Isolation on the Top of Columns of a Building Analysis Based on ETABS
Taking a practical five-story frame-structure with opening floor as background, the finite element analysis software ETABS is used to perform analysis of the first-floor isolation. Time-history analysis for the structures showed that, vibration reduction effect of the superstructure is obvious under 7 degree earthquakes. The substructure (isolated columns) is still in elastic deformation stage under 7 degree rare earthquakes, which proves that isolation technology on the top of columns can improve the seismic behavior of the first-floor weak frame-structure. Meanwhile, mechanical analyses and seismic design of the isolated columns are performed. The results indicated that rational design ensures the structure’s seismic safety.
