GFRP Bars in Concrete toward Corrosion-free RC Structures: Bond Behavior, Characterization, and Long-term Durability Prediction
(North Dakota State University, 2016)
Corrosion of steel reinforcements is the leading causes of malfunction or even failures of reinforced concrete (RC) structures nationwide and worldwide for many decades. This arises up to substantial economic burden on ...
Structural Enhancement Utilizing Smart Materials: Experiments and Applications Involving Piezoelectric Actuators and Shape Memory Alloys
(North Dakota State University, 2015)
Smart materials, within the realm of structural engineering, are mainly used as either sensoric mechanisms or as structural damping mechanisms. For the most part, structural enhancement utilizing smart materials is not ...
The Role of Algal Species on Phosphorus Bioavailability in Secondary Wastewater Effluents
(North Dakota State University, 2016)
Phosphorus (P) is a limiting nutrient responsible for the eutrophication of surface waters and marine coasts. Wastewater treatment technologies are being stressed to achieve low P effluents and national effluent P limits ...
Exploring Chemically Treated Fiber Reinforced Pervious Concrete Through Image Based Micromechanical Modeling
(North Dakota State University, 2019)
Pervious concrete has been widely used in parking lots and airport fields. However, past experience has shown durability and strength of the pervious concrete remains a challenge for adopting them in wider applications, ...
Seismic Energy Dissipation, Self-Centering, and Settlement of Rocking Foundations: Analysis of Experimental Data with Comparisons to Numerical Modeling
(North Dakota State University, 2019)
The major objective of this study is to correlate the rocking foundation performance parameters with their capacity parameters and earthquake demand parameters using the results obtained from 142 centrifuge and shaking ...
Traffic Monitoring System Using In-Pavement Fiber Bragg Grating Sensors
(North Dakota State University, 2019)
Recently, adding more lanes becomes less and less feasible, which is no longer an applicable solution for the traffic congestion problem due to the increment of vehicles. Using the existing infrastructure more efficiently ...
Modeling of Temperature Impacts on Fixed Film Microbial Growth and Nitrification Kinetics
(North Dakota State University, 2014)
Monod-type kinetic models, used in simulating microbial growth in biological treatment systems, suggest significant decreases of substrate utilization at lower temperatures. However, it is documented that performance of ...
Dispersion Effectiveness of Carbon Nanotube Additives in Self-sensing Cementitious Materials for Structural Health Monitoring
(North Dakota State University, 2016)
The use of self-sensing materials such as piezo-resistive cementitious materials modified by carbon nanotube (CNTs) additives may be able to achieve a potential real time structural health monitoring in structures. However, ...
Safety Effectiveness and Safety-Based Volume Warrants of Right-Turn Lanes at Unsignalized Intersections and Driveways on Two-Lane Roadways
(North Dakota State University, 2012)
Disagreements regarding to what degree right-turn lanes improve or worsen the safety of intersections and driveways provided the motivation and the need for this study. The objectives of this study were to: a) carry out ...
Clay Fluid Interactions in Montmorillonite Swelling Clays: A Molecular Dynamics and Experimental Study
(North Dakota State University, 2012)
Swelling clays cause tremendous amounts of damage to infrastructure. For the effective prevention of detrimental effects of these clays, and to optimize the beneficial properties for industrial applications it is necessary ...
