摘要：
The failure mechanism and damage distribution of the mega-tall building benchmark model was investigated by dynamic elasto-plastic analysis. The benchmark model with the height of 606.1 m used mega frame-core with outrigger steel-concrete composite structure system. An elasto-plastic model was established using PERFORM-3D software. The analysis was conducted in different seismic levels, i.e. frequent earthquakes, basic earthquakes, rare earthquakes, and extremely strong earthquakes to investigate the dynamic responses and failure process. The results show that the structure has a good seismic resistance. The structure will not collapse in rare earthquake of intensity 9. The structural damages concentrate on the stories close to the strengthened stories in zones 4-8, and the damage spreads to the middle of these zones as the seismic intensity increases. The concept of multiple seismic fortification lines has been well implemented. Different structural components yield respectively under different seismic intensities. © 2016, Editorial Office of Journal of Building Structures. All right reserved.
