Evaluating the Effects of Climate Change on Spring Load Restrictions across Ontario, Canada
Publisher: American Society of Civil Engineers
Abstract: Recently, numerous studies have highlighted that the climate worldwide is changing rapidly due to increased greenhouse gas (GHG) emissions. The average ambient temperatures across Canada are rising approximately twice as ...
Effect of Climate Change on Thermal Loads in Concrete Box Girders
Publisher: American Society of Civil Engineers
Abstract: Throughout their service life, bridges are exposed to ambient actions and environmental influences such as wind, thermal, and snow loads. Bridge design for environmental actions is currently based on observed, historical ...
Flux-Based Alternative Formulation for Variably Saturated Subsurface Flow
Publisher: American Society of Civil Engineers
Abstract: Finite-element and finite-difference solutions to different forms of the Richards equation can exhibit stability problems as well as mass balance errors. These problems are more pronounced for sharp wetting fronts in soils ...
Numerical Study on the Effect of Climate Parameters on the Extreme Thermal Gradients in Concrete Box Girders
Publisher: ASCE
Abstract: Bridge codes tend to provide general guidance on the thermal gradients acting on bridge decks based on data from historical extreme events that have occurred within a country, without considering the location of the bridge ...
Temperature Effect on the Thermal Expansion Coefficient of Concrete
Publisher: American Society of Civil Engineers
Abstract: The coefficient of thermal expansion (CTE) is typically assumed to be constant in RC bridge design. In fact, under freezing temperatures, the CTE of concrete exhibits hysteretic nonlinear response, which, however, is rarely ...
