Progressive Collapse and Robustness Analysis of Multi-Story Reinforced Concrete Structures

OpenAlex İngilizce

Progressive collapse is a critical structural phenomenon where local damage triggers a chain reaction and potentially leads to disproportionate failure of the entire system. In this study, the progressive collapse behavior of multi-story reinforced concrete (RC) structures is investigated using numerical analysis methods. This situation poses a serious danger, especially for high-risk types of structures. In the study, the effect on the collapse tendency is evaluated by considering different structural models. Numerical analyses are performed using a nonlinear finite element method. This study offers a general exploration of the progressive collapse behavior of multi-story RC frames, focusing on robustness evaluation under various structural scenarios. The aim of this study is to improve the understanding of structural responses and to support the development of safer, more durable design strategies.
