Universal beam calculation Posted: Jan 18, 2006 10:57 AM Reply
Hi, I'm replacing a section (2.2m) of first floor internal suporting wall with a universal beam (2.5m). The beam will have to support floor joists, p/b, flooring only (no walls etc.) Rooms above whose floor joists will be supported by the universal beam (ub):
- have an area of 13.6 m2
- dead load (0.75 kN/m2) + live load (1.5 kN/m2) = 2.25 kN/m2
- load is 13.6 x 2.25 = 30.5 kN
- beam only suports half the load (one end of joists supported by wall so load is 0.5 x 30.5 = 15.25 kN
I've looked on the Corus site at
- buckling resistance for a 2.5m ub = 19.8 kNm
- Compression resistance for a 2.5 m ub: Pcx = 529 kN, Pcy = 222 kN etc.
Please can someone tell me what are the factors I need to look at to meet my loading requirements.
Thank you,
Neil
