Abstract: A finite-element analysis of reinforced concrete structures is presented. The solution is based on a two-dimensional analysis. The analysis includes the elastoplastic behavior of steel and concrete and the limiting tension criterion for concrete. The nonlinear problem is solved as piecewise linear one and introduced the effect of nonlinearities in material behavior by means of a stress transfer process. The results of the numerical examples are compared with the available solutions. It is emphasized that such a nonlinear analysis is necessary for a realistic stress distribution in reinforced concrete structures due to the redistribution of stresses resulting from the progressive cracking of concrete.
