Development of an improved system for Oregon to accurately quantify dense-graded hot mix asphalt pavement density

Creator:: Darra, Suraj
Abstract:: The Oregon Department of Transportation (ODOT) standard specifications require a minimum density for the construction of dense-graded hot mix asphalt (HMA) pavements. Currently, the standard specifications call for density measurements for quality control (QC) and quality assurance (QA) testing to be made using nuclear density gauges that are calibrated using...

Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:: Barker, Laura
Abstract:: Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

Behavior and analysis of pile caps with poor anchorage details

Creator:: Sorentino, Anthony William
Abstract:: Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....

Contact and impact dynamic modeling capabilities of LS-DYNA for fluid-structure interaction problems

Creator:: Challa, Ravi
Abstract:: Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI plays a pivotal role in many different types of real-world situations and practical engineering applications involving large structural deformation and material or geometric...

Direction, method, and model for implementing design for construction worker safety in the US

Creator:: Tymvios, Nicholas
Abstract:: The construction industry employs about 7% of the total US workforce, and yet it accounts for 15.7% of all occupational fatalities. Specifically in 2011, there were 721 deaths in construction, second only to transportation with 733. The cause of a large number of these construction deaths can be attributed to...

Initial performance assessment for implementation of hot mix asphalt containing recycled asphalt shingles in Oregon

Creator:: Samoo, Faisal Ahmed
Abstract:: This thesis documents the evaluation of the initial performance of pavement containing recycled asphalt shingles (RAS) in Oregon. The research was funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration and was conducted at Oregon State University. The key objectives of this thesis are to document...

Commercial Motor Vehicle Safety Belt Usage in Oregon

Creator:: Cowgill, Brett Thomas
Abstract:: In ¬¬¬¬2009 the Federal Motor Vehicle Safety Administration (FMCSA) conducted the “Safety Belt Usage by Commercial Motor Vehicle Drivers Survey” for the National Highway Traffic Safety Administration (NHTSA). The survey found that, nationally, 74% of commercial truck drivers wear their safety belts at all times. In the western region of...

Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

Creator:: Loving, Carly K.
Abstract:: Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

Creator:: Kirkham, William J.
Abstract:: There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

A validation of the Oregon State University driving simulator

Creator:: Brown, Lacy S.
Abstract:: Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...
