Abstract
This paper presents the simulation of the dynamic response of a slender building of 60 meter high submitted to wind. From theory of bridge aerodynamics this study was developed and to apply the theory for a tower structure, some small changes and assumptions has been made. To determine basic dynamic properties for the given structure, a modal analysis was conducted using SAP2000 software. A MATLAB script was made to perform all calculations using given and estimated input values to fit accelerations calculations for the two first translational modes. The script carried out time domain simulation for a single mode excitation of the structure by the previous calculation of their spectral densities.
