摘要

The seismic resilience of RC structures is critical in earthquake-prone regions. Utilizing advanced numerical modeling and dynamic analysis, the study compares the performance of the bracing systems under a range of seismic loads. The impact of the different bracing methods on seismic parameters such as overturning moment, maximum story drift, story displacement, and story shear was examined using the response spectrum method. The preferred usage of this system is by means of the shear walls which assist in consolidating the structure. Due to the high cost of the shear wall installation, the analysis of the residential building with steel bracings of varying combinations and the resultant displacement of the frame model was carried out. The findings indicate that combining different bracing configurations can significantly improve the overall seismic response, reducing inter-story drifts and mitigating potential structural failures. This research provides valuable insights for structural engineers and contributes to developing more resilient RC frame buildings capable of withstanding severe seismic events.
