Earthquake Response Analysis of Sliding Base Isolation Frame with Equipment of Sliding-Limit under Collision Responses
In order to get over the defects of traditional sliding base isolation structure which the reactions of traditional sliding structure has always increased during the earthquake, and obtain sliding base isolation technology application for the frame structure. Based on the research of U work performances of energy-absorbed element, the whole element model of this new kind of sliding base isolation three storey frame structure with equipment of sliding-limit was established by the SAP2000 software. According to reasonable hysteretic mode, the calculation analysis under collision responses were carried out. The calculation results showed that the rigidity of the new sliding-limit had a great influence on changes of the storey acceleration and displacement after collision. The maximum base sliding displacement of both earthquakes loading was obviously bigger than that of a single earthquake loading. With the other direction loading earthquake increasing, the maximum base sliding displacement of the structure showed signs of increasing first, and then decreasing. Effective theoretical basis of sliding base isolation technology being applied to the frame structure were provided.
