  • 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...

  • Numerical Modeling of Mass Timber Connections

    Creator:
    Hollenbeck, Sean R.
    Abstract:
    Cross-Laminated Timber (CLT) is a prefabricated building material that is relatively new to the United States and North America. It consists of no less than three layers of graded, dimensional lumber glued in alternating longitudinal and transverse layers to create a panel that can be used for various building applications...

  • Pressure sensitive adhesives based on oleic acid

    Creator:
    Wu, Yili
    Abstract:
    Existing pressure sensitive adhesives (PSAs) are mostly based on petrochemicals. In this study, a novel PSA based on a renewable material, methyl oleate, was prepared and characterized. Methyl oleate was first epoxidized to form epoxidized methyl oleate that was subsequently hydrolyzed and acidified to form epoxidized oleic acid (EOA) which...

  • Bending property enhancement of wood strand composite using viscoelastic thermal compression

    Creator:
    Rathi, Vardan M.
    Abstract:
    The fundamental intent of the study was to develop an innovative wood-strand composite for use in structural applications. Plantation grown, low density, hybrid poplar was used in the study which was found to be appropriate for the underlying Viscoelastic Thermal Compression (VTC) process. Wood modified by this process has high...

  • Analysis of adhesive atomization on composite bond performance

    Creator:
    Willard, Dylan T.
    Abstract:
    Spraying of liquid adhesive onto wood surfaces has shown to be a highly effective and efficient method of application across many different wood-based composite industries. However, the dynamics of spraying are extremely variable and distribution can be affected by liquid properties (rheology, molecular weight distribution, and temperature), application parameters (disk...

  • Effective Bonding Parameters for Hybrid Cross-Laminated Timber (CLT)

    Creator:
    Larkin, Blake
    Abstract:
    Cross-laminated timber (CLT) is a massive engineered wood product made of orthogonally bonded layers of solid-sawn lumber, and is intended for roof, floor, or wall applications. Although it was developed in Europe in the early 90s, CLT is relatively new to North America. CLT products must be certified for structural...

  • Evaluation of new formaldehyde-free, soy flour-based wood adhesives for making particleboard

    Creator:
    Gu, Kai
    Abstract:
    Formaldehyde-based adhesives such as urea-formaldehyde (UF), phenol-formaldehyde (PF) are widely applied in wood-based composite industry. However, these adhesives are all petrochemical-based and could not sustain in a long term due to a limited reserve of oil and natural gas. Moreover, these adhesives emit carcinogenic formaldehyde in the production or use...

  • Direct coupling of imaging to morphology-based numerical modeling as a tool for mechanics analysis of wood plastic composites

    Creator:
    Lin, Xiang
    Abstract:
    Polymeric composites reinforced with bio-materials have advantages over composites with synthetic reinforcements. Bio-based composites use low-cost and renewable reinforcements, have nonabrasive properties for machining, have improved damping characteristics, and have potential for energy recycling. However, the limited use of bio-based composites is because their mechanical properties are typically much lower...

  • Behavior of a 1/6th scale, two-story, wood framed residential structure under surge wave loading

    Creator:
    Wilson, Jebediah
    Abstract:
    The goal of this study was to develop an understanding of the nature of surge wave loading on wood framed residential structures for a variety of building configurations and test conditions. The objectives of the study were: (1) to measure forces on a 1/6th scale wood framed residential structure, (2)...

  • 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...
