ANALYSIS AND DESIGN OF BUILDING ISOLATION UNDER A CONVEX TERRAIN IN HIGH INTENSITY AREA
Taking a primary and secondary school teaching building project in Lushui City,Yunnan Province as the research object,YJK and ETABS structural analysis software were used to analyze and design the seismic isolation time history of the slope building located in the local prominent terrain in the high-intensity area.Through comparison and analysis with the calculation results of YJK non-isolation model,the isolation technology can significantly prolong the period of the structure itself,reduce the interstory shear force and the bottom shear force,effectively weaken the horizontal earthquake effect,and have a good damping control effect on this type of building.Taking practical engineering as an example,this study introduced the steps and processes of isolation design,reasonably considered the impact of local outburst terrain on the earthquake,carried out time-history analysis and verification calculation of the isolation building under fortification and rare earthquakes,and provided references for the design,research and application of isolation technology under local outburst terrain in high-intensity areas.
