In this study, several numerical experiments are performed through the use of ReConAn Finite Element Analysis (FEA) software. These experiments involve the numerical assessment of the nonlinear behavior of reinforced concrete (RC) structures under limit state loading. The main objective of this research work, is the development of an object-oriented FEA code (ReConAn FEA), capable of easily incorporating advanced numerical techniques and modeling methods for the analysis of RC structures through the use of state-of-the-art programming techniques. An excessive literate and numerical research...
