The stress state of a tank shell in the group under wind load

Monitoring and testing of buildings and structures

The distribution of the wind flow has been studied and its effect on the stressed state of the shell of a steel vertical cylindrical tank. Variants of wind pressure were considered for one tank and for a group of tanks. Aerodynamic coefficients are obtained for the considered variants in the SolidWorks software package. A physical experiment on a reduced tank model in a wind tunnel was conducted to verify the coefficients obtained. The stresses in the tank shell were determined by the finite element method using the SCADOffice calculation complex. The result revealed differences normative distribution of wind pressure from the pilot for single tank and located in the band. The most unfavorable version of the distribution of wind pressure for the tank located in the group was determined. The stress-strain state of the tank shell is compared under the normative and experimental wind load for the most unfavorable variant.
