  • Seismic performance and collapse assessments of reinforced concrete lateral- force resisting systems

    Creator:
    Buniya, Mustafa Kamil
    Abstract:
    Nonlinear response history analysis (NRHA) is increasingly becoming more accessible and prevalent in research and practice. As the accuracy of the NRHA results depends on the ground motion characteristics and the robustness of the numerical model, research has focused on the development of guidance for performance-based seismic design and assessment...

  • Cyclic performance of connections used in hybrid cross-laminated timber

    Creator:
    Mahdavifar, Vahid
    Abstract:
    One of the recent additions to the panoply of engineered wood products is cross-laminated timber (CLT). CLT is a prefabricated, large-scale, solid wood panel that consists of multiple layers of lumbers stacked together, with each layer arranged perpendicular to the next layer, glued with structural grade adhesives, and pressed. The...

  • Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

    Creator:
    Rohani, Joshan W.
    Abstract:
    Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...

  • Lateral Load Path Analysis : Practical Methods for Light-Frame Modular Structures

    Creator:
    Huynh, Thanh Q.
    Abstract:
    The objectives of this study are to use SAP2000 to investigate lateral load paths and system behavior in a modular, light-frame wood structure by investigating different foundation configurations and to further develop and validate existing modeling techniques of shear wall elements based on the Perforated Shear Wall Method. The modeling...

  • Risk and reliability associated with use and reuse of vertical formwork

    Creator:
    Das, Amrutha
    Abstract:
    Concrete formwork is a common type of temporary structure used on construction projects. Due to difficulties in considering actual construction site implications during formwork design, assessments of formwork integrity are often made in the field by site personnel based on subjective visual inspection. The use and re-use of concrete formwork...

  • Modeling Unobserved Heterogeneity and the Injury Severities of Truck Drivers in Run-Off-Road (ROR) Crashes: Econometric Methods and Applications

    Creator:
    Al-Bdairi, Nabeel Saleem Saad
    Abstract:
    Recent statistics regarding large truck crashes reveal that fatality rates of large trucks per 100 million vehicle miles traveled (VMT) and fatality rates per 1,000 registered vehicles are higher than those for passenger vehicles. These statistics underscore the need for greater efforts by safety professionals to help mitigate the impacts...

  • GOSEP: Georeferenced Oregon Soil Engineering Properties

    Creator:
    Dutille, Victoria L.
    Abstract:
    Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

  • The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

    Creator:
    Kim, Jaekook
    Abstract:
    Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...

  • Numerical Analysis of a Spine as a Retrofit of a Moment-Resisting Frame

    Creator:
    Rivera Torres, David M.
    Abstract:
    Steel moment-resisting frames (MRFs) are widely used in the United States to resist seismic forces. MRFs have many advantages, including architectural versatility, vetted member and connection detailing requirements, and high ductility for special MRFs (SMRF). However, MRFs require large members to meet story drift criteria. Moreover, strong-column-weak-beam requirements can result...

    Warner, Skyler J.
    Abstract:
    The use of fly ash as a supplementary cementitious material (SCM) has increased in the last century due to its various environmental benefits as a recycled product. Within the last 60 years, it has been found that it can be used to effectively control damage induced by Alkali-Silica Reaction. However,...
