Abstract

Based on an engineering case, this paper systematically investigates the influence of structural system selection, key member design, and seismic strengthening technologies on seismic performance by adopting various methods, including elastic analysis and elastoplastic time-history analysis. The results show that reasonable selection of structural systems such as frame-core tube systems, optimization of shear wall and frame column design, and application of targeted strengthening measures can effectively improve the lateral and torsional stiffness of structures and control inter-story drift ratios. This study achieves the preset seismic performance objectives under different seismic levels, provides theoretical and practical reference for seismic design of super high-rise buildings, and is of great significance for addressing seismic design challenges under complex working conditions.
