Resumo (PT): The design for structural stability of reinforced concrete frame buildings, taking in account second order effects is, in the available codes, (CEB,1990,EC2,1989), based on simplified, but lengthy, methods, resorting very often in inadequate solutions. A critical analysis of existing codes is performed, in order to define a satisfactory model for the material behaviour and aiming to obtain more realistic rules for the design. For that purpose a computer code, which includes geometric and material non-linear effects, was implemented on a personal computer. The overall non-linear solution is solved by the Newton method, together with the arc-length method, therefore permiting the variation of the load increment during the iterative process to improve convergence
