    Abstract. The main issues related to the estimation of durability of cyclically loaded members of antenna-mast structures are considered in the article. The calculated fatigue curves in Russian and European normative documents used in determining the permissible number of cycles of variable loading of elements of construction metal structures are compared. Data on design fatigue resistances obtained on the basis of tests at cyclic loading mode of joints (connections) of antenna-mast structures members are provided. The substantiation of the necessity of dividing the pulsation component of the wind load into quasi-static and resonant parts is given. This makes it possible to determine the actual durability of cyclically loaded structural elements. The information provided in the article is recommended for use in the design of new and estimated residual life of safe operation of existing antenna-mast structures that have technological defects and operational damage of individual structural elements
    Key words: antenna-mast structures, estimation of durability, allowed number of variable loading cycles, design fatigue resistance, division of pulsation component of wind load.
