JOINING STRUCTURE OF STEEL COLUMN AND STEEL BEAM

摘要

PROBLEM TO BE SOLVED: To provide a column and beam joining structure eliminating the possibility of breakage of bolts or the like constituting a joining element on a joining part even in the case that large deformation is required on the joining part of a column and a beam supporting a floor slab. SOLUTION: A joining element 9 resists to shearing force and axial force mainly acting on the beam on the upper part from the center of a beam depth on a beam end by friction-joining a contact part by high strength bolts 14 after the upper and lower faces of a gusset plate 11 welded on a steel column 10 and the upper and lower faces of the beam upper flange 13a of a steel beam 13 attaching a concrete floor slab are sandwiched by connection plates 12, and is not joined to a steel column 1 on the lower part from the center of the beam depth.
