properties of materials and second order effects, is briefly described. This method is based on a matrix analysis of the structure with elements of variable-stiffness distribution. The stiffness law is defined in accordance with the mechanical properties of the section, the bending moments distribution and the corresponding moment-curvature relationship. This system fulfills the equilibrium and compatibility conditions in all the sections and would be equivalent to a very close discretization. Finally, an example is shown in order to indicate the significance of different discretization methods on moments and deflections results. For the covering abstract of the conference see IRRD 288957.
