Comprehensive Benefit Evaluation And Analysis Of Shock Absorption Buildings

China is a country which is prone to earthquakes and has a wide range of seismic series.For example : the latest,late March 2022,Qinghai Province,a magnitude 6.0 earthquake.The main reason that causes earthquake disasters often like our country is that our country is in between two major earthquakes,that is,between the Pacific Rim seismic belt and the Eurasian seismic belt,so our country is a country with a high frequency of earthquake disasters.Earthquakes will also bring many secondary disasters,which will bring certain losses to human life safety and economy.Therefore,the disaster prevention and mitigation work in China is very important.At present,China has developed a variety of new technologies to improve the seismic capacity of building structures.Among them,the damping technology is a kind of method to improve the seismic capacity in practical engineering projects.The main principle of this technology is to install energy dissipation devices in the building structure,so as to reduce the influence of the huge energy brought by the earthquake on the building,and reduce the inter-story displacement of the building caused by the earthquake.Therefore,the use of seismic reduction technology can improve the seismic performance of buildings to a certain extent,thus ensuring that the adverse effects of disasters on society and lives are reduced to a corresponding extent.At present,the damping technology has been popularized to a certain extent,but the comprehensive benefit evaluation analysis involved is still lack of certain research,so there is no greater possibility to promote the application of damping technology.Therefore,establishing a comprehensive benefit evaluation model with rationality,science and creativity according to the characteristics of the research object can not only help China’s disaster prevention and mitigation level go up to a higher level,but also promote the development and application of earthquake mitigation technology.The main research work of this paper is as follows :Firstly,based on the difference between the damping structure and the traditional structure,from the perspective of sustainability,the environmental cost,loss expectation and casualties are discussed,and the calculation model conforming to the difference is established.Secondly,based on the seismic vulnerability analysis of IDA method,the SAP2000 software is used to establish the building calculation model,input the seismic wave,carry out the dynamic analysis,and finally output the structural response,namely the interlayer displacement angle of the structure.Thus the failure probability under different states can be calculated.Then,based on the characteristics of the damping building,from a sustainable point of view,as well as the difference between the damping structure and the traditional structure point of view,so that the three parts of the component can reflect the comprehensive benefit of the damping structure index system.Therefore,based on the characteristics of the research object,this paper decides to first use hierarchical analysis and entropy weight method to determine the weights comprehensively,and then use the object meta-topable evaluation method in constructing the evaluation model.Finally,using empirical analysis.In the actual case,the evaluation model for public shock absorption buildings constructed in this paper is used.After the analysis of empirical cases,it can be proved that the construction of the model in this paper is reasonable and scientific.Second,the evaluation model established in this paper can provide reference for other similar projects,and contribute to disaster prevention and mitigation in China to a certain extent,and promote the development of damping technology.
