Modelling and Analysis of Lattice Towers for Wind Turbines

Amlan Das, Dr. Shiva Kumar

Abstract: Towers are the fundamental support structures for wind turbines which give them the suitable height to capture wind. Lattice towers are freestanding framework towers which have found applications in transmission towers, cellular towers, radio towers, observation towers and wind turbine towers. This paper discusses about both guyed and freestanding lattice towers. The lattice towers are modelled in three different shapes and two different sections (Pipe and Angle). The models are designed and analysed under static and dynamic conditions in STAAD Pro software. The objective is to produce a safe, stable and optimum design. The results are compared and suitable conclusions drawn.
