N2 - In this paper the possibility of defining low-dimensional models for the assessment of aerodynamic measures of tall buildings is investigated. In particular a model is proposed based on reconstructing the spectral structure of the floor loads commencing from a limited set of data consisting of the integral forces acting on a few 2-dimensional slices of the building. The validity of the method is then tested by comparing the variances of aerodynamic measures, such as base moments, estimated with the proposed model from a subset of information derived from wind tunnel tests to a reference solution obtained from the complete wind tunnel information. The possibility of employing the proposed model together with computational fluid dynamics (CFD), used as a means for estimating the integral forces acting on each slice, is then investigated with the ultimate aim of incorporating the proposed model in a CFD-based aerodynamic shape optimization scheme for tall buildings.
