Introduction to build-in beams

Build-in beams are often used to place the floor slab on the bottom flange in order to optimize the free height in a building. The build-in beams are of the types SFB (Slim Floor Beam), IFB (Integrated Floor Beam) or THQ (Top Hat Beams).

The procedure for insertion of a build-in cross-section into a project is identical with the procedure for any other cross-section type; the user just have to specify the type in the type-selection dialogue, then choose the appropriate shape and size, and oversee or change the required parameters.

As for any other cross-section type, the sectional characteristics such as sectional area, moment of inertia, position of centroid, etc. are calculated automatically by the program. The user may input or modify other cross-section parameters such as material, name, etc.
