Abstract
The utility model belongs to the technical field of engineering seismic resistance and energy dissipation and seismic mitigation, and especially relates to a high-rise building structure equipped with outrigger trusses and having a function of energy dissipation and seismic mitigation. The outrigger trusses are set up along each direction of the top of an inner core cylinder of a high-rise building. Vertical outer frame columns are disposed under two ends of each top outrigger truss and at the periphery of the inner core cylinder. Damping elements are disposed between the tops of the outer frame columns and the top outrigger trusses. The damping elements are disposed between the tops of the outer frame columns and the top outrigger trusses, so the structure effectively reduces the damages from an earthquake to the system of a main structure, and optimizes the anti-seismic property.
Description
Technical field
The utility model belongs to earthquake resistant engineering, energy-dissipating and shock-absorbing technical field, particularly a kind of band semi-girder truss high building structure of realizing energy-dissipating and shock-absorbing.
Background technology
A kind of common structure form high-rise, super highrise building is inner core cylinder, peripheral sparse frame column, in structural top (likely comprising middle part), the semi-girder truss that rigidity is very large is set and connects inner core cylinder and external surrounding frame trestle.Inner core cylinder, external surrounding frame trestle, the acting in conjunction of semi-girder truss under horizontal loading (seismic load, wind load) effect, inner core cylinder mainly produces flexural deformation, and external surrounding frame trestle produces very large vertical tension and compression deformation under semi-girder truss role.Three's acting in conjunction, gives full play to the good Anti-pull-press performance of bending rigidity, external surrounding frame trestle that inner core cylinder is larger, jointly resists horizontal loading.
But as a kind of traditional structure form of highrise building, outter frame inner cylinder high building structure with semi-girder truss is after earthquake, because structural element will produce irreclaimable plastic strain, the mechanical property of member will change, make a large amount of structural element have to be replaced, even total faces the danger being removed.Multi-rise building structure is generally used in the core space in city, is undertaking important use function.A large amount of replacing structural element or dismounting are rebuild, and all will bring huge waste and pollution.Although safety that like this can support personnel, overall economic efficiency has been born huge risk.
Summary of the invention
The utility model provides a kind of band semi-girder truss high building structure of realizing energy-dissipating and shock-absorbing, has optimized highrise building with the semi-girder truss performance under seismic loading.
The technical solution adopted in the utility model is:
Top semi-girder truss is set up along each horizontal direction in the top of the inner core cylinder of highrise building; Below each semi-girder truss two ends, top, the surrounding of inner core cylinder, vertical housing trestle is set respectively; Between the top of described housing trestle and top semi-girder truss, damping element is set.
Described inner core cylinder is concrete tube, steel-concrete combined structure cylinder or steel structure frame support system cylinder.
Described housing trestle is one or more in concrete column, steel and concrete combination column, steel column, steel core concrete column.
Described damping element is one or more in metal lag return damper, viscous liquid damper, viscoelastic damper, frcition damper.
The beneficial effects of the utility model are:
In earthquake; inner core cylinder is main generation flexural deformation under seismic loading, and damping element will be because larger relative displacement plays a role between top semi-girder truss and housing trestle, dissipation seismic energy; effectively reduce the earthquake response of total, protect main structural element.Earthquake later primary structure member can not destroy or alleviate destruction, only needs to check, change damping element, can recover the use function of building.

Detailed description of the invention
The utility model provides a kind of band semi-girder truss high building structure of realizing energy-dissipating and shock-absorbing, below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, set up top semi-girder truss 1 on the top of the inner core cylinder 3 of highrise building along each horizontal direction; Below each semi-girder truss 1 two ends, top, the surrounding of inner core cylinder 3, vertical housing trestle 2 is set respectively; Between the top of described housing trestle 2 and top semi-girder truss 1, damping element 4 is set.
Inner core cylinder 3 is concrete tube, steel-concrete combined structure cylinder or steel structure frame support system cylinder.Housing trestle 2 is one or more in concrete column, steel and concrete combination column, steel column, steel core concrete column.Damping element 4 is one or more in metal lag return damper, viscous liquid damper, viscoelastic damper, frcition damper.
When earthquake occurs; as shown in Figure 2; inner core cylinder 3 is main generation flexural deformation under seismic loading; damping element 4 will play a role because of larger relative displacement between top semi-girder truss 1 and housing trestle 2; dissipation seismic energy; effectively reduce the earthquake response of total, protect main structural element.
