Given the significant impact of seismic disasters, it is particularly important to apply performance-based design methods to building structures for seismic design. This paper first reviews the general methods for building structure design based on performance-based design, followed by a detailed design analysis of building structures using performance-based design methods. Finally, taking a specific building as an engineering example, performance-based design methods are applied to its structural design and analysis. Through the iterative changes in the stress ratio distribution of main components under multiple earthquake levels, it is found that the stress ratio of frame columns increases during the optimization process, with the proportion distributed between 0.6 and 1.0 increasing from 10% to 22%. This indicates that the performance-based design method proposed in this paper plays a positive role in enhancing the seismic performance of building structures.
