The Aseismic About Extra-long Cylinder Latticed Shell With HDR Isolation

There are many earthquake zones in our country.In recent decades,earthquakes have occurred frequently in our country,causing incalculable losses to people’s lives and property.The destruction of buildings by a strong earthquake is devastating,and the lives of people in the building cannot be guaranteed.my country is one of the most severely damaged countries by earthquakes.The reticulated shell structure is a relatively common building in recent years.It has been welcomed by people for its large internal space and good seismic performance.More and more reticulated shell structures are entering people’s lives,and it is particularly important to improve the seismic performance of the reticulated shell structures.This article introduces in detail the origin,advantages and disadvantages and development history of the reticulated shell structure,as well as the development,structure and shock absorption principles of rubber bearings.In this paper,a detailed analysis of the mechanical properties,structure,working principle,and the advantages and disadvantages of the high-damping rubber bearing of the rubber bearing is carried out.Through the seismic response of five different bearing arrangement schemes under three different seismic waves,the principle and characteristics of the high-damping rubber bearing in the reticulated shell structure are explored.Three representative seismic waves were selected,and five reticulated shell structures with bearing arrangements were input to test the shock absorption capability of HDR rubber bearings.Multi-point input is used for seismic wave input,and the seismic response of the structure is closer to reality.If the rubber bearing can play a good role in the reticulated shell structure,then this design can be promoted,which can provide reference for the reticulated shell design and ideas for improving the structure.50 pictures;7 tables;43references.
