A tower is a super structure with a framework which is built in order to fulfil the need for placing objects or person at a certain level above the ground. They can be used as electricity pylons, as a communication tower and to support a wind turbine.

A renewed commitment to power generation from clean sources, such as wind, along with the recent deployment of turbines of various sizes that rises to new heights, makes obtaining the most efficient and safe design of the structure that supports them “Towers” ever more important

The aim of this project is to analyse and design a steel tower that will support a wind turbine structure for University of Ilorin. The objectives of this project are:To obtain an estimate of the wind speed in University of IlorinTo collect information about turbine weight To model the steel tower using STAADProTo carry out a complete analysis and design of the tower using MIDASGenTo obtain the deflection at the top of the tower

The scope of this project is the analysis and design of a three-legged, self-supporting lattice tower for University of Ilorin with the assumption that hinge connection exists between the members with no consideration for the vibration generated by the wind turbine.
