Abstract

The research of the evaluation of seismic performance of base-isolated structure mainly focus on the upperstructure above the isolation equipment at present. However, comparatively little research has been made on the seismic risk analysis of isolation equipment which needs to be perfected further more. The ratio of the horizontal displacement of the isolation equipment and the dimensions of the isolation device (effective diameter of bearing) has been used as the structural demand, and the horizontal displacement limit of the isolation bearing in 2010 Chinese Code for Seismic Design of Buildings (GB50011-2010) has been defined as division standard for reference of the limit states. Then probabilistic seismic demand model (PSDM) for the isolation equipment in the base-isolated structure was initially built, and the exploration of the probability seismic risk analysis of the isolation equipment in base-isolated structure has been performed. At last, a seven-story base-isolated reinforcement concrete (RC) structure which was built in disaster area was studied as an example. This designed model and method was used to evaluate the probability seismic risk of the isolation equipment in the base-isolated structure.
