Assessment of Multi-year Hydrologic Performance of Bioretention Facility using Real-Time Sensors

Creator:: Alyousef, Hashim A.
Abstract:: Bioretention facilities are emerging as a popular way to deal with stormwater runoff in urban environments and address its concerns. Real-time sensors installed in bioretention facilities aid in understanding the performance and feasibility of such facilities over time. A bioretention facility in Corvallis, Oregon was monitored for a study period...

Long Wave Amplification in a Coral-Reef Lagoon

Creator:: Bheeroo, Vivek Anand
Abstract:: A series of laboratory experiments were conducted to study the wave field in the inner lagoon excited by ‘long’ incident waves. Three cases were considered: Cases A, B and C presenting incident waves of wavelength with factors of 1, 2 and 2.5 times the width of the reef respectively. The...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

Full Text:: Chlorides can also significantly influence the corrosion at RC systems. Chlorides ( C l  ) can be

Non-destructive determination of yield stress for in-situ gusset plates

Creator:: Pflaum, Therese Michelle
Abstract:: Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...

Numerical Simulation, Laboratory and Field Experiments, Analysis and Design of Wave Energy Converter and Mooring System

Creator:: Lou, Junhui
Abstract:: This dissertation studies the coupled fluid-structure interaction (FSI) of a wave energy converter (WEC) and evaluates the design of a WEC mooring system. The research is conducted in support of conceptual development, field test and performance evaluation of WECs as part of the mission of the Northwest National Marine Renewable...

Development of a Reliability-Based Framework and Empirical Models for Justifying Allowable Chloride Limits and Quantifying Critical Input Variables for Predicting the Service Life of Reinforced Concrete Structures

Creator:: Shakouri Hassanabadi, Mahmoud
Abstract:: Significant progress has been made over the past 20 years in developing models to estimate the service-life of reinforced concrete systems. The basic understandings of the mechanisms that control the transport of ions and moisture in concrete systems have been well researched and models for determining corrosion initiation, specifically chloride-induced...

Understanding Instructors Curriculum Planning Process for the Refinement and Dissemination of a Digital Platform to Share Transportation Education Materials

Creator:: Peters, Allie
Abstract:: Background The National Science Foundation (NSF) has funded multiple research projects dedicated to the development of research and evidence based instructional strategies in an effort to improve the state of science, technology, engineering and math (STEM) education in the US. These efforts have led to an abundance of research based...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

Agent-based Tsunami Evacuation Model : Life Safety and Network Resilience

Creator:: Mostafizi, Alireza
Abstract:: Natural disasters could result in unnecessary loss of life and disproportionate suffering to families and communities if evacuation plans are not in place or understood by the public. In the Pacific Northwest, a magnitude 9.0 earthquake and tsunami from the Cascadia Subduction Zone (CSZ) represents one of the most pressing...

Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

Creator:: Ambauen, Spencer J.
Abstract:: A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...
