Abstract

The invention relates to earthquake resistant multi-storey buildings or structures. The aim of the invention is to increase earthquake resistance by damping vibrations in various frequency ranges. A vibration damper in the form of a pool, partially filled with water, and massive slabs are installed on the floor or the upper floor. Massive plates are placed with gaps relative to the walls of the pool and among themselves. 4 il.

Description

The invention relates to construction and can be used in multi-storey buildings, structures erected in seismic regions with a hot climate.

The purpose of the invention is to increase the seismic resistance due to damping of oscillations in various frequency ranges.

FIG. 1 shows a seismic multi-storey building or structure; in fig. 2 shows section A-A in FIG. 1: FIG. 3 - the position of the elements of the vibration oscillations under the action of the horizontal load on the building or structure from right to left; in fig. 4- the same, under the action of a horizontal load on the building or structure from left to right.

A seismic resistant building or structure consists of a construction of 1 floors and a 2-vibrations quencher located in the upper part of the building or structure. The damper 2 oscillations is executed in the form of a pool 3 and massive plates 4. Pool 3 is installed and fixed on the floor 3 or on the floor 6 of the upper floor 7 of the building or structure and is partially filled with water 8. Massive plates 4 are laid loosely on the bottom of the pool 3 with gaps 9 and 10 relative to the walls 11 of the pool 3 and between themselves.

CeU multi-storey multi-storey building is tested as follows.

When a building or structure oscillates along with a pool 3, water B and plate 4, by virtue of their inertia, tend to maintain their original position, which causes a displacement of their main mass in one direction or another.

When this happens, the water 8 and plates 4 hit against the walls 11 of basin 3. In this case, the water 8 and plates 4 are displaced in antiphase with oscillations

4 WITH

g

The buildings or structures, with the plates A laid on the bottom of the pool 3, create the effect of friction, which leads to an increase in the damping of the building's vibrations, structures and improves dissipative properties. The damping effect is reliable in any frequency range of possible ground vibrations.
