Default adding loading to old RSJ

I have just exposed the existing RSJs to which new load is to be

The BCO said the bearings may need to be exposed but has said nothing
more. For peace of mind I
probably need a structural engineer to check things, but can anyone
give a rough feel for the loadings here ?


Old fashioned RSJ, width 125mm, height 150mm, flange thickness 10mm at
the edges, 15mm at the web,
web thickness 10mm. Span is 2800mm. Can anyone tell me what type of
loads this beam can take (assuming bearings are OK). Also, what type
of point load could it take near the middle of the span ?


Thanks,
Simon.


Provided it's not rusty and full of holes - it will more than do the job. *I
have seen one half that size (height and width) and around 10 foot long
holding up two bedroom floors.

This was part of an old miners diy job when he knocked two rooms into one -
and when I asked if it would take the weight, he said that if that girder
was strong enough to hold the pit roof up, it'll certainly hold the bedroom
floors, even when I'm f*****g my wife (a very true tale by the way, those
Yorkies were tough then). LOL


Nice story ;-)
A very fine dusting of rust on the surface, overall seems very sound.
Trouble is, there may need to be almost a point load of 250kg on it
near the middle, but
I can add some support from a new wall that runs right under it.
I've got my first kiddy on the way and its making me a bit paranoid
about safety !
