How to calculate towers with tower hoops
Thread Content
For a tower equipped with a ring girdle, the bottom is supported by a skirt base, and the tower sections are connected using multiple sets of vessel flanges. The tower is of slender design; according to the calculations for conventional towers, the tower sections and vessel flanges would be quite thick. How should such calculations be carried out? Is there any standard that mentions such equipment?
The calculation shows that the tower sections and vessel flanges are very thick, which is a result of bending moments such as those caused by wind. 1. The latest version of SW6 includes a computational model with limit supports, which you can give a try. 2. Manually reduce the wind load, for example to 300, in order to decrease the additional bending moment. 3. For manually calculating the supporting force of limit mechanisms, refer to—Calculation of the horizontal force exerted by frame towers on the frame and discussion on the local stability of the tower—https://wenku.baidu.com/view/365469d280eb6294dd886c42.html
PV Desktop provides comprehensive analysis and calculation for tall structures with any number of lateral supports in towers and chimneys, including dynamic analysis of multi-support structures (multiple mode shapes), calculations for wind coming from the front and from the side, verification of axial stresses at critical sections, and fatigue assessment under lateral wind loads.
