I am trying to calculate the size of a steel beam.
I am removing 2.3 metres of a brick supporting wall, that is currently carrying two sets of 2.5 metre long joists.
I hope this picture explains:-
I want to use a 9 inch by 4 inch steel beam (for asthetic reasons), sitting underneath the joists mentioned above.
I need to calculate if a 9x4 is strong enough, and what "weight" or "rating" steel beam I need to order.
Can anybody offer me any advice ?
Thanks,
Paul.
