Abstract

Building information modeling (BIM) methodology has been widely adopted for engineering projects, such as buildings, bridges, pipelines, and roads. However, BIM has yet to be fully utilized for risk assessment of critical facilities with multiple infrastructure systems. In this study, a BIM-based seismic risk assessment framework is proposed. The digital BIM model contains component-level information on the building's structural and non-structural elements, and this digital data allows the execution of component-based analysis of seismic risk. The seismic vulnerability of the components can be evaluated according to fragility curves, where each model element is attributed its corresponding fragility parameters. Each model element is assigned the median and standard deviation capacity for each damage state. Subsequently, various seismic scenarios can be simulated. The results of the simulations allow quick assessment of the seismic performance of the infrastructure and identifying the most vulnerable components. The proposed framework provides a valuable tool for engineers and decision-makers in assessing the seismic risk of infrastructures and implementing necessary measures to increase their resilience. Our preliminary work shows that BIM can provide valuable information and visualization tools for seismic risk assessment and can help improve the efficiency of the assessment process.
