A COMPREHENSIVE FRAMEWORK TO MITIGATE SURFICIAL SLOPE FAILURES
(2021-05-09)Each year, numerous highway and dam slopes that are built with high plasticity clays experience shallow slope failures. Besides the high maintenance and repair costs, these failures negatively impact the public life by ... -
A COMPREHENSIVE RESILIENCE FRAMEWORK FOR THE SEISMIC EVALUATION OF HYDRAULIC FILL DAMS IN NORTH TEXAS
Hydraulic filling is a construction procedure that was used for earthen structures during the mid-1800s to the early 1900s; however, dams and levees that were constructed by implementing this technique had a significant ... -
A COMPREHENSIVE SEISMIC RESPONSE AND SLOPE STABILITY ANALYSIS FRAMEWORK FOR EVALUATING THE STABILITY OF HYDRAULIC-FILL DAMS
(2018-08-13)The stability and serviceability of earthen embankment structures such as dams and levees are extremely crucial to avoid the catastrophic consequences of the failure of these structures. Such man-made geo-structures are ... -
A Critical State Approach to the Mechanical Behavior of Early-Age Cemented Paste Backfill
(2019-12-16)Low plasticity to non-plastic mine tailings are typically transported to a storage area through pipelines in form of slurry or thickened tailings. The main concern with such tailings deposits is the possibility of liquefaction ... -
A DECISION SUPPORT SYSTEM FOR SUCCESS OF POST-HURRICANE RECONSTRUCTION OF TRANSPORTATION INFRASTRUCTURES
(2020-09-03)In the aftermath of hurricanes, when reliable transportation systems are vital, the chaotic and complex environment creates multiple uncertainties and risks in the reconstruction of transportation infrastructures. Damaged ... -
A DECISION SUPPORT SYSTEM FOR TRAFFIC DIVERSION AROUND CONSTRUCTION CLOSURES
(2016-08-12)As highway infrastructure ages and road congestion increases, roads need to be expanded and reconstructed. It results in creating many construction sites and work zones on highways, which leads to an unavoidable interruption ... -
A Decision Support System Tool for Dynamic Pricing of Managed Lanes
(2016-09-16)Congestion pricing and managed lanes (ML) have been recently gaining interest around the country as a congestion management tool and as a means of revenue generation for facility maintenance and expansion as well repayment ... -
A NEW APPROACH FOR PERFORMANCE EVALUATION OF BRIDGE INFRASTRUCTURE USING TERRESTRIAL LIDAR AND ADVANCED MATHEMATICAL MODELING
(2018-08-20)High plastic expansive clays when subjected to different climatic conditions undergo large ground movements causing distress to infrastructures including bridges, pavements, buildings, retaining structures, and others. ... -
A NEW DESIGN METHODOLOGY OF REINFORCED CONCRETE SQUAT SHEAR WALLS FOR DUCTILE SEISMIC BEHAVIOR AND PREDICTABLE SHEAR STRENGTH
(2019-08-09)Reinforced concrete (RC) squat walls (with a height-to-length ratio of 2.0 or less) have high strength and stiffness which makes them a popular seismic force-resistant system for buildings and nuclear power plants. However, ... -
A NEW GEOTHERMAL BRIDGE DE-ICING SYSTEM WITH ATTACHED HYDRONIC HEATING LOOPS: FIELD TESTS, NUMERICAL MODELING, AND ECONOMIC ASSESSMENT
(2021-08-10)Each year, ice and snow adversely impact U.S. transportation infrastructure during the cold season, causing an extensive impact on the U.S. economy. Bridges are key elements in the transportation network and the most ... -
A Parametric Study Of The Effects Of ɛ And 𝑘̅ On The Poisson Boltzmann Equation For One And Two Spherical Particles Using A Boundary Integral Equation Method
Many biomolecules, such as DNA, exhibit properties that are dependent on their electrostatic interaction with an electrolytic solution. Both explicit atomistic and implicit continuum models have been developed to solve the ... -
