Problems solved by technology

Therefore, if the "laminated rubber seismic isolation bearing tensile structure" described in the above-mentioned patent application is used in the seismic isolation of high-rise buildings, creative work will be done, because: 1. If all the seismic isolation layers of high-rise buildings are used It is obviously a waste to replace ordinary seismic isolation bearings with shear-resistant and tensile-resistant se

Example Embodiment

[0027] Example 1

[0028] In this embodiment, a high-rise building with a square cross section is taken as an example to describe in detail the application of the seismic isolation method of the present invention. See figure 1 with figure 2 In this example, each floor of the high-rise building has 25 rooms, which are distributed in the form of 5×5; the space between the bottom of the first floor of the high-rise building and the foundation is the seismic isolation layer. According to the above-mentioned structural characteristics of high-rise buildings, the specific seismic isolation method adopted in this embodiment is as follows:

[0029] 1. See Figure 1 ~ Figure 6 with Figure 8 In the seismic isolation layer, among the 6 beams 12 perpendicular to the periphery of the high-rise building on each surface of the upper structure, the two in the middle are selected as the seismic isolation structural beams 3. The axis of the seismic structure beam 3 is on a straight line with th...

Abstract

The invention discloses a seismic isolation method for a high-rise building. The method is mainly composed of the following steps: at least one cross beam (12) intersecting with the periphery of the high-rise building is selected in the middle of each surface as the seismic isolation structural beam at the periphery of the upper structure. (3) A special seismic isolation beam (4) parallel to the seismic isolation structure beam (3) is arranged directly under each seismic isolation structure beam (3), and a tie rod (1) is respectively fixed on both sides of the middle of each seismic isolation structure beam (3). ), the two tie rods (1) extend vertically downward to the lower part of the special beam (4) for seismic isolation respectively, and are respectively connected with one end of the horizontal bar (2); corresponding to the directly below each column (13) of the superstructure A first column pier (8) is provided, and a second column is provided directly below the beam (12) corresponding to the lower part of the shear wall (14) of the superstructure, except for the special beam (4) for seismic isolation A pier (9), each of the first column piers (8) and each of the second column piers (9) is provided with a vibration isolation support (7).

Description

technical field [0001] The invention relates to buildings capable of withstanding or protecting from earthquakes, in particular to a method for seismic isolation of buildings. Background technique [0002] The seismic isolation structure is a layer of flexible isolation layer with sufficient reliability set between the upper structure and the lower structure of the building, which is used to block the transmission of seismic waves to the upper structure. Studies in recent decades have shown that seismic isolation technology is one of the most effective methods to reduce the seismic response of seismic structures and avoid structural damage and collapse under earthquakes. At present, seismic isolation technology has been widely used at home and abroad, and has experienced many major earthquake tests. However, the current application of seismic isolation technology in practical engineering is mostly to control the horizontal seismic response of structures, that is, for struct...
