This project belongs to the field of civil engineering. China has the highest total demand and density of high-rise buildings in the world, with over half of its cities located in areas prone to strong earthquakes of magnitude 7 or above. Achieving the control objectives of 'low damage from moderate earthquakes and repairable from major ones' for high-rise buildings has become a significant national need. However, this technology faces three major bottlenecks: 1) There are many components in high-rise structures, resulting in low traditional damping efficiency; 2) Structural disasters are complex, making it difficult to break through the system; 3) Earthquake analysis is intricate, and modeling takes a long time. After ten years of continuous research, supported by projects such as the National Natural Science Foundation of China and the Shanghai Municipal Science and Technology Commission, and through deep integration of industry, academia, research, and application, the project team has made a major breakthrough in efficient seismic damping control technology. Research and development formed the overall technology of 'damping device → energy dissipation system → software integration' for high-rise buildings, with main inventions as follows: 1. Invented wall-type damping devices and a complete set of efficient control technologies, developed high-efficiency damping viscous damper walls and composite material damping wall devices for high-rise buildings, revealed the nonlinear characteristics of viscoelastic materials and the damping mechanism of damping walls, originally proposed the nonlinear model of wall-type damping devices, and established the displacement-based damping control theory and optimization design methods for high-rise buildings. The achievements broke through the bottlenecks of nonlinear damping and composite energy dissipation technologies, realized efficient damping control for high-rise buildings, and the expert appraisal opinion was 'filling the domestic gap'. 2. Invented the energy dissipation and shock absorption cantilever truss system and optimized control technology, developed a new high-rise building variable stiffness energy dissipation and shock absorption cantilever truss system, broke through the traditional disadvantage of excessive internal force fluctuations in the main structure caused by cantilever trusses, established an optimization layout theory for energy dissipation and shock absorption cantilever trusses based on inter-story displacement, and proposed an efficient energy dissipation control design method for the new high-rise building system. The achievements have promoted a leap in the seismic control damping system of high-rise buildings, achieving multi-objective efficient energy dissipation control with 'low damage from moderate earthquakes and repairable after major earthquakes' for high-rise buildings. 3. Developed a software for the mutual conversion between structural analysis diagrams and models of high-rise building damping structures, which is the first to develop a nonlinear analysis software NosaCAD that integrates wall-type damping devices with energy dissipation and shock absorption cantilever truss modules for high-rise buildings. The software is directly based on AutoCAD's powerful graphic functions to establish structural analysis models, enabling rapid model conversion between 10 commonly used domestic and international analysis software such as ABAQUS, ANSYS, PKPM, etc. It also integrates multi-core parallel computing capabilities. The achievement has driven a fundamental transformation in the 'graphical model interchange' of high-rise building finite element models, breaking the technical monopoly of international nonlinear analysis software for high-rise seismic buildings. Based on the above invention, a set of efficient seismic reduction technologies targeting 'low damage from moderate earthquakes and repairable from major earthquakes' in high-rise buildings have been formed. The results have been appraised and novelty checked, both reaching 'international advanced level'. The software has been authorized with 52 national intellectual property rights, including 38 invention patents. 8 utility models, 6 software copyrights; published 2 monographs; published 86 papers, including 28 SCI-indexed and 20 EI-indexed papers; received 2 awards for excellent papers, and been frequently cited and highly evaluated by internationally renowned experts in vibration control such as Professor Christopoulos from Canada and Professor Takewaki from Japan. The project's achievements have been successfully applied in 24 high-rise buildings in 13 cities including Shanghai, Xiamen, Kunming, and Urumqi. The NosaCAD software has been used by more than 100 domestic users; the added value over the past three years is 488 million yuan, creating indirect economic benefits of 482 million yuan and significant social benefits. In particular, the Xiamen International Center is the building with the highest application of viscous damper walls globally, successfully withstanding the test of Typhoon Meranti, a super typhoon level 15. Proves to be of excellent effect. This project supports scientific research on national platforms, leads new directions in the research and design of high-rise building seismic isolation control both domestically and internationally, and has a profound impact on promoting industry technology development.
