大 位 移 摩 擦 摆 底 层 和 多 层 隔 震 韧 性 结 构

The basic performance objectives of structural resilience are that structures can survive very-rare earthquakes and the state of structures and building functions are recoverable. Isolation is a key technology to achieve structural resilience. However，when the response of the isolation layer exceeds its limit，it will causes damage on isolation bearing and the loss of seismic performance. This is the key that constrains the realization of structural resilience. Super-Large Displacement Friction Pendulum Bearings（SLDFPB）whose whole layer acts as a sliding surface and whole superstructure or several frames act as sliding blocks is studied. The new isolated structural system with SLDFPB is constructed through isolation layers located in different positions. A unified analysis model for the structure system is established to explore its damping mechanism and prove its damping performance，so as to achieve structural resilience. The study on structural design method and the evaluation on resilience show seismic damage mitigation and good recovery capacity of the main structure，non-structural members and Super-Large Displacement Translation Friction Pendulum Bearing（SLDTFPB）（bearing and structure layer）. This study provides a new structural system and indicates a key development direction for resilience structures.
