Study on Seismic Performance of a Super High-rise Building Based on the Rare Earthquake

With the development of the architecture science, the super high-rise building in highly seismic region is growing, and its height is also increasing. Designing new kind of super-rise structure system, and checking its safety and reliability are the tasks for structure engineers to challenging. This paper assumes that in the highly seismic region, takes giant framework super-tall structures as example, and tests the deformation, stress and damage conditions of the structure under seismic affection. This structure system is consisted of mega steel frame and steel plate shear wall core tube, by setting up outside cylinder conversation truss and huge brace, the steel amount is decreasing effectively, in the condition of ensuring the overall stiffness to resist lateral force. The analysis result shows: In the effect of rare earthquake, the outside cylinder frame forms the hinge mechanism gradually, which play a good effect of energy consumption, Shear wall concrete damage seriously. In the condition of considering the elastoplastic material, the maximum interlayer displacement angle of the structure satisfies the 1/100 limitation requirement, the structure meets the "don't collapse under the rare earthquake" fortification criterion.
