Research Goal

The ultimate research goal of SAFE C.I.T.I. (Community and InTegrated Infrastructure) Research Group is to identify Resilient Modern Society against Natural and Man-made Hazards including NaTech (Natural Hazard Triggered Technological) hazards by protecting aging critical infrastructure systems including coastal and offshore structures vulnerable to weather-related disasters due to climate change

 Research Interests                                                                                                 

- Extreme Multi-Hazards (Earthquakes, Storms, Floods, Blasts, Impacts, Fires, etc.)
- Multi-Scale Nonlinear Transient Structural Performance Evaluation
- Probabilistic Risk and Resilience Modeling for Structures and Complex Systems
- Effects of Structure Aging and Climate Change
- Machine Learning and Big Data Analytics Application to Structural Engineerin

Structures and Complex Systems include (not limited to) Buildings, Hospitals, Energy Infrastructure Systems, Coastal and Offshore Structures, Infrastructure System Network, etc.

 Civil Infrastructure Systems and Community Resilience Research                 

Module I: Multi-Hazard Research
The main research tasks of Module I are to identify, characterize, and assess critical hazards to inform the frequencies and intensities at a specific site, and the correlations between hazards.

Category 1 - Natural Hazards
                      A. Earthquakes

                      B. Tsunamis                      
                      D. Stroms
                      E. Future items
Category 2 - Technological Hazards
                      A. Explosions
                      B. Fires
                      C. Impact Loads
                      D. Collisions
                      E. Future items

Module II: Multi-Scale Failure Research 
The main research tasks of Module II are to perform modeling and simulations for structural behavior at the system level based on material responses and to quantify the risks to the community based on the system level structural damage.

Category 1. Constitutive/Component Level
                      A. Structural components
                      B. Pipelines
                      C. Future items
Category 2. System Level
                      A. Structural systems
                      B. Lifeline systems
                      C. Transportation systems
                      D. Future items
Category 3. Community Level; (coastal, waterfront, urban, rural ... )
                      A. Economic impact
                      B. Human safety
                      C. Environmental impact
