  • Structural Design and Testing of Mass Timber Concrete Composite Floor Solutions with Acoustic Interlayers

    Creator:
    Srivastava, Mohit Raja
    Abstract:
    Timber-concrete composite (TCC) solutions originated in the early twentieth century. There has been a renewed interest in TCC solutions in modern mass timber buildings, especially for floor systems. However due to lack of data, design standards, and code acceptance, TCC solutions require that new mass timber solutions be tested, and...

  • Hybridized framing to modify load paths and enhance wood shearwall performance

    Creator:
    Bultena, Sarah M.
    Abstract:
    Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

  • 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 effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

    Creator:
    Sinha, Arijit
    Abstract:
    Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

  • 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...

  • Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

    Creator:
    Kirkham, William J.
    Abstract:
    There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

  • 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...

  • The effect of hold-down misplacement on the strength and stiffness of wood shear walls

    Creator:
    Lebeda, Dana J.
    Abstract:
    The objective of this study was to determine the effect of misplaced hold-downs on the static and cyclic behavior of wood shear walls. Three shear wall configurations were considered in this study. The first configuration (control) had hold-downs at the ends of the wall (wall type 1), the second configuration...

  • Wood materials and shearwalls of older light-frame residential structures

    Creator:
    Carroll, Cameron T.
    Abstract:
    Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

  • The Fundamental Behavior of CLT Floor-to-Wall Connections in Fire

    Creator:
    Redus, James Aaron
    Abstract:
    This thesis focuses on the fundamental behavior of CLT floor-to-wall connections during a fire. Cross-laminated timber (CLT) panelized structures rely on floor-to-wall connections for the load path and stability of the structure. Additionally, the fire performance of these connections is critical to prevent horizontal or vertical fire spread within these...
