  • 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...

  • 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...

  • Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

    Creator:
    Langlois, Jeffrey D.
    Abstract:
    The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...

  • 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...

  • Evaluation of the torsion test for determining the shear strength of structural lumber

    Creator:
    Heck, Leanne Renee
    Abstract:
    The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...

  • Strain distribution in OSB and GWB in wood frame shear walls

    Creator:
    Sinha, Arijit
    Abstract:
    The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

  • Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

    Creator:
    Tjahyadi, Alfred
    Abstract:
    Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...

    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...
