Performance of Pressure Sensitive Adhesive Tapes In Wood Light-Frame Shear Walls
The performance of connections and full-scale shear walls constructed with acrylic foam pressure sensitive adhesive (PSA) tape is the focus of this thesis. The objectives of this study were first to investigate the bonding characteristics of adhesive tape to wood substrates and then to expand this …

Performance Capabilities of Light-Frame Shear Walls Sheathed With Long OSB Panels
… blocking members between the studs of the frame. Values obtained from the tests performed on these walls provided a direct comparison to those obtained from the walls of equal height, but sheathed with a long panel capable of spanning the entire height of the wall. The capabilities of long …

The Effects of Diaphragm Flexibility on the Seismic Performance of Light Frame Wood Structures
… flexibility on the seismic performance of light frame wood structures (LFWS). The finite element approach is considered for modeling LFWS as it is more detailed and provides a way to explicitly incorporate individual structural elements and corresponding material properties. It is also …

Investigating the Performance of Wood Portal Frames as Alternative Bracing Systems in Light-Frame Wood Buildings
Light-frame shearwall assemblies have been successfully used to resist gravity and lateral loads, such as earthquake and wind, for many decades. However, there is a need for maintaining the structural integrity of such buildings even when large openings in walls are introduced. Wood portal frame …

Investigation of Modular Cross-Laminated Timber Rocking Walls and Rocking Wall -- Light-Frame Shear Wall Dual Systems for Seismic Resilience
… lateral force resisting systems (LFRS) with wood light frame shear walls (LiFS). The first part of this dissertation details the experimental cyclic testing of six large-scale PT-CLT-RW with modular base connections. The tests were designed to replicate the first story of low- to mid-rise mass …

An Investigation of Nailed Connection Performance in a Cyclic Humidity Environment
… cyclic moisture infiltration on connections in light-frame wood buildings has received limited research attention. Specifically, the connections between wood-based sheathing materials (OSB, plywood) and solid wood studs are of interest. A comprehensive understanding of connection performance …

Modernizing the passing joint : a standardized building system to facilitate contemporary bamboo housing construction in regions of economic constraint
… been incorporated into the history of standard light frame wood construction and is therefore not used to its full potential, especially in regions of economic constraint in greatest need of housing structures. Can we design a light-frame construction system that allows for the non-standard …

Effect of Overturning Restraint on the Performance of Fully Sheathed and Perforated Timber Framed Shear Walls
… the monotonic and cyclic response of light-frame wood shear walls with and without openings. Effects of overturning restraint in the form of tie-down anchors and corner segments on light-frame shear walls with and without door and window openings were quantified. While the results are …

Modeling the behavior of wood-based composite sheathing under hygrothermal load
In light-frame residential construction wood-based composite panels used externally or internally are exposed to relative humidity and/or temperature changes. The subsequent moisture content change of the panels will result in two types of deformations as follows: 1. elastic deformation of the …

The influence of load distribution on the reliability analysis of lumber properties data
… the statistical nature of loads acting on light frame structures, distributions of maximum lifetime roof snow load and maximum lifetime floor live load were developed for use in differential reliability analyses of lumber properties data. The dead load was combined with the live load to …

Potential of cross laminated timber in single family residential construction
… for smaller scale projects, especially light frame wood (LFW) residential construction. The purpose of this study is to provide a detailed comparison of the cost to construct a CLT home versus a LFW home to quantify the cost difference between both options in the single family home (SFH) …

Free4orm framing : high-performance bending-active strip construction
This thesis re-thinks conventional light frame and panelized construction methodologies employed in residential and general medium-scale construction. To do so, it investigates the flexural geometry, the structural performance, and volumetric approaches to systematizing elastically bent developable …

Design of Stick-Framed Wood Roofs Under Extreme Wind Loads
Light-frame wood construction comprises nearly 90% of the housing industry inCanada and the United States. The roofs of these houses can be constructed eitherentirely on site or using prefabricated trusses. Assembling the roof structure on site,otherwise known as stick-framing, is a framing …
