| With the development of economy and society,the process of urbanization is speeding up.In order to solve the people’s demand for housing and commercial activities,ultra long buildings and high-rise buildings are increasingly widely used in urban construction.At the same time,in the process of urban construction and wide application,we should not neglect that China is a country which is facing the threat of earthquake and the earthquake disaster.The super long building and super high building are not only subject to a large number of loads,the structure is extremely complex,how to build high-rise buildings in high seismic intensity region is a key problem for structural engineers.In order to minimize the damage caused by the earthquake,many scholars around the world have done a lot of research on the earthquake resistance of buildings.Study the seismic design of the structure is carried out with buildings and gradually developed,most of the building structure is through the seismic design of different degrees after built,it can be said that the seismic structure is one of the world’s largest number of structures.Although the seismic structure has a very important role,but the biggest disadvantage of the seismic structure is quite obvious.At the time of the earthquake,some members of the structure will be destroyed,and it will cost a lot to repair the earthquake.In particular,the earthquake caused by the loss of the structural components of the building,often lead to the loss of its original building construction function,resulting in huge economic losses and waste of resources.In order to improve and make up for the deficiency of the seismic structure,the isolation structure and the damping structure are developed.The good performance of isolation technology in some big earthquake it is a very effective damping means,has been increasingly used in practical engineering,and the current structure isolation technology has formed a relatively complete system of science.In our country,many years of research and application practice in the field of building isolation and reduction have been made.According to the seismic performance of seismic isolation buildings for many years,the application of seismic isolation technology has a significant effect on the protection of life and property safety.In this paper,the origin and development of seismic isolation are introduced,and the advantages and disadvantages of the traditional seismic method and seismic isolation technology are compared.And the calculation formula of the mechanical properties and the horizontal and vertical stiffness of the lead rubber bearing,and the dynamic analysis model of the multi particle isolation system is derived.Using the methods of theoretical analysis and numerical simulation combined with Kunming a long construction examples,and in high intensity area of high-rise buildings by using the seismic design of the relevant construction examples,research and Analysis on the dynamic characteristics and seismic response of buildings in earthquake and rare earthquake under the action of the study provide a reference for the similar super high earthquake the construction intensity area.The main work done is as follows:1.According to the actual engineering case,the establishment of relevant building model by PKPM software,and the model is introduced into ETABS software by using YJK software,and the correctness of the model calculation and verify the model,calculation and analysis of static elastic and model.2.On the basis of the correctness of the model,according to the actual site conditions in Yunnan Province,this paper studies the seismic isolation mechanism of super long structure and high-rise building in high intensity area.3.Based on the seismic response of high-rise buildings and super long building structures in high seismic intensity area,the seismic isolation design methods and general steps of these two kinds of building structures are studied. |
