RSJ supporting pillars

[Jimbob12345]

Hi

A friend has just had a supporting wall knocked through. A structural engineer acquaintance has worked out the beam requirements, he has got a local builder to do the building work.
The building inspector wants to know the calculation for the supporting pillars. Which he does not have, as the structural engineer did the calculation as a favour and he is now unable to ask.

The supporting pillars are 3 inch brick from the previously existing wall. What is the calculation to work out what weight these pillars can take? We just need to know if we should be getting another SE in to check that the initial guidance was correct.

Any comments from structural engineers would be most helpful.

Weight is based on type of material holding up the beam and the area on which it is sitting, but there are other factors involved to make sure they pillars are actually going to stand up and not twist etc. The origonal SE should have designed the bearings and the pillars too. The beam is only half the job.

3" brick? You mean these walls are partition masonry walls? Or did you mean 105mm brick?

Why can't you just ask the SE that calculated the beam to calculate the piers?

The calculation is not about the weight, and you won't be able to DIY it
