What is the purpose of the angle steel surrounding the outer wall of the storage tank?
Thread Content
As shown in the figure, it seems that all ordinary storage tanks have such a strip of angle steel around them. What is its purpose?
Wind-resistant ring, GB50341
Specifications are provided on reinforcement ring 47031; detailed data available
Are the wind-resistant ring and the reinforcement ring the same concept? The wind-resistant rings I’ve seen are all in a spiral shape, while the reinforcement rings are generally circular. Although both have a reinforcing effect.......
To enhance the rigidity of the tank, reinforcements are usually provided in thin-walled tanks
That should be a reinforcement ring, also known as a reinforcing strip, which serves to strengthen the tank wall. Only tall and slender structures require wind resistance measures; short and stout ones are not affected by ordinary winds. Wind resistance is achieved by eliminating the vortex street effect on the downwind side, and thick tanks do not generate vortex streets.
I agree with your view. The reinforcement ring is a steel plate, channel steel, or angle steel used to strengthen stress concentration areas; in simple terms, it serves the purpose of reinforcement. The wind-resistant ring has a continuous spiral shape, designed to disrupt the vortex effects caused by air flow and distribute some of the force to the ground. This is just my personal understanding; please correct me if I’m wrong
