Abstract
Computer code for design and optimisation of free standing lattice towers of wind machines is described. This uses a finite element model and implementation on a personal computer. The program uses a 3D beam element in Fortran language for lattice towers with rectangular and square base. The program is highly user interactive so that it can be used by any person with basic knowledge about engineering mechanics. After specifying the options and geometric parameters, the static analysis is carried out to get displacements and element forces. The element stresses are then compared with the allowable stresses using combined bending and axial formula until an optimum member sizes are obtained. The total weight of the tower is calculated. This package has been used for designing a tower for SAMIRA windpump.
