  • Effects of Moisture Intrusion on the Performance of a Cross-Laminated Timber (CLT) Angle Bracket Connection

    Creator:
    Bora, Shrenik S.
    Abstract:
    Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...

  • The Fundamental Behavior of Timber-Concrete Composite Floors in Fire

    Creator:
    Shephard, Annabel B.
    Abstract:
    Timber-concrete composite (TCC) floors have improved strength and stiffness when compared to timber-only floors, allowing for longer spans in buildings and improved life safety. However, North America does not have codes and standards that recognize TCC floors, particularly the improved life safety performance of these floors in fire. Therefore, alternate...

  • Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

    Creator:
    Beairsto, Cody J.
    Abstract:
    Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

  • A Methodological Approach for Structural Health Monitoring of Mass-Timber Buildings Under Construction

    Creator:
    Baas, Esther J.
    Abstract:
    As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...

  • 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...

  • In-Plane Shear Performance of Cross-laminated Timber and Cross-laminated Timber Concrete Composite Diaphragm Connection Systems

    Creator:
    Taylor, Brad
    Abstract:
    Cross-laminated timber (CLT) panels have been gaining popularity as diaphragm elements in mid- to high-rise construction projects. In addition, CLT-concrete composite (CCC) diaphragms have been implemented to expand the use of CLT diaphragms. To understand the behavior of CLT and CCC diaphragms, this research effort sought to characterize the cyclic,...

  • Multi-Scale Dynamic Monitoring and Behavior of Cross-Laminated Timber Elements and Systems

    Creator:
    Mugabo, Ignace
    Abstract:
    Cross-Laminated Timber (CLT) is one of the latest engineered wood products to show promising structural features for a variety of structural purposes including resisting lateral loads. For CLT to be widely adopted, its modal behavior needs to be fully evaluated through experimental and numerical methods. It is important to the...

  • Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

    Creator:
    Anderson, Christopher H.
    Abstract:
    Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...

  • Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

    Creator:
    Mahr, Kolton J.
    Abstract:
    Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...

  • Cross-Laminated Timber Shear Walls with Toe-Screwed and Slip-Friction Connections

    Creator:
    Fitzgerald, Dillon M.
    Abstract:
    Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...
