Light-frame versus timber frame : a study in quantifying the differences

Creator:: Malone, Brian P.
Abstract:: The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

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...

Identifying and prioritizing research gaps for the incorporation of fires in life cycle analysis of structures: A Delphi survey of international experts

Creator:: Thorp, Tiana Noelani
Abstract:: Civil engineers are aware of the impacts of structures on the global environment but the environmental impacts of a fire within these structures remains unknown. Fires present a unique hazard as it is difficult to predict the probability of the occurrence and the intensity. Traditional methods to identify the environmental...

Practical modeling for load paths in a realistic, light-frame wood house

Creator:: Pfretzschner, Kathryn S.
Abstract:: The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified 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...

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,...

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...

Moisture effects on properties of wood-composite assemblies

Creator:: King, David
Abstract:: Engineered wood composites are used in many structural applications and are intended for dry use. However, these materials may encounter significant amounts of wetting while in service, which can lead to structural failures. This study combined aspects of wood science, mechanics, structural engineering, and mycology to assess changes in material...

The effects of nail bending-yield stress and biological deterioration on the cyclic performance of shearwalls

Creator:: Anderson, Erin N.
Abstract:: Key parts of the lateral force resisting system in wood-frame buildings are the shearwafls and the connections. The connections in wooden buildings are the primary source of ductility and energy dissipation; these are essential properties when buildings are exposed to lateral forces, such as wind and earthquakes. Shearwall design is...
