I would like to ask everyone: can the support height of leg-type supports be very small?
Thread Content
JB/T 4713-1992 Part 2: Leg-type supports, Table 2 – for tanks with a diameter of 1.4 m, the maximum supporting height is 1.1 m. I think setting the support height at 300mm would be fine, right? Is calculation and verification required? Xiaobai doesn’t quite understand; I’m asking for everyone’s help.
Sure. It can be short, but not long. Your standards need to be updated.
Sure. The standard specifies the maximum support height; as long as it’s not higher than that specified value, it’s acceptable
The standard specifies the maximum value; as long as it does not exceed this maximum, it is acceptable. Additionally, the latest standard is NB/T47065.1~5-2018
It should be low, not high; it affects the changes in the bending moment of the supports
It is possible to use a shorter duration; the shorter the duration, the larger the stress reduction factor, and thus the greater the stress exerted on the steel member with the same cross-section
