Superposed wood-steel composite beam column structure

The invention discloses a superposed wood-steel composite beam column structure, and belongs to the technical field of building beam columns. The structure comprises stand columns and transverse beamsconnected to the stand columns, wherein the cross sections of the stand columns and the transverse beams are in the shape of Sudoku; the stand columns and the transverse beams are manufactured by stacking square timbers and rectangle-shaped steel, and are little limited by materials; the rectangle-shaped steel is conductive to the improvement of strength and stiffness of the beam column; and thesquare timbers are used for providing sufficient lateral rigidity for the beam column, have the lateral supporting effect on the rectangle-shaped steel, and avoid the premature buckling and instability of the rectangle-shaped steel in fire. The effective cross-section dimensions of the stand columns and transverse beams can be increased as required, so that the vertical and horizontal bearing capacity of the beam column is
