Presentation Forensic analysis of outdoor exposed legacy samples undergoing corrosion propagation Forensic analysis was performed on outdoor samples that showed cracks. One or more rebars were removed from the selected samples. The outdoor samples have been exposed to seawater wet/dry cycles since 1994. In some cases, the three top rebars were removed, in other cases […]

Presentation Meta-learning-based surrogate modeling and system digital twin for life-cycle management of infrastructure systems Life-cycle management (LCM) is an effective tool to balance structural safety and cost. With recent advances in computational power and artificial intelligence, applications of LCM can be extended from single structures and assets to complex networks and systems. This presentation will […]

Presentation Seismic Performance of Corroded Precast Concrete Columns Accelerated Bridge Construction (ABC) results in bridges that are assembled using precast concrete elements built with better quality in significantly shorter time than cast-in-place (CIP) bridges. Despite these advantages, ABC bridges are vulnerable to corrosion, a phenomenon observed in CIP bridges as well. Corrosion adversely affects the […]
