EXPERIMENTAL STUDY ON THE EFFECT OF FOUNDATION CONFIGURATIONS ON DYNAMIC RESPONSES OF WIND TOWER

This experimental project is to study on the effect of foundation for offshore wind tower on dynamic responses due to wind load. Power Spectral Density (PSD) is developed as spectrum energy from acceleration motion of structure in order to determine the effect of foundation configurations. The characteristics of offshore support structure could be described on the spectrum energy during applying wind load. The experimental study is required to collect the acceleration motion of structure before developing spectrum energy by using MATLAB software in order to analyze a characteristic of structure due to the effect of structure from wind load and provide offshore model of wind tower including controlling all environmental factor during testing. The fabrication of offshore wind tower model is to construct with a scale down from actual wind tower. There are three types of foundation which are involved in this experimental study such as monopile, tripod and jacket foundation. The effect of foundation configurations could be developed as the preliminary design. Dynamic responses will be measured at the wind tower and offshore support structure in order to produce the effective data collection and enhance dynamic analysis of foundation in this study.
