Seismic Response Analysis of a New Staggered Story Isolated Structure Under Three-Dimensional Long-Period Earthquakes
https://orcid.org/https://orcid.org/0000-0003-3795-1814
The new staggered story isolated structure (NSSIS) is a new structure developed from the base isolated structure and mid-story isolated structure. In this paper, a finite element model of an NSSIS was established and the dynamic response of the NSSIS under three-dimensional (3D) long-period earthquake waves was analyzed. As the tensile and compressive stress of the isolated bearings exceeded the limit value under the 3D long-period earthquake waves, the 3D isolated bearings were introduced and compared with the traditional horizontal isolated bearings. The results show that the earthquake response of the NSSIS under long-period earthquake waves were larger than ordinary earthquake wave. The earthquake response of structure under 3D earthquake waves was larger than that under one-dimensional (1D) and two-dimensional (2D) earthquake waves. After setting 3D isolated bearings, the earthquake response of the structure was reduced, the shock absorption performance of the structure was improved, the compressive and tensile stress of isolated bearings met the requirements. It can provide a reference for the study of the NSSIS under 3D long-period earthquake waves.
