Abstract
With the accelerating urbanization process, the number of high-rise buildings is increasing, making the optimization design of their seismic performance a critical issue for ensuring structural safety and protecting human lives and property. This study aims to enhance the seismic capacity of high-rise buildings by integrating finite element analysis, shake table tests, and intelligent optimization algorithms to systematically investigate the response characteristics and failure mechanisms of structural systems under seismic loads. By incorporating machine learning-based predictive models, an efficient evaluation of structural damage states under complex earthquake loads was achieved. A novel design method combining topology optimization with material distribution adjustment was proposed. The results indicate that this method can significantly reduce stress concentration in key structural areas, improve overall seismic performance, and decrease material consumption by approximately 15%. Additionally, an integrated design tool was developed to provide technical support for engineering practice. This research not only enriches the theoretical fr amework of seismic design for high-rise buildings but also offers innovative and practical solutions for real-world applications, demonstrating significant academic value and engineering implications.
