This project is a research achievement in the field of civil engineering, specifically focusing on architectural structures. The team has concentrated on the significant needs of China's large-scale urbanization process and has relied on projects such as the National Natural Science Foundation of China's Innovative Research Group Project and the 'Dynamic Disaster of Major Projects' major research plan to achieve a series of high-level research results with independent intellectual property rights. These achievements have been successfully applied to the disaster optimization design of a number of representative projects, achieving good economic and social benefits. The main technical innovations are as follows: (1) Innovation in material constitutive models: Concrete elastoplastic damage constitutive relationship and efficient numerical realization technology. A concrete elastoplastic stochastic damage physical model has been established. Scientific quantification of the tensile stiffening effect, compressive hoop reinforcement constraint effect, and biaxial tension-compression softening effect of reinforced concrete composite materials has been achieved. The elastoplastic damage theory of reinforced concrete composite materials has been systematically developed, overcoming the empirical dependence of classical concrete constitutive relations and realizing a unified reflection of static and dynamic nonlinear behavior of concrete. This has laid a theoretical foundation for the detailed analysis of complex structures. The research results have been incorporated into China's current 'Code for Design of Concrete Structures', filling the gap in China's research and standardization of concrete damage constitutive relations. (2) Innovation in structural analysis methods: Large-scale complex building structure dynamic disaster simulation analysis technology and platform. An implicit gradient fiber beam-column element based on force method has been proposed, a refined flat plate shell element has been developed, a series of precise and robust numerical algorithms have been developed, and rapid modeling, The large-scale nonlinear analysis software system ADARCS, which includes multi-scale failure criteria and efficient solution algorithms, has established a sophisticated analysis technology platform for complex building structures. It achieves the analysis of the entire process from material damage to component failure, and then to partial or complete structural collapse of complex buildings. This has laid a technical foundation for the detailed analysis of large and complex building structures. (3) Structural Performance Regulation Innovation: Disaster-resistant optimization design and performance regulation technology based on overall structural reliability. It proposes a structure disaster-resistant optimization design technology that considers overall reliability and multiple constraint indicators, develops damper optimization layout schemes based on grid shear velocity, realizes integrated optimization design and overall performance regulation for complex structures with multi-objective performance as well as the combined action of the main structure — auxiliary devices, and has been successfully applied in projects such as Shanghai Tower, Chengdu Greenland Center, and Guangzhou Tower. Complex architectural structures such as Wuhan Greenland Center have significantly improved the cost-effectiveness and urban resilience to disasters while ensuring structural safety, with very significant social and economic benefits. Based on the aforementioned innovative research results, the project team participated in compiling 1 national standard, published 1 Chinese monograph; published 114 journal papers, including 32 SCI-indexed and 46 EI-indexed articles; won 1 first prize of Huaxia Construction Science and Technology Award and 1 award from an international top academic journal; obtained 4 invention patents, 1 utility model patent, and 5 software copyright registrations. During the research period of the project, the main contributors were approved for 1 National Natural Science Foundation Committee Innovation Research Group, 1 Young Scientist Fund, 1 Outstanding Youth Science Fund, and 2 nominations for the National Excellent Doctoral Dissertation Award. The direct economic benefits generated by the project's research totaled 470 million yuan, saving over 460 million yuan in costs.
