Horizontal container calculation
Thread Content
When calculating horizontal containers, should the mass of the attachments include the mass of the saddle? Just add the quality of the take over, flanges, manhole ladders, and platforms!
Personally, I think the weight of the support should not be included. Just kidding: if you’re carrying someone, calculate whether you can carry them – do you also need to include your own weight? (It might not be appropriate to make this joke; please forgive me):P
It should be included, with the purpose of calculating the weight of the steel in order to determine the cost.
The mass of the attachments is used in the calculations for the saddle; the mass of the saddle itself does not need to be included. Other ladders do need to have their mass taken into account, while for the access manholes, it’s not necessary to include their mass. It’s important to take into account the weight of the water used during the hydraulic test – that’s the significant factor here. The others all have small heads
Calculated according to the standards, the saddle is used for support. Should be calculated
Of course it has to be included; the saddle is part of the equipment and cannot be removed
It must be included, because the weight of the saddle itself also plays a role when calculating the force on the saddle bolts. As for the moment of inertia of the saddle section used in calculating the saddle support, it is also calculated based on the smallest end of the saddle.
The support is also part of the equipment.
