Abstract:The whole process of base isolation analysis of multi-tower high-rise structure in Pingliang City Museum was introduced. Several parameters of isolator bearings were introduced in detail, including parameter setting, structural form selection principle, the value of the horizontal damping coefficient, the design internal force of the isolated pier, and seismic performance evaluation. The issues of the selection of seismic waves and bearing damping parameters were focused on. Combining with the acceleration response of the structural floor under the rare earthquake, seismic protection suggestions were provided for anti-slip and anti-overturning of cultural relics in the museum. The reliability of the structure was verified through the elastic-plastic analysis under the rare earthquake, which provided a reference for the design of similar isolation structures.
Keywords:high-rise multi-tower frame structure; base isolation; seismic protection for culture relic; performance evaluation
