Beam check
Beam check
(OP)
Newly installed valve is a ton heavier than the previous one and has a support pack located straight underneath which is welded to platform deck. As such, the deck beam which accommodates the valve support needs to be checked.
What I all have is geometry of that beam and new weight of the valve. Unfortunately, the other existing loads are unknown yet. What would you do in this case with this level of information? Would utilization factor give us something to play around? One of the cases would be to work out utilization factor of the beam for only new valve weight and then add the factor to global structural model.
Thanks in advance!

RE: Beam check
Alternatively you could figure out the allowable capacity of the beam, subtract the moment and shear caused by the valve, and then see if what remains is sufficient for an estimate of the dead and live load on the beam.

RE: Beam check
I think if i work out utilization factor of the beam in basis of the additional load added on the beam as the result of weight difference then the third party who possesses the general model can advise if this passes allowables in combination with existing loads. Am i beaing over conservative here?
Thanks for typing back btw.

Is this 5 percent general engineering practice or is there any references?
