Structural Preservation
Research in structural assessment and preservation at Portland State University centers on extending the life, safety, and sustainability of existing infrastructure. With much of the nation’s bridges, buildings, and transportation systems aging beyond their original design life, PSU engineers are developing advanced tools to evaluate structural condition, predict deterioration, and guide cost-effective preservation strategies.
A major emphasis is on non-destructive evaluation (NDE) and structural health monitoring (SHM)—technologies that allow engineers to assess damage and material degradation without intrusive testing. Research led in part by faculty such as Thomas Schumacher explores acoustic sensing, ultrasonic techniques, and vision-based monitoring systems to detect cracking, corrosion, and fatigue in concrete and steel structures.
Complementing this work, David Yang's research centers around probabilistic life-cycle modeling and risk-informed decision frameworks integrates uncertainty, climate stressors, and long-term deterioration into predictive models. This research allows agencies to manage their assets smarter, giving them tools to determine when preservation, retrofit, or replacement investments will deliver the greatest benefit.
Together, these efforts strengthen the resilience and longevity of critical infrastructure by reducing lifecycle costs and creating more sustainable infrastructure systems, all while supporting data-driven policy and investment decisions at local, state, and national levels.
