A composite-structure building framework, which comprises horizontal steel girders (21) and vertical steel columns (12), which have been joined together with bolts (14). The vertical column (12a) has been placed from above against the bottom (22) or side flanges (27a) of the horizontal girder and fastened to the lower column (12b) at the corresponding point with bolts (14) going through the bottom (22) or the side flanges of the horizontal girder. Concrete reinforcements (19) are, if necessary, placed both in the U-shaped trough or box formed by the horizontal girder and inside the columns, and these spaces are filled with concrete. |
