## TL;DR

This paper reviews how structural stiffness in concrete buildings affects their vibration periods, showing that stiffer elements reduce these periods significantly, improving seismic safety.

## Contribution

The study systematically reviews and quantifies the impact of structural stiffness on vibration periods, offering new insights for seismic-resistant building design.

## Key findings

- Increased stiffness in structural elements can reduce vibration periods by 20–50%.
- Low-rise buildings can see a 53–70% reduction in fundamental period with stiffer elements.
- Stiffer designs improve seismic resistance and reduce damage risk in concrete buildings.

## Abstract

Research on the relationship between structural characteristics and vibration periods in concrete buildings is crucial to ensure the safety and efficiency of these structures, especially in earthquake-prone areas. This article aims to analyze and compare the impact of structural stiffness of different elements, such as beams, columns and shear walls, on vibration periods, through a systematic review of existing models and formulas in the literature, identifying their applications and limitations. The methodology used consists of a systematic review that integrates recent and relevant studies, providing a solid basis for analysis. The results indicate that an increase in the stiffness of structural elements can reduce vibration periods by 20–50%, implying a faster response to external forces. Even in low-rise buildings, the fundamental period can be reduced by 53% to 70%. These findings are significant for the design and construction of concrete buildings, as they suggest that incorporating rigid structural elements can improve seismic resistance and reduce the risk of damage. In addition, the research contributes to the field of structural dynamics by highlighting the need to integrate different methods of analysis and evaluation. It is recommended that engineers and architects adopt innovative approaches, such as the use of emerging technologies and monitoring methods, to improve damage detection and optimize structural design. Finally, it identifies areas where more research is required, suggesting that future studies should explore the interaction between structural characteristics and environmental conditions for a more complete understanding of the vibrational behavior of buildings.
