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...

Development of rapid visual screening tool for seismic evaluation of wood-frame dwellings

Creator:: Lucksiri, Kraisorn
Abstract:: During the past several decades, earthquakes have caused extensive damage to buildings, including wood-frame, single-family dwellings, in the United States. In order to mitigate future losses, existing buildings in earthquake prone areas should be evaluated for their seismic safety. This is also an important issue for buildings in Oregon due...

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...

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...

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...

Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...

The impact of wood variability on the drying rate at different moisture content levels

Creator:: Berberović, Adin
Abstract:: Variability in wood properties causes boards within a stack of lumber to dry at different rates and reach different moisture content levels after drying is completed. The consequence is that the boards will have properties that differ from ones that were intended to be achieved by the drying process. The...

Non-destructive evaluation of veneer using optical scanning and ultrasonic stress wave analysis systems

Creator:: DeVallance, David B.
Abstract:: Non-destructive commercial ultrasonic grading provides laminated veneer lumber (LVL) manufacturers a means for sorting veneer based on average ultrasonic propagation time (UPT) and/or average dynamic modulus of elasticity (MOEd). While this may provide reliable estimations of modulus of elasticity (MOE), little is known about the influence of veneer defects on...

Oils Colored with Wood-Staining Fungal Pigments : Color Loss, Oxidation, and Structural Breakdown

Creator:: Hinsch, Eric M.
Abstract:: Wood-staining fungal pigments have potential uses as colorants for wood and textiles. Traditionally, organic solvents have been used as carriers for these pigments. However, other environmentally-friendly and more readily available carriers must be found. Natural oils have the potential to carry these pigments but have demonstrated color loss over relatively...

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...
