Novel shock absorbing and collapse preventing cylinder structure

Abstract

The invention discloses a novel shock absorbing and collapse preventing cylinder structure, and belongs to the field of structural engineering. The novel shock absorbing and collapse preventing cylinder structure comprises a frame structure, a wall-stairway combination system and dampers. A wall is rigidly connected with a lower frame beam, flexibly connected with an upper frame beam and flexiblyconnected with frame columns, and the dampers are arranged between the wall and a frame. Stairways are in ductile connection with the wall and are disengaged from the frame structure, and the dampersare arranged between stairway beams and stairway section plates. According to the wall-stairway combination system, the weak shortcoming between the stairways can be overcome, and energy dissipation is yielded through the dampers under a small earthquake; the stairways can be disengaged from the main structure under a large earthquake, thus staircases are prevented from collapsing, and the escapefunction of the stairways is ensured; and the novel shock absorbing and collapse preventing cylinder structure can be applied to multi-layer frame structures and small high-rise frame structures, structural stiffness is evenly distributed advantageously, and the dual lateral force resistance system with the functions of energy dissipation, shock absorbing and large-earthquake collapse preventing is achieved.

Description

technical field [0001] The invention belongs to the field of structural engineering, and in particular relates to a shock-absorbing and anti-collapse cylinder structure. technical background [0002] In the traditional structure, only the vertical load of the stairs is considered, and the anti-seismic design is not carried out. As a result, in major earthquakes, most of the stairs that should be used as escape routes are seriously damaged, causing huge casualties. Moreover, under the action of an earthquake, only considering the detachment of the stairs from the main structure does not necessarily guarantee the integrity of the stairwell. Under a stronger earthquake, the stairwell may collapse in whole or in part. At the same time, the stairwell of the traditional structure is relatively weak, and the stress concentration is concentrated at the corner of the structure under the action of the earthquake, so it is not suitable to set the stairwell of the escape passage at the ...

[0002] In the traditional structure, only the vertical load of the stairs is considered, and the anti-seismic design is not carried out. As a result, in major earthquakes, most of the stairs that should have been used as escape routes were seriously damaged, causing huge casualties

Moreover, under the action of an earthquake, only considering the detachment of the stairs from the main structure does not necessarily guarantee the integrity of the stairwell. Under a stronger earthquake, the stairwell may collapse in whole or in part

At the same time, the stairwell of the traditional structure is relatively weak, and the stress concentration at the corner of the structure under the action of the earthquake is not suitable for setting the stairwell of the escape route at the corner, which hinders the architectural design.
