Establishing a through-boring pattern and method of test for utility poles

Creator:

Elkins, Lori A.

Abstract:

The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

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...

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...

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...

Effect of Hole Edge Distance on Strength of Through-Bored Utility Poles

Creator:

Romanaggi, Bennett T.

Abstract:

There are over 130 million wood poles supporting electrical transmission and distribution lines in the U.S. The vast majority of these poles are preservative treated to prolong their useful life. In some cases, however, the depth of treatment is relatively shallow, leaving a deep zone of moderately durable, untreated heartwood....

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...

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...

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...

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...

Strain distribution in OSB and GWB in wood frame shear walls

Creator:

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...
