000010885 520__ $$2eng$$aThe use of non-linear static procedures on seismic analysis of structures, mainly pushover-based ones, has recently known considerable developments. On that matter, studies that have been carried out focus mainly on issues that are related to the computation of an equivalent SDOF structure and consequent conversion of the pushover curve. However, equally relevant are the modeling aspects of the original structure, which influence the MDOF unchanged pushover curve. It is commonly accepted that two major modeling possibilities are considered when non-linearity is on steak: either a fibre-based model, with non-linear models for steel and concrete or non-linearity concentrated on plastic hinges located at elements’ extremities. The present paper aims to go through different modeling possibilities, using a set of different building frames, discussing its application and their relative effects on final results, obtained by assessment on the basis of non-linear static analysis. Therefore, using both possibilities, a direct comparison of the achieved pushover curves is performed. Conclusions are set towards the establishment of relative advantages and/or limitations, if relevant, coming from the choice for each of the modeling possibilities.
