Automatized structural optimization of lattice towers using realistic wind loads
Abstract eng: Due to the high number of structural elements and due to the fact that for different geometries different wind load approaches are necessary, lattice structures are difficult to optimize with respect to their shape and topology by manual methods. Therefore, a parametric description of trusses has been formulated to allow for an automatic design approach so that an object oriented optimization algorithm generates lattice structures as a finite element model automatically. Since the wind load is an essential factor for lattice structures wind tunnels tests were performed with the aim to cost-optimize the tower structures by taking into account direction dependent load coefficients and direction dependent wind velocities at the construction site. Based on examples it is shown that using both, the optimization routine and the result of the wind tunnel tests, more cost-effective towers can be realized.
