Investigation of Extreme Environmental Conditions and Design Thermal Gradients during Construction for Prestressed Concrete Bridge Girders
Publisher: American Society of Civil Engineers
Abstract: Current AASHTO specifications provide engineers with a temperature gradient across the depth of the cross section to predict the vertical thermal behavior of bridges. This gradient is based on one-dimensional heat flow and ...
Application of Probabilistic Neural Networks for Prediction of Concrete Strength
Publisher: American Society of Civil Engineers
Abstract: The compressive strength of concrete is a commonly used criterion in producing concrete. However, the tests on the compressive strength are complicated and time consuming. More importantly, it is too late to make improvements ...
