Pulsation effects of wind to the antenna mast structures in software SCAD Office

Structural mechanics

The article is devoted to the calculation of antenna mast structures (AMS) using two different methodologies of adding pulsation wind load. The first method is implements the static theory of inertial loads applications. The second method a decomposition technique in vibrational mode (linear spectral theory), implemented in software SCAD Office. Analysis is performed on the requirements and recommendations contained in the current technical literature about communication structures. Comparison of the regulations of domestic and foreign standards by calculation of high constructions concerning directions of a wind and combinations of loadings which are necessary for considering at calculation of antenna mast structure (AMS) is executed. The calculation by two techniques for the two most common types of antenna mast structures (communication mast and communication tower) is performed in SCAD Office, and a comparison of results is made.
