• Abstract:

  Seismic isolation in-situ connection technology can effectively reduce the dynamic response of the structure and improve its seismic performance and anti-cracking construction effect. In order to analyze the improvement of the seismic performance of steel structure buildings by this technology, a finite element analysis of the seismic performance of steel structure buildings under seismic isolation in place connection technology is proposed. Based on the ETABS finite element software, considering the influence of modular node stiffness domain on the structural stiffness, the foundation seismic isolation design of an office building is carried out to reduce the degree of influence of seismic action on its superstructure and enhance the seismic performance. The modal analysis and time-distance analysis of the object before and after the use of seismic isolation in-situ connection technology show that the first three orders of the self-oscillation period of the object have reached 0.9 s, which is much higher than the characteristic period of the region where the object is located; under the influence of different seismic waves, the east-west and north-south displacements of the seismic isolation layer are 122 and 119 mm, respectively, which proves that seismic isolation in-situ connection technology can significantly reduce the impact of earthquake action on the superstructure of the object. It proves that the seismic isolation in-situ connection technique can significantly reduce the impact of seismic action on the superstructure of the research object, and has better seismic performance.
