| Abstract |
This study assesses the vulnerability of reinforced concrete buildings, designed according to Korean rural housing standards, to debris flow
using the finite element analysis software ABAQUS. In korea, debris flow vulnerability assessments remain underdeveloped, with traditional
methods often lacking precision. To improve accuracy, this research applies finite element analysis for a more detailed and comprehensive
evaluation. The assessment follows guidelines from the Federal Emergency Management Agency (FEMA) and the National Disaster
Management Research Institute (NDMI), leveraging finite element analysis to enhance reliability. Simulated debris flow conditions provided
strain data, which were analyzed to reflect structural responses. Regression analysis of theses results produced vulnerability curves, illustrating
damage probabilities at varying strain levels. Findings confirm that finite element analysis is a viable and effective tool for evaluating the
structural vulnerability of reinforced concrete buildings to debris flow. This approach offers a significant advancement over conventional
methods, providing deeper insights into structural behavior and informing better risk mitigation strategies. |
