Seismic isolation structure for high-rise building

Abstract

To mitigate the problem in which a lateral vibration of high-rise buildings during earthquakes increases with height, making taller buildings more vulnerable to earthquakes.SOLUTION: By suspending each floor 2 of a high-rise building from a beam of a column-beam 1 of a main body 1 on each floor of the main body, the floor vibrates with a delay after a lateral vibration of the column-beam 1 of the main body. This disperses the lateral vibration of an earthquake, resulting in improved seismic isolation performance.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] This invention aims to improve the earthquake resistance of buildings by suspending the floors of each floor of a building from upper beams, thereby mitigating lateral shaking during earthquakes. [Background technology]

[0002] The five-story pagoda, which has existed since ancient times, has five floors suspended from the top by a central pillar, which reduces lateral shaking during earthquakes and improves its earthquake resistance. Summary of the Invention [Problem to be solved by the invention]

[0003] The five-story pagoda is a single-pillar tower, so the floor area cannot be made large. Also, it is made of wood, so five stories would be too heavy to suspend using modern steel or concrete structures, both technically and economically. [Means for solving the problem]

[0004] This invention utilizes the vibration isolation performance of a five-story pagoda by suspending the floors of each floor from the upper beams of each floor, rather than placing the floors of each floor on the columns and beams of the main structure (including horizontal and vertical fires), and also makes the structure suitable for high-rise buildings both structurally and economically. [Effects of the Invention]

[0005] In this invention, when the main body of the building sways during an earthquake, the suspended floors sway laterally than the main body. Therefore, a sudden strong lateral sway causes a time lag between the main structure and each floor. Therefore, the sudden strong lateral sway is distributed over time between the main structure and each floor, and as a result, the lateral sway is mitigated. As a result, high-rise buildings built with this structure are earthquake-resistant. [Brief explanation of the drawings]

[0007] Figure 1 is a side view of a high-rise building, showing an example of how suspended floors on each floor shake during an earthquake. The direction of the shaking of the main body's columns and beams 1 and each floor 2 does not match because each floor is suspended. By dispersing the force of lateral shaking, lateral shaking is absorbed, vibration isolation is generated, and earthquake resistance is improved.

[0008] FIG. 2 is an enlarged side view of a portion of FIG. 1, showing the suspension points 4 of the wires on the columns and beams 1 of the main body of the suspension wire 3 and the suspension points 5 of the wire floors on each floor 2.

[0009] Figure 3 shows the location of the hanging wire 3 on the floor plan of the standard floor. The wire cannot be installed near the main body's column beam 1 because the wire will hit it due to lateral shaking. Therefore, a horizontal stopper or other part of the main body's column beam 1 is used as the hanging point 3. [Explanation of symbols]

Claims

1. A structure that suspends the floors of each floor of a high-rise building from the upper beams to reduce the horizontal force acting on the building during an earthquake.

2. A structure that reduces wind pressure on a high-rise building by suspending the floors of each floor from the upper beams.

3. A structure that reduces the vertical force acting on a building during an earthquake by incorporating springs into the wires that hang the floors of each floor of a high-rise building from the upper beams.
