What does the number of skirt base bolts depend on?
Thread Content
There is a device that is 6 meters tall (including the skirt base), with a diameter of 1600 mm; the thickness of its plates is 10 mm, and its weight is over 3 tons. It has 12 M27 anchor bolts. There is also one unit that is 10 meters tall, with a diameter of 2400; the thickness of its structural plates is 48 mm, and its weight is over 30 tons. It has 8 M36 anchor bolts. I feel there’s a problem with the design, so I asked the design institute, and they replied that there’s no issue. I just want to ask what determines the number of anchor bolts? Please, experts, give me some advice! !
It’s calculated, right? You can’t just look at the numbers
Diameter, height, wind pressure, various loads, etc.
Don’t always rely on what you think; you need to use calculations to refute others’ arguments. If you can’t even do calculations, how can you claim that there’s a problem with the design?
Do you think anchor bolts are used for fixing things? No, such large equipment usually has a self-stabilizing structure, which is designed to prevent it from toppling over due to lateral loads
Let facts and calculation results speak!
That’s because different people have different perspectives, and therefore think in different ways. The design is based on theoretical calculations; in theory, as long as calculations are done properly, the design should be fine. But the original poster compared two devices and wondered why the smaller device had so many bolts while the larger one had fewer Thus, two issues come to light: one is that the design considerations were inadequate; when self-stability calculations are successful, it is necessary to increase the specifications and quantity of certain large-scale devices in order to avoid giving the impression of something that is \"top-heavy\" ； Another point is that as the owner, you should base your decisions on facts rather than intuition; it’s not appropriate to make comparisons in this way, as designs can vary greatly from one person to another.
From the perspective of energy conservation and reduced consumption, it is unnecessary to add various additional elements in pursuit of sensory and visual effects, as long as safety can be ensured； Of course, users who are wealthy and careless enough can choose to increase the specifications. I once encountered a client who needed an air storage tank with a diameter of 800 mm, an operating pressure of 0.8 MPa, and a volume of one cubic meter, and they insisted on using a wall thickness of 16 mm.
If you can’t do it, then just study honestly. In a company with people like you, the leaders of the design firm look down on your company’s management；
Here, it mainly has a significant impact; after all, it’s only 6 meters tall, so there’s not much problem with squatting down.
With these devices, thanks to calculations, they should be able to remain stable on their own, so the placement of bolts can be determined more arbitrarily
