Polar analysis of beam-columns for aircraft

Creator:: Jones, Walter Richard
Abstract:: The analysis of a member carrying a combination of lateral and axial loads (a "beam-column") is a problem of frequent occurrence in aircraft structural design. This thesis presents the derivation and application of the Polar method, both analytical and graphical. The method was first suggested in Germany, several years later...

Petroleum refinery residuals : a recycling feasibility study

Creator:: Hoffman, Andrew J.
Abstract:: Large quantities of unused heavy oil and residual waste products from the petroleum refining industry were deposited in on-site landfills, pits, and lagoons, prior to the promulgation of regulations governing their disposal and technology development that would further utilize and/or recycle these materials. Contacting petroleum products with sulfuric acid for...

Bond strength investigations and structural applicability of composite fiber-reinforced polymer (FRP) rebars

Creator:: Kachlakev, Damian I.
Abstract:: The composite FRP rebars research at Oregon State University was initiated in 1993 principally to develop a non-metallic hollow reinforcement. It was recognized that the tensile properties of such reinforcement are unquestionably superior to steel, but its performance in concrete could be problematic. The bond between FRP rebars and concrete...

Evaluation of crumb rubber modified mixtures using performance based analyses

Creator:: Saxton, Robert W.
Abstract:: This study investigated the laboratory performance of crumb rubber modified mixtures compared to a standard bituminous mixture using performance based test procedures. This study was part of an asphalt resurfacing program for the Seattle Washington area. Laboratory analyses were used to estimate the long term pavement performance of these mixtures...

Early age performance of latex-modified concrete bridge deck overlays

Creator:: Sujjavanich, Suvimol
Abstract:: Environmental factors and physical properties of latex modified concrete (LMC) are hypothesized to contribute to early age cracking in bridge deck overlays. Cracking permits the ingress of moisture and aggressive solutions into the substrate and may contribute to other subsequent distresses. Understanding the material properties and mechanisms involved is necessary...

Permanent deformation characteristics of dense-graded mixes using asphalt pavement analyzer

Creator:: Sandoval-Gil, Jesus A.
Abstract:: The Asphalt Pavement Analyzer (APA) device was used to characterize the impact of various mix factors on the development of permanent deformation in dense-graded mixes given a standard compactive effort. Factors included two aggregate sizes, three VMA levels, two fines contents, three binder contents and four binder types. All specimens...

The evaluation of the field vane shear strength analysis of the Glen Aiken creek embankment failure

Creator:: Clarke, James Dennis
Abstract:: A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...

The control and fate of enteric bacteria in the environment with particular emphasis on the factors influencing fecal indicator survival in waste storage facilities

Creator:: Crane, Stuart R.
Abstract:: The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...

Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

Creator:: Slaven, Kelli R.
Abstract:: The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

Prediction of low temperature cracking of asphalt concrete mixtures with thermal stress restrained specimen test results

Creator:: Kanerva, Hannele K.
Abstract:: Low temperature cracking is attributed to tensile stresses induced in an asphalt concrete pavement that develop when the pavement is subjected to a cold temperature. Cracking results in poor ride quality and a reduction in service life of the pavement. Low temperature cracking has been predicted by regression equations, mechanistic...
