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:- http://www.crewinblack.co.uk/celica/plan.JPG
I.E. The wall in question is an internal wall, there is one set of joists
running from the outside wall on one side of the house onto this internal
wall, likewise there is another set of joists running from the opposite
outside wall onto the same internal wall. The joists are only carrying the
floor of bedrooms, and a stud wall (almost directly above the wall in
question). There is no weight from the roof being transmitted down through
the stud wall.
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 ?
