IMPLEMENTATION AND VALIDATION OF A HYDRO-MECHANICAL ELASTOPLASTIC CONSTITUTIVE MODEL FOR FULLY COUPLED ANALYSIS OF UNSATURATED SOILS
(2017-05)
Unsaturated soils are commonly encountered in natural soil deposits above the ground water table and in civil infrastructure construction as compacted soils. In earthquake prone areas, problems arise from dynamic loading ...
UNDERSTANDING ULTIMATE SHEAR BEHAVIOR OF PRESTRESSED CONCRETE GIRDER BRIDGES AS A SYSTEM THROUGH EXPERIMENTAL TESTING AND ANALYTICAL METHODS
(2017-07)
A prestressed concrete bridge is a complex system. The interconnectivity of several girders, a deck, and secondary elements such as diaphragms makes their behavior difficult to represent. Additionally, the shear behavior ...
MECHANISTIC INPUT PARAMETERS AND MODEL CALIBRATION FOR DESIGN AND PERFORMANCE EVALUATION OF FLEXIBLE PAVEMENTS IN OKLAHOMA
(2017-12)
The Mechanistic-Empirical Pavement Design Guide (MEPDG) – a product of research and experience involving more than 20 years of traffic, climate and materials data from different regions in the U.S. – has elevated pavement ...
Characterization and Prediction of Flash Flood Severity
(2017-05)
Flash floods, a subset of floods, are a particularly damaging natural hazard worldwide due to their multidisciplinary nature, difficulty in forecasting, and fast response that limits emergency responses. The purpose of ...
