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 […]

Presentation Quantifying and Reducing Uncertainty in Resilience Assessment of Transportation Networks Using Dynamic Bayesian Network The Nation’s transportation systems are complex and are some of the highest-valued and largest public assets in the United States. As a result of repeated natural hazards and their significant impact on transportation functionality and socio-economic health of communities, transportation […]

Presentation Evolutionary Characteristics of Microstructural Hydration and Chloride Diffusion in UHPC This webinar presents the evolutionary characteristics of microstructural hydration and chloride migration in ultra-high performance concrete (UHPC). The physicochemical interactions of constituents are simulated in conjunction with a random walk algorithm. The computed responses of the UHPC mixtures at a compressive strength varying from […]
