Abstract

The invention relates to a buckling restrained brace large cantilever structure system, and belongs to the field of structural engineering. The structure system comprises a concrete combined column, aspecial-shaped cantilever beam and a buckling restrained brace arranged between the concrete combined column and the special-shaped cantilever beam; and the concrete combined column and the bucklingrestrained brace, and the special-shaped cantilever beam and the buckling restrained brace are connected through assembled metal connecting pieces. The buckling restrained brace is adopted as a support member of the structure system, and the special-shaped cantilever beam is connected with a square-section combined column; and the whole anti-seismic performance of the large cantilever structure system is effectively improved by utilizing the good energy dissipation and shock absorption effects of the buckling restrained brace. All parts of components in the whole structure system are connectedin an all-bolt connection mode, the field welding work is reduced, the connection is safe and reliable, the field assembly degree is high, the construction speed is high, the construction quality iseasy to guarantee, and the comprehensive cost performance is greatly improved.

Description

Technical field

[0001] The invention relates to the field of structural engineering, in particular to a large cantilevered structure system supported by a buckling restraint system. Background technique

[0002] In recent years, the spatial structure system represented by the large cantilevered awning has become one of the most active areas of architectural structure development. Most of the stadiums, airports, railway stations and large theaters built in my country are large cantilevered structures with different shapes, which have the advantages of large span and light weight. The light weight and large span make their natural frequency close to the excellent frequency of natural wind, resulting in Its structure has the disadvantage of weak wind resistance. And most of them use ordinary steel support structures, their mechanical behavior is unstable, and the energy dissipation performance of the components cannot be effectively utilized. The seismic response of the structure sy...
