Latticed towers are used in several industrial activities due to the fact that they are a relatively inexpensive and a reliable structure. In places where the maintenance could be an issue, such as cold weather countries, there is an active research activity to develop latticed towers made of new materials such as composites. Currently, in the University of Manitoba a research about developing FRP (fibre reinforced polymers) latticed towers is being carried out by Dr. Dimos Polyzois. Part of this research is to perform a finite element analysis (FEA) of a steel lattice tower in order to be able to compare the behaviour depending on the type of material used. This project has performed a finite element analysis (FEA) of a steel latticed tower. This analysis was made using two types of models (i.e. truss type elements model and beam type elements model). The difference between the results of both models is about the 20%. Several load cases were analysed in order to get a better understanding of the behaviour of the tower. The maximum displacement (388.138 mm) is obtained with ice on the tower and wind angled 30 degrees from the perpendicular of a face. The maximum stress in the tower is about 76.708 MPa and the maximum force of the cables (12.1 kN) is about the 70% of its breaking strength.
