AI Technical Summary
Technical Problem
The existing steel frame-A-frame structure is difficult to construct and has limited shear deformation capacity when the diagonal bracing is connected to the steel beam, which affects the structural ductility.
Method used
A transition structure is set at the lower flange of the beam, which connects the diagonal bracing through the first web, the first transverse stiffener and the first horizontal stiffener, and an opening of the same height is opened on the web of the beam to form a high ductility connection.
Benefits of technology
It simplifies the connection between the diagonal brace and the steel beam, avoids weakening the shear deformation capacity, improves the ductility of the structure, and speeds up the construction process.

Abstract
The utility model discloses a high ductility steel frame-herringbone bracing structure, which relates to the technical field of building steel structures, and comprises a stand column, a beam and a diagonal bracing, the beam comprises a beam web, a beam upper flange and a beam lower flange, the diagonal bracing is connected with the beam through a conversion structure, the conversion structure comprises a first web, a first transverse stiffening rib and a first horizontal stiffening rib, the first web is arranged at the bottom of the beam lower flange and vertically aligned with the beam web, the first horizontal stiffening ribs are fixed to the bottom of the first web, the first transverse stiffening ribs are symmetrically arranged on the two faces of the first web, the inclined struts are fixed to the bottoms of the first horizontal stiffening ribs, and holes are formed in the beam web. The conversion structure facilitates connection of the beam and the inclined strut, the hole is formed in the beam web, the bottom elevation of the hole is flush with the conversion structure, the situation that the shear deformation capacity of the beam at the joint is weakened due to the fact that the conversion structure is additionally arranged can be avoided, and a high-ductility connecting structure is formed.
