Buckling restrained brace outrigger truss and composite shock absorption high-rise structure system
The invention relates to the technical field of energy dissipation and shock absorption of building structures, in particular to a buckling restrained brace outrigger truss and a composite shock absorption high-rise structure system. The buckling restrained brace outrigger truss is connected between an inner barrel and an outer barrel. Diagonal web members are non-yielding bearing type first buckling restrained braces and yielding energy dissipation type second buckling restrained braces which are arranged side by side, a multiple displacement and amplification type viscous energy dissipationmechanism comprises a cantilever truss, a toggle dual connecting rod and a viscous damper, and a composite shock absorption high-rise structure system is formed through combined application of the buckling restrained brace outrigger truss and the multiple displacement and amplification type viscous energy dissipation mechanism. The outrigger truss and the energy dissipation mechanism work cooperatively, energy consumption and rigidity mechanisms are diversified and coordinated, the shock absorption effect is obvious and effective, multiple fortification defense lines of the high-rise structurecan be achieved, the structure is simple, construction is convenient, and building space usability and economical performance are good.
