  • Effect of deposits in Columbia Slough on algae growth in Smith and Bybee lakes

    Creator:
    Sobolewski, William Joseph
    Abstract:
    Currently, the Port of Portland is developing a 9, 410 acre area at the confluence of the Columbia and Willamette Rivers in Multnomah County, Oregon. This area will be developed for industrial, commercial, and recreational use. The recreational development in the North Portland Peninsula area, including the Rivergate Industrial District,...

  • Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

    Creator:
    Smith, Matthew T. (Matthew Todd)
    Abstract:
    Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

  • Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

    Creator:
    Smith, Jeremy A.
    Abstract:
    High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

  • 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...

  • Assessment of Environmental Impacts of Wood Substitution in Commercial Construction

    Creator:
    Milaj, Kristina
    Abstract:
    In the residential sector, wood is the predominant construction material. In the commercial sector and in mid‐rise construction, the use of wood is limited because of a multitude of reasons, including building code restrictions, the perception of wood as a structural material, fire code requirements, and lack of knowledge and...

  • Construction risks allocation : optimal risk allocation decision support model

    Creator:
    Alsalman, Ali Abdullah
    Abstract:
    It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who...

  • Load Path Investigation in a Light-Frame Wood House with Complex Geometry

    Creator:
    Holman, Justin D.
    Abstract:
    The objective of this study was to investigate load paths in an existing light-frame wood structure with complex geometry, using previously established computer modeling methods. The structural model is derived from an existing, multi-level residence located in Corvallis, Oregon. For the purpose of this study, the existing structure was simplified...

  • Evaluation of remediation techniques for circular holes in the webs of wood I-joists

    Creator:
    Polocoser, Tiberiu
    Abstract:
    The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...

  • Biaxial bending of concrete members with applications to prestressed concrete power poles

    Creator:
    Stephens, Charles Talmon
    Abstract:
    A method of analysis of arbitrarily shaped prestressed concrete members for biaxial bending is given. The stress-strain curve of the concrete is represented by two parabolic segments, and the effects of strain hardening of the steel are included in the analysis. An iterative numerical procedure is used to solve for...

    Wong, Yee-chit
    Abstract:
    This paper is a theoretical approach to solve problems of horizontally curved beams Castiglione's theorem is applied to solve for the fixed end bending moments, maximum span moments and fixed end torsional moments. To calculate the vertical deflection at the midspan of the curved beam the moment-area method is used....
