This work aims to verify soil-structure interaction (SSI) influence in a high building employing iterative process between CAD/TQS and GARP programs carried out by Bahia (2015). The analysis was performed on a residential building localized in Águas Claras/DF, which presents settlements measurements and loading tests. The work began with modeling the structure, using the CAD/TQS program, considering the rigid supports. With the results of the efforts, the effects on settlements were calculated using GARP software. It was then carried out a retrospective analysis of the structure requirements, with a flexibilization of support data recovered by GARP. This iteration was performed until the convergence of results of load and settlement was achieved. The effects of the ISE were verified for the first floors of the building. The largest variations were the normal stress (Fz) of 0.7 kN in P216 at the end of the 2nd floor; from the moment in x (Mx) of -118.3 kN.m in P216 at the end of the 1st floor and from the moment in y (My) of -0.7 kN.m in P221 at the end of the 1st floor. In the settlements, the results were closer to the monitoring settlements after SSI. However, the average relative change is still high, reaching -38.9%. The results have shown to be satisfactory, as recent research indicates a similar decrease of settlement when considering the SSI, besides the increase in stresses.
