The behavior of the mast is non-linear due to its slenderness and compliant
guy-support system, having a tendency to lose stability and even crush
suddenly. Wind load is one of the main factors affecting the stability of the
structure of the mast. Structural assessment of the different mast
configurations has been investigated in the past. Furthermore, European
standards EN 1993-3-1:2006 and EN 1993-1-6:2007 already provides some
guidelines about the basis of structural analysis of masts and towers. This
paper presents the results of numerical simulations of a guyed mast exposed
to wind action using finite element method. Structural analyses were
performed for three different constant wind loads, modal analysis provides
the values of natural frequency and mode shapes, while the stability analysis
was performed for the first three buckling load factor values. The motivation
for this study is to investigate the contribution of finite element method to
structural analysis of a lattice structure such as guyed mast as an
alternative and/or improvement to the literature and codes.
