RISK ASSESSMENT AND MANAGEMENT OF STRUCTURAL AND INFRASTRUCTURE SYSTEMS LABORATORY

About RAMSIS Lab

Critical infrastructure systems (CIs) are becoming increasingly vulnerable to system-wide failure primarily due to aging, natural and manmade hazards, climate change, and increased interdependencies, among other factors. Quantitative and qualitative assessment of the associated risk is crucial in pre-event planning and post-event response.
Risk Assessment and Management of Structural and Infrastructure Systems (RAMSIS) lab develops and applies probabilistic risk analysis frameworks to various CIs and their components to assess their reliability and resilience against perturbations. This can provide valuable knowledge about a number of principal effects such as traffic disruption, impact on the regional and global economy, and resilience of systems and communities.
RAMSIS Lab research focuses on:
- Numerical modeling and fragility assessment of complex systems, such as seaports, bridges, and physical assets of power grids with consideration of soil-foundation-structure interactions and liquefaction effects
- Probabilistic modeling of deterioration processes of reinforced and prestressed concrete structures coupled with FE simulations
- Optimal maintenance policies for large aging infrastructure assets using stochastic methods
- Advanced protection of critical geo-structural systems against extreme hazards such as earthquakes and strong winds using passive, active, and semi-active control strategies based on stochastic methods
- Reliability and resilience assessment of geo-structural systems and critical infrastructures against natural and manmade hazards
The above research objectives are accomplished by bridging stochastic methods and Finite Element models to realistically model the system of interest and capture various sources of uncertainties.

Shafieezadeh bio
Dr. Shafieezadeh is the Lichtenstein Associate Professor in the Department of Civil, Environmental & Geodetic Engineering at The Ohio State University. He directs Risk Assessment and Management of Structural and Infrastructure Systems (RAMSIS) lab. The research interests of his lab include
- advancing uncertainty quantification methods focusing on applications related to reliability, resilience, and life-cycle performance of structural and infrastructure systems,
- decision making in stochastic environments, including topics such as planning and sequential decision making, value of information analysis, and deep as well as safe reinforcement learning, and
- physics-based, data-informed computational modeling of the built environment, specifically focusing on applications related to aging processes and the compounding effects of aging and extreme hazards on infrastructure components and systems.
These advancements have been applied at RAMSIS lab to a wide range of structures and infrastructure systems from buildings, bridges, electric utility structures, wharves, underground pipes, and levees to the power grid, seaports, pipelines, bridge networks, and flood defense systems.
Dr. Shafieezadeh's research has tackled both acute stresses from climatic and geologic hazards as well as chronic stresses of aging and deterioration. The research at RAMSIS lab has been supported by a large, diverse group of federal and state agencies as well as the industry and international entities.
