  • Horizontally curved beam analysis and design

    Creator:
    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....

  • Automated Monitoring of Construction Operations for Data-Driven Decision Making

    Creator:
    Rashid, Khandakar, M.
    Abstract:
    The continuous improvement of construction operations requires a systematic approach of monitoring and making appropriate control actions. However, the lack of real-time information hinders this workflow and eventually compromises timely and effective decision-making. Project managers spend a great deal of time and effort to solve problems emerging from lack of...

  • Framework for assessing the potential safety performance of construction mechanical and electrical field employees

    Creator:
    Moghaddam Vahed, Ali
    Abstract:
    In the field of construction safety, many researchers have worked to create assessment tools. These tools focus on different aspects of construction safety, such as assessing safety climate, safety culture, etc. Although research indicates that the majority of incidents are caused by unsafe behaviors and acts, there are no comprehensive...

  • Implications of Red Signal Countdown Timers on Visual Attention of Oregon Drivers

    Creator:
    Wyman, Amy A.
    Abstract:
    Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard...

  • Investigation of Drilled Shafts under Axial, Lateral, and Torsional Loading

    Creator:
    Li, Qiang
    Abstract:
    Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...

  • 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...

  • Adjacent structure response sensitivity to seismic events using the direct differentiation method

    Creator:
    White, William S.
    Abstract:
    The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...

  • Multi-hazard Damage and Loss Assessment of Bridge Networks

    Creator:
    Burns, Patrick O.
    Abstract:
    The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

  • Assessing Durability of Concrete and Ettringite Accelerated Cementitious System

    Creator:
    Sarkar, Anika T.
    Abstract:
    The goal of the first part of this project was to investigate the influence of aggregate source and entrained air on the transport properties of concrete. Currently, there are several ASTM standards available that provide systematic procedures to evaluate mass transport properties of concrete. ASTM C642-13 (ASTM 2013), often referred...

  • Prediction of monthly streamflows for Oregon coastal basins using physiographic and meteorological parameters

    Creator:
    Orwig, Charles Edwin
    Abstract:
    Prediction equations were developed for estimating the flow regime at ungaged stream locations in the Oregon coastal range. Principal components analysis was used to screen the initial data set of physiographic and meteorological parameters. The final regression equations for predicting mean monthly flow had standard errors of estimate ranging from...
