Professor Ross Corotis is coordinator of the Structural Engineering and Structural Mechanics area, and a founding member of the Civil Systems area. He and his group conduct research on the modeling of natural hazard effects on structures and communities. This spans from structural system reliability to policy and management approaches for evaluating risk in the built environment. They have expanded reliability approaches to estimate seismic loss and prioritize mitigation, and created models for risk communication based on risk perception principles. They have also developed generalized methods of uncertainty to evaluate risk and resilience. Visit his CEAE profile page here.
1. Use of generalized information theory to incorporate linguistic variables in post-disaster building inspection/ratings.
Building condition assessments following a disaster depend on assignment to broad categories and require subjective judgement. Theories based on belief/plausibility theory and fuzzy classification are well suited to these types of uncertainties and offer powerful alternatives to probabilistic methods.
2. Merging uncertainties from expert opinions, linguistic descriptors and social variables in a comprehensive framework for community infrastructure resilience assessment.
Consideration of community resilience should include metrics related to physical building/infrastructure performance, direct/indirect economic impacts, environmental consequences and social well-being. Each of these disparate categories incorporates different types and degrees of ambiguity. In order to ensure that all effects are assimilated appropriately, it is necessary to develop a comprehensive framework that admits these inherently incompatible uncertainty factors.
3. Extension of Performance-based engineering approaches to building code development to incorporate consideration of resiliency following a disaster.
Building codes traditionally have been based solely on life safety considerations related to individual structures. General comments regarding progressive collapse and disproportionate damage are sometimes included. A conceptually novel approach is to incorporate considerations of damage repair, functionality restoration, and building usage in the context of community-wide assets and services.
Professor Corotis collaborates with Professors Liel and Porter on community disaster evaluation, risk, communication, and rebuilding/resilience processes. He also shares interests with Professors Javernick-Will and Dashti on disaster strategies.
