ABSTRACT:
A built-up support member for carrying bending loads is used in building construction. The support member is formed of two separate elements (1, 2), one superimposed on the other. The separate elements absorb normal forces caused by bending loads. One of the elements (2), for example formed of concrete, acts in compression, while the other acts in tension. Shear forces must be transmitted between the separate elements. Shear transmission surfaces afford a positively locked connection of the separate elements. The shear transmission surfaces include cooperating and complementary shaped projections and recesses. In addition, clamping elements (15) are provided between the separate elements in a prestressed manner.
