Problems solved by technology

[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 problems and defects of the existing technology are: the traditional anti-seismic structure in civil engineering does not have self-regulation ability, so it cannot meet the safety performance requirements of civil engineering, resulting in serious collapse or collapse
