Analysis and Application of Isolation Layer of a School in Highly Fortified Area

Abstract A school complex building is located in an area with a seismic fortification of 8 degrees, with six floors above the ground and two floors below the ground, and has a frame structure. Using YJK calculation program and elastic time history analysis method, the calculation model is established. Through the comparison and verification of the isolated model with the isolated unit and the non-isolated model, the isolation scheme is determined, and the isolation scheme is determined through analysis and research. The isolation layer is arranged on the top of the basement column, and an isolation support is arranged on the bottom surface of each column of the isolation layer to separate the upper structure from the top of the basement column or the top of the beam so as to isolate the seismic energy and reduce the seismic action of the upper structure.
