The behavior of building structure can be evaluated by distortional deformations of the foundations, being settlement monitoring of the build essential for this. However, interferences in monitoring data acquisition or experimental errors are common, generating uncertainties in the analysis. Thus, the objective of this paper is of determine the effects of settlement interpolation of uncertain or non-existent data to prediction the structural behavior of the building. A monitoring case was used for this purpose, where the settlement was systematically measured during the construction period in all pillars. In the analysis the settlement of monitored and strategically positioned pillars are disregarded. Subsequently, the settlement of these pillars is interpolated and the new configuration of the distortional deformations is calculated. It can be noted that the error in the distortional deformations increases with the number of interpolated points and the interpolation can generate a significant incoherence in the prediction of the structural behavior, even in the cases of few interpolated points.
