An investigation of Oregon weight-in-motion data for bridge rating implementation and evaluation

Creator:: Pelphrey, Jordan Michael
Abstract:: The LRFR Manual, within commentary Article C6.4.4.2.3, contains provisions for development of site-specific live load factors. In Oregon, truck Weigh-in-Motion (WIM) data were used to develop live load factors for use on state-owned bridges. The factors were calibrated using the same statistical methods that were used in the original development...

Evaluation of estuarine channel conditions in Coos Bay, Oregon using side-scan sonar

Creator:: Hartman, Gregory L.
Abstract:: Side-scan sonar records in Oregon's Coos Bay estuary navigation channels were obtained at intervals of two to three months during the November 1974 - October 1975 time period from Coos Bay Channel Mile 11+50 to 15+20, and from a reach in the Marshfield Channel. A limited side-scan survey effort was...

Static and Wave Equation Analyses and Development of Region-specific Resistance Factors for Driven Piles

Creator:: Bougataya, Youssef
Abstract:: This study uses an existing database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation are used to develop an effective stress-based...

Structural Design and Testing of Mass Timber Concrete Composite Floor Solutions with Acoustic Interlayers

Creator:: Srivastava, Mohit Raja
Abstract:: Timber-concrete composite (TCC) solutions originated in the early twentieth century. There has been a renewed interest in TCC solutions in modern mass timber buildings, especially for floor systems. However due to lack of data, design standards, and code acceptance, TCC solutions require that new mass timber solutions be tested, and...

Hybridized framing to modify load paths and enhance wood shearwall performance

Creator:: Bultena, Sarah M.
Abstract:: Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

Effects of Moisture Intrusion on the Performance of a Cross-Laminated Timber (CLT) Angle Bracket Connection

Creator:: Bora, Shrenik S.
Abstract:: Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...

A Review of Current State Department of Transportation Practice for Promoting and Documenting the Safety of Field Employees

Creator:: Barlow, Zachary Wesley
Abstract:: State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...

Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

Creator:: Schroth, Martin Herbert
Abstract:: Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...

Evaluation of a Pedestrian Call Extension and Cancelation System at a Midblock Trail Crossing

Creator:: Milacek, McKenna
Abstract:: Signalized intersections often provide pushbuttons to call for pedestrian service to minimize conflicting movements between road users. Signalized midblock crossings typically increase safety for pedestrians in locations with high traffic volumes and multiple lanes in each direction. However, unnecessary vehicular delay occurs from “ghost” pedestrian intervals when someone activates the...

A model for simulation of subsurface transport of highway-related water quality constituents

Creator:: Hesse, Edwin Todd
Abstract:: A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all...
