The present paper deals with the application of robustness criteria to special structures used in telecommunications, the steel lattice masts. Although progressive collapse is considered a widely familiar term and most engineers have heard of well-known events of this type of failure, such as the accident at Ronan Point in London, or the collapse of the towers of the World Trade Center in New York, there is not much progress made towards the quantification of the problem. The goal of this paper is to apply a method, proposed by the authors, of quantifying robustness to steel lattice masts and investigate the behavior of the structure in view of robustness. For the purpose of this research activity a typical and very common type of steel lattice mast regarding its geometrical and structural characteristics is used, whereas all the parameters of the study are presented and thoroughly described.
