| Abstract. | Problem statement. At present, the effect of wind action on the structures being mounted is not taken into account. The pulsating component of the wind load is especially dangerous. The purpose of this study is to improve the methods for determining the dangerous zone of the tower crane operation near the facilities under construction, depending on the wind strength and the height of the mounting horizon. Results. The main results of the study are to determine the effect of wind speed, the pulsating component of the wind on the change in the danger zone of a tower crane, depending on the height of its work. The main structures used at the construction site are taken as the mounted loads: formwork, panels, floor slabs. Conclusions. The impact of the wind has a significant effect on the increase in the hazardous area of the crane operation. This impact increases with increasing windage. In order to reduce wind pressure, it is necessary to provide for measures to reduce the resistance of the surface of the load and prevent it from swinging. The coefficient was obtained in addition to the regulatory requirements for determining the hazardous area of the tower crane operation. The main types of cargo used at the construction site with high windage parameters are considered and their possible deviations during construction and installation work are determined by calculation. |
