IMPROVEMENT OF WIND PRESSURE CALCULATION OF GUYED MASTS CONSIDERING THEIR LOCATION ON BUILDINGS ROOFS
Guyed masts for cellular nets are often on roofs of buildings placed. This article reviews the research results of wind stream properties over a building surface in the wind tunnel. Importance of this research is highlighted. The open soaking up wind tunnel of short type was for the experiment used. An overview of the main parameters of a wind tunnel and of the used measuring devices is given. Measurements of wind pulsing speeds without the building model and with the considered model of a building were carried out. There are the profile of average speed of a wind, the profile of intensity of turbulence, the profile of spectral density for all high rise points of a profile depending on frequency, the profile of specifying factor of average wind speed amplification received. Improvement of a wind pressure calculation procedure for the guyed masts located on a roof of buildings taking into account caused by own aerodynamic properties wind pressure increase over a building is offered.
