Forterra Resilience & Sustainability Webinar

Presentation Sustainability is key to building a brighter future for our families and our communities. What we do today affects tomorrow. This presentation covers the three pillars of sustainability, and provides principles of resilience to support our efforts to build a sustainable infrastructure. In terms of environmental sustainability, this means being conscious of our world […]

Post-Earthquake Assessment of Bridge Columns Using AI Enabled Computer Vision

Presentation Post-Earthquake Assessment of Bridge Columns Using AI Enabled Computer Vision Modern seismic design codes ensure a large displacement capacity and prevent total collapse for bridges.  However, this performance objective is usually attained at the cost of damage to target ductile members.  For reinforced concrete (RC) bridges, the columns are usually the main source of […]

Carbon-Fiber Tape Based Electrical Deicing System: Experiments, Field Performance and Application Issues

Presentation Carbon-Fiber Tape Based Electrical Deicing System: Experiments, Field Performance and Application Issues In cold regions, snow and ice cause serious safety problems to the transportation system.  Southcentral Alaska, particularly, Anchorage, is susceptible to a large number of icing events due to frequent freeze and thaw cycles in the winter season.  Icing on pavement and […]

Recent Advances in Measuring Volume of Soil Specimen in Triaxial Testing

Presentation Recent Advances in Measuring Volume of Soil Specimen in Triaxial Testing Triaxial tests have been widely used for measuring the stress-strain behavior of both saturated and unsaturated soils. Volume/displacement measurement is an indispensable component of the triaxial testing. This paper provides a state-of-the-art review on the existing methods to measure volume change and/or displacement […]

Rock Failure Process Analysis

Presentation Rock Failure Process Analysis A major difficulty in studying the fracture mechanisms for rock subjected to various loads is the fact that rock is a natural, composite material which is Discontinuous, Inhomogeneous, Anisotropic and Not Elastic (DIANE). It is not possible to analytically examine and evaluate the mechanical behavior of a DIANE rock exhibiting […]

Long-term Bond Characteristics of the Interface Between Substrate and Shotcrete Overlay

Presentation Long-term Bond Characteristics of the Interface Between Substrate and Shotcrete Overlay Shotcrete is becoming popular for vertical and overhead applications where conventional formwork and repairs are difficult and costly. However, the substrate and the shotcrete overlay interface can be vulnerable, and the bond properties in this region are not well understood. Furthermore, the interface […]

Decryption of Concrete Durability Deterioration Mechanisms Using Concrete Petrography and Image Analysis

Webinar

Presentation Decryption of Concrete Durability Deterioration Mechanisms Using Concrete Petrography and Image Analysis While good workability and mechanical performance are critical for the construction of transportation infrastructure, the stakeholders also seek durable concrete that can last a desired service life without significant deterioration. Concrete durability comes in different forms of complex processes that commonly involve […]

Developing Enhanced Performance Curves of ITD Asphalt Pavements by Mining the Historical Data

Presentation Developing Enhanced Performance Curves of ITD Asphalt Pavements by Mining the Historical Data This presentation introduces work of a recently finished project aiming to develop reliable and realistic and enhanced performance curves for Idaho Transportation Department (ITD) asphalt pavements by mining the historical data. To this end, the project reviewed currently applied predictive models […]

Quantifying and Reducing Uncertainty in Resilience Assessment of Transportation Networks Using Dynamic Bayesian Network

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 […]

Seismic Performance of Corroded Precast Concrete Columns

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 […]
