Can the number of fan-shaped roof panels be determined arbitrarily?
Thread Content
The vault structure of large storage tanks consists of a fan-shaped roof plate, ribs, and a central roof plate. May I ask how to determine the number of these fan-shaped roof panels? Can it be determined arbitrarily? As long as it’s an even number, that’s fine? Should it still be calculated based on the ribs?
This requires comprehensive consideration: first, to minimize the number of welds and thus reduce the welding workload; second, to facilitate welding by avoiding welds on the rib plates.
Is there a way to calculate it? I am working on my graduation project
Additionally, the size of the plate must also be considered, and there is no calculation method for this.
Taking into account factors such as plate width, material utilization rate, and number of welds, the minimum distance between welds on the roof slab shall not be less than 200 mm.
Is the width of the fan-shaped plate selected according to the specifications?
Generally, endian cross-cutting should be considered to improve material utilization. Design drawings usually specify a basic dimension, but this can be adjusted or modified according to specific circumstances.
The height of the wall panels, including those with different thicknesses, can be adjusted as appropriate according to actual conditions, provided that design approval is obtained.
