Column skirt shell
Thread Content
May I ask that there are two types of skirt shells for tower containers; what situations are they suitable for respectively? What are the requirements?
That is, in what situations are cylindrical and conical skirt shells applicable respectively? What are the requirements?
Cylindrical shapes are commonly used, while conical shapes are generally applied to towers with small diameters. A conical skirt can solve this problem when the tower diameter is small and the calculated number of foundation bolts is large. ,
The skirt shell forms are divided into two structural types: cylindrical and conical. Generally speaking, provided the conditions permit, cylindrical skirt shells should be used as much as possible, as they have a simple structure, are easy to manufacture, and exhibit reasonable stress distribution. When tower-type containers are in the following situations, a conical skirt shell should be considered: 1) The design calculations require a large number of foundation bolts; it is difficult to arrange them in a cylindrical pattern, and it is necessary to maintain a certain spacing between the foundation bolts ； 2) The thickness of the skirt shell is sufficient, but the design calculations require an increase in the cross-sectional moment of inertia of the skirt shell ； 3) Due to the large wind loads on tower-type containers, the compressive stress on the concrete foundation beneath the skirt base ring exceeds its allowable limit; therefore, it is necessary to reduce the compressive stress acting on the top surface of the concrete foundation.
The standard definition of tower containers is explained very clearly
The explanation is very clear! Thank you! ! ! ! ! !
