Guyed masts response to wind action, ice load and thermal action has been analysed in this paper. Computational model of wind action based on quasi-steady theory has been applied. It has been assumed that nodal displacements may be expressed as a linear combination of representative mode shapes. Special computer program has been made to allow analysis of such structures. It has been found that the selection of representative mode shapes is very influential on the calculations outcome. The obtained results have been compared with the ones calculated according to patch loads method presented in Eurocode 3. The dynamic part of forces calculated with own method are about half of the ones coming from the standard.
