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 ...
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 ...
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, ...
Development of Passenger Car Equivalency Values for Heavy Vehicles for Protected Left-Turn Movements at Signalized Intersections
(North Dakota State University, 2016)
The Highway Capacity Manual (HCM) provides methods to account for the impact of heavy vehicles in the operational assessment and design of signalized intersections. However, the overall impact of heavy vehicles on the ...
An Integrated System for Road Condition and Weigh-in-Motion Measurements using In-Pavement Strain Sensors
(North Dakota State University, 2016)
The United States has the world’s largest road network with over 4.1 million miles of roads supporting more than 260 million of registered automobiles including around 11 million of heavy trucks. Such a large road network ...
In-Pavement Fiber Bragg Grating Sensors for Weight-In-Motion Measurements
(North Dakota State University, 2016)
Estimation a traffic over the design period is one of the critical factors in pavement design. Weight-in-motion (WIM) sensors have become popular for weight measurements. A three-dimension glass fiber-reinforced polymer ...
Dynamic Interaction of Vehicle and Bridge Subjected to Prestress Force Loss and Foundation Settlement
(North Dakota State University, 2016)
Plenty of bridges in U.S. are suffering from prestress force loss and foundation settlements. The loss of prestress force in bridge load-carrying members such as girders may lead to the malfunction and even failure of the ...
Parametric Cost Estimating and Risk Analysis of Transportation Tunneling Projects
(North Dakota State University, 2016)
Due to the increased scrutiny of construction costs for infrastructure projects by the
public and legislators, it is becoming increasing important for project developers to prepare
accurate conceptual cost estimates for ...
Spatial Scale Dependence of Drought Characteristics and Impact of Drought on Agriculture and Groundwater
(North Dakota State University, 2016)
Drought is a water related natural hazard. It is difficult to characterize drought because of its diffused nature and spatiotemporal variability. However, understanding the variability of drought characteristics such as ...
Holistic Risk Assessment of Surface Water Contamination by Naturally Occurring Radioactive Material in Oil Produced Water from the Bakken Shale
(North Dakota State University, 2016)
The risks to the environment and human health due to hydraulic fracturing (HF) in onshore unconventional oil and gas (O&G) development have been studied in the past but results are inconclusive. A common shortcoming in ...
