Is there anyone who can help me with the sizing of a Hea beam?
I need to lift a hall building a few millimeters to be able to do some work on the foundation. I have 2 attachment/lift points, one at each outer corner. The hall building consists only of walls as everything else has been removed. I calculated what the building would weigh if it were solid pine walls and ended up at 2.5 tons. At the same time, not the full weight will rest on the lift points since the hall building also rests on a wall against the house. But if we calculate that each beam should handle 1.5 tons of load in the middle, the beam needs to be 3 meters long, and there will be 1.5 meters of free length/span between the points the beam rests on.

Hello,
15 kN provides a design moment of just under 9 kNm for a span of 1.5 m. A HEA 100 has just under 26 kNm in capacity, so even the smallest one is quite lowly loaded. However, what might be relevant is buckling of the web under the point load, which I don't have the same ease to review - but perhaps someone else can comment on that

It's a very small load so buckling is not a problemP patrikd84 said:Hi,
