Antiseismic-collapse self-vibration-reducing structure

Abstract

The invention discloses an antiseismic-collapse self-vibration-reducing structure. A shaking component is distributed at the local part of a bottom layer of the structure. The left part and the right part of the shaking component correspondingly support supporting columns or a wall at the upper part, and / or the front part and the back part of the shaking component correspondingly support the supporting columns or the wall at the upper part; the shaking component is in rigid connection with a cantilever beam, the cantilever beam is placed on a base top, the cantilever beam is restrained to sideslip relative to a base, and the rigidity of a structural bottom layer is weakened and form a structural system which can shake locally; and the shaking component shakes when the shaking component is pushed by a surround structure and involves the supporting columns or the wall supported by the shaking component in being lifted, fallen and vertically and relatively moved. By means of the antiseismic-collapse self-vibration-reducing structure, the self-vibration-reducing function of the structure can be achieved, and the antiseismic-collapse capacity of the structure is effectively improved.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of structural engineering, in particular to a self-damping structure anti-seismic collapse. Background technique [0002] The development of anti-seismic design technology for building structures generally goes through two approaches. One is to improve the ability of the structure itself to resist earthquakes, such as the development of high-performance materials, components and structural systems, etc.; the other is to control vibration to reduce the seismic excitation response of structures. Set up energy dissipation dampers for energy dissipation and vibration reduction, and foundation vibration isolation, etc. Energy consumption and vibration reduction and vibration isolation are not necessarily distinct in practice, and vibration control in engineering often contains these two concepts and technical measures at the same time. [0003] In the existing technology, there is a targeted rel...

Problems solved by technology

[0004] Compared with the traditional structure, the rocking structure greatly reduces the energy input of the earthquake to the structure, and has the ability of self-damping and self-resetting; however, the seismic deformation of the weakened part of the rocking structure is relatively large, and often includes structural or non-structural accessories, such as Rubber bearing vibration isolation foundation, energy dissipation elements or applying unbonded prestress, etc., need more careful design, construction and maintenance
