Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] see figure 1 , this embodiment is an assembled energy-dissipating outrigger structure system, including a frame column 1, a core tube 2, a leaf spring connector 3, an energy-dissipating shock absorber 4, a miniature buckling-resistant support 5, and a leaf spring viscoelastic damper 6 , Diagonal brace 7, I-beam I8, overhanging steel member 9, vertical support 10, I-beam II11 and column bolt 12.

[0045] see figure 2 , the core tube 2 is an offset core tube, and uneven deformation easily occurs between the core tube 2 and the frame column 1 .

[0046] see image 3 and Figure 4 , The frame column 1 is connected to the leaf spring connector 3 through the column bolt 12, and the leaf spring connector 3 is connected to the I-beam I8 through the energy dissipation shock absorber 4.

[0047] The energy dissipation shock absorber 4 can ...

Abstract

The invention relates to a fabricated energy dissipation extension arm structure system. The fabricated energy dissipation extension arm structure system comprises a frame column, a core tube and a pair of I-shaped steel beams I connected between the frame column and the core tube; a vertical support is arranged between the pair of I-shaped steel beams I; the middle of the vertical support is connected with an inclined strut and an I-shaped steel beam II; one end of the inclined strut and one end of each I-shaped steel beam I are in rigid connection with the core tube; the I-shaped steel beams I and the frame column are connected through steel plate spring connecting pieces and energy dissipation shock absorbers; and the I-shaped steel beam II and an outward-extending steel component arranged in the middle of the frame column are connected through a miniature buckling-restrained brace and a steel plate spring viscoelastic damper. According to the fabricated energy dissipation extension arm structure system, fabricated connection of the steel plate spring connecting pieces, the steel plate spring viscoelastic damper and the energy dissipation shock absorbers is used for extension arm connection of the frame column and the core tube, so that uneven deformation of the frame column and the core tube is relieved, the wind resistance or shock resistance is improved, and the structure safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic and energy-dissipating shock absorbers for engineering structures, and in particular relates to an assembled energy-dissipating outrigger structure system, which alleviates the offset core tube and frame through the assembled connection of a leaf spring viscoelastic damper and an energy-dissipating shock absorber. Uneven deformation of columns to improve the structure's earthquake and wind resistance. Background technique [0002] High-rise buildings with offset core tubes can effectively use space and gradually become an important form of high-rise buildings for commercial projects. However, the structural characteristics of offset core tubes will bring more difficulties to structural design optimization. During the research and development process of this new structural system There are some key technical difficulties and key scientific problems. One of the more prominent problems is the s...
