The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...
Torsion test was evaluated as a method to determine the shear strength
parallel to grain of full-size structural composite lumber (SCL). Experimental
results of eighty-five rectangular (44 x 140 mm²) specimens were verified by finite
element analysis. Laminated strand lumber (LSL), laminated veneer lumber
(LVL) and parallel strand lumber (PSL)...
The torsion test was evaluated as a method for determining the shear
strength of full-size structural lumber. The evaluation involved an experimental
length study, an experimental depth study, and a finite element study.
The length study consisted of fifty nominal 2x4 specimens, ten specimens
for each length, and ten American...
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)...
Many nondestructive techniques for structural health monitoring are subjective and based on visual observations of degradation. In addition, dynamic properties of structures are already used to obtain quantitative structural health data. However, most current data collection is limited to localized damage on the structure, rather than global response. Recent research...
The objectives of this study were to evaluate the performance of wood frame shear walls
under monotonic, cyclic and earthquake loads by: (1) estimating the variability of shear wall
performance, (2) comparing the performance of walls under each loading protocol, (3) evaluating
the effects of anchorage on wall performance, and...
The overall goal of this study is to evaluate the earthquake performance of wood frame
shear walls, and more specifically: (1) to compare the performance differences of fully and
partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall
performance under earthquake loads with that of standardized...
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...

The goal of this project is to contribute to the development of design values for cross-laminated timber (CLT) diaphragms in the seismic load-resisting system for buildings. Monotonic and cyclic tests to determine strength and stiffness characteristics of 2.44 m (8 ft) long shear connections with common self-tapping screws were performed....
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...
