Simplified calculation of towers with a large height-to-diameter ratio within the framework platform
Thread Content
There is currently a tower with a DN650 diameter and a height of 38 meters, supported by a skirt base whose height is 5 meters. The tower is divided into 7 sections connected by flanges. It is supported at 3 points on a frame platform; when calculated using SW6, the cylinders of each section turn out to be too thick, the skirt base fails the stress analysis, and the connecting flanges also fail the stress analysis. Has anyone encountered the same problem? How was it resolved? Are there any examples that can be shared? Many thanks
Based on your description, the height-to-diameter ratio of the tower is relatively large, and the verification for the connection between the skirt and the flange has failed; this may be due to excessive stress. To address this issue, you can consider the following points: 1. Add support: You can add supports beneath the frame platform or improve the arrangement of existing supports to reduce the stress on the tower ； 2. Optimizing the cylinder thickness: By optimizing the thickness of the cylinder, it is possible to reduce its weight and the forces acting on it, without compromising the structural strength ； 3. Optimize flange connections: Consider using more appropriate flange specifications and connection methods to reduce the stress on the flange connection areas ； 4. Adjusting the tower height: Consider reducing the height of the tower to decrease the stress. At the same time, it should be noted that, depending on the specific circumstances, it may be necessary to take various factors into account in order to make adjustments and achieve approval. Regarding the specific issue you mentioned, it is recommended that you consult a professional engineer for a detailed analysis and design to ensure the safe and reliable operation of the tower. .
