Abstract

The invention belongs to the technical field of civil engineering, and discloses a civil engineering damping device and a control method thereof. The civil engineering damping device comprises a signal acquisition module, a communication module, a central control module, a data analysis module, a damping control module, a comprehensive evaluation module, an abnormity early warning module, a powersupply module, a data storage module and a display module. The civil engineering damping device is simple in structure, rigidity does not need to be added to a main building structure, the problem that the initial rigidity of a damper is difficult to match with the lateral rigidity of the structure is effectively solved, the number of reinforcing bars of shear walls, beams and columns and the section size of components are reduced, and cost can be effectively saved; and the civil engineering damping device is suitable for anti-seismic windproof of a newly-built civil structure, has a good effect on anti-seismic reinforcement and post-earthquake maintenance of an existing building after an earthquake, is high in automation degree, reduces the workload of personnel, and can be used and popularized.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a civil engineering damping device and a control method thereof. Background technique [0002] At present, the anti-seismic structure in traditional civil engineering is mainly through the elastic-plastic design method, and the anti-seismic performance of the structure is used to achieve the effect of shock absorption. This method is a passive and negative anti-seismic countermeasure, because people are concerned about the future. The specific intensity and actual characteristics of earthquake disasters cannot be determined and evaluated. If the structure of the project is designed according to the traditional seismic method, it will not have the corresponding self-regulation ability. The safety performance requirements of the project, resulting in serious collapse or collapse. [0003] Through the above analysis, the existing problems and defects of the ex...
