The VST (VLT Survey Telescope) is a 2.6 m class Alt-Az telescope to be installed at Mount Paranal in Chile, in the European Southern Observatory site. The VST is a wide-field imaging facility planned to supply databases for the ESO Very Large Telescope (VLT) science and carry out stand-alone observations in the UV to I spectral range. So far no telescope has been dedicated entirely to surveys; the VST will be the first survey telescope to start the operation in 2004, as a powerful survey facility for the VLT observatory. During the design phase a dynamic analysis of the telescope has been carried out using as inputs the data coming from the structural analysis of the mechanical system. This analysis has been used to build a model of the electro-mechanical system and to give an approximate estimation of the wind loading effect on the axes performance, based on the wind speed spectral model used at ESO.
