Abstract: A method and an arrangement for supporting a first floor element at a beam and a beam. The beam is provided with a supporting flange section configured to support the first floor element. The method includes supporting the first floor element on the supporting flange section so that a first space is formed between the first floor element and the beam, providing elongated transverse fittings in the beam, providing transverse reinforcements to extend between the beam and the first floor element. The elongated transverse fitting have a first free end at the first lateral side of the beam, and a first protective element is connected to the first free end of the elongated transverse fitting outside the web section of the beam.

Abstract: A steel beam comprising a frame formed by a first web part, a second web part, a base plate and a horizontal top part. The first and second web part are arranged side by side at a distance from each other, and joined at a first end of the first web part and the second web part by the horizontal top part. The first and second web part are joined at a second end of the first web part and second web part by the base plate. The base plate, the first web part, the second web part and the horizontal top part are arranged to form a space that can be filled with concrete. The steel beam further comprises a hollow member arranged inside the space sealed to prevent concrete entering. The hollow member is attached to the frame for preventing movement in relation to the frame.
