Abstract: A series of pushover analyses on two-dimensional RC frames, part of an office building, are performed. They constitute a detailed parametric study, varying the number of stories and its height, and also the bay width. Regarding the stated objective, several commercial packages universally used in the design of civil engineering structures were used, namely SAP 2000, SeismoStruct and MIDAS. To represent the influence of the masonry infill panels, the equivalent tie method is used considering several values for the tie width. The influence of other parameters, on the structural behavior of the RC frame through a pushover analysis, is also analyzed: the confinement of the structural elements (columns and beams) and the length and location of the plastic hinges forming near the end of the structural elements. Finally, it is also parameterized the behavior of the structure when submitted to different load patterns, such as: uniform and modal, as suggested in the Eurocode 8, and triangular. Major conclusions of the study elaborated are presented and future developments are pointed-out in order to deepen the pushover analysis of two dimensional RC frames.
