Laboratory performance of highway bridge girder anchorages under hurricane induced wave loading

Creator:: Lehrman, Jora
Abstract:: Many bridges along the Gulf Coast of the United States were damaged by recent hurricanes, and many more are susceptible to similar damage. This research examines performance of common anchorage connection details for AASHTO Type III prestressed concrete girders used by some transportation agencies. Full-scale specimens were fabricated and tested...

Lava Flow Lobation and Margin Analysis

Creator:: Peckyno, Robert S.
Abstract:: Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...

The impacts of mining legacy in a water-scarce South Africa : An environmental security perspective

Creator:: Hanlon, Thomas M.
Abstract:: Given the growing human security implications resulting from the high rates of change in social-ecological systems, the general question motivating this research is: how can the traditional security establishment respond to rising non-traditional threats? This question comes from the ongoing debate of whether military resources should be used in some...

Flexural steel anchorage performance at diagonal crack locations

Creator:: Triska, Mary Ann
Abstract:: Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

Creator:: Goodall, Joshua K.
Abstract:: Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

Examinations of Fusarium sambucinum on Humulus lupulus and co-infection with hop stunt viroid in commercial hop fields

Creator:: Cerruti, Natasha R.
Abstract:: After an unusually high incidence of Fusarium canker was observed in commercial hop fields of the Pacific Northwest, field surveys were conducted and revealed that canker incidence ranged from 20 to 60% of bines sampled in six commercial fields, as well as wide-spread Hop stunt viroid infection in these six...

Assessing mental workload and situation awareness in the evaluation of real-time, critical user interfaces

Creator:: Strawn, Jordan J.
Abstract:: While there are many ways to evaluate a user interface design, the user's mental workload and situation awareness (SA) are particularly important considerations in the supervisory control of safety-critical systems. Typically, operators of these systems must monitor high-volume, time-sensitive status information. Interface design for this domain can be challenging and...

Utilizing emergent web-based software tools as an effective method for increasing collaboration and knowledge sharing in collocated student design teams

Creator:: Koch, Michael D.
Abstract:: Over the last few decades, the methods and tools through which humans collaborate, share knowledge and generally communicate have been advancing at a rapid pace. Thanks mostly to advances in broadband internet, cheap data storage and fast microprocessors, humans now have the ability to work together in ways that even...

An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

Post-breeding habitat selection by songbirds in the headwaters of the Trask River, northwestern Oregon

Creator:: Jenkins, Stephanie R.
Abstract:: Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...
