Abstract: Structural software MIDAS was used to perform Pushover analysis on a super high-rise building. Key parameters of performance-based design and analysis model were discussed. Static elasto-plastic characteristics of the building, as well as the plastic lunge development pattem of the structure, under rare earthquake were obtained through Pushover analysis. Thus provide basis for design optimization and strengthening weak locations of the building.
Keywords: MIDAS; super high-rise building; Pushover analysis; plastic hinge development
