Based on the research findings of the former project about the mega-frame structuer, the multifunction vibration-absorption mega-frame structuer(MVMS) is selected as the research object. Using the method of numerical simulation and the technique of shaking table test,the research on the characteristic of the energy response and the collapse resistant capacity of MVMS will be conducted. The study on the evolution process of the structural damage of MVMS based on the results of energy analysis will be carried out to reveal the damage and collapse mechanism. In this project,the organic combination of ground motion input based on intensity index, performance-based seismic design of the MVMS, three dimensional analysis of inelastic dynamic responses of multi-degree-of-freedom system, the law of structural seismic energy, integrality performance and collapse resistant capacity of the super high-rise structure, and the process of failure based on seismic damage index can reflect the spirit of innovation. The research will promote the innovation of seismic design theory and engineering application, and the research on the dynamic disaster of super high-rise structure will be advanced.
