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)...
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...
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 objective of this research is to use a three-dimensional (3D) analysis
method to include 'system effects' directly in the design of light-frame roof truss
assemblies. The goal of this study is to develop an improved and practical method to
determine the structural performance of 3D roof truss assemblies used...
Current compression perpendicular-to-grain (c-perp) design values for wood members are based on mean stress using the ASTM D143 specimen. Base design value, as determined from 0.04-in deformation in the ASTM specimen, is applied to all c-perp applications. While the standard ASTM test was presumably believed to adequately reflect relevant c-perp...
It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...
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...
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...
The overall goal of this study was to evaluate an alternative to
traditional wood framed shear wall construction. This study introduced the
innovative idea of using a water and seismic damage resistant, wood-concrete-
composite (WCC) construction instead of an all-wood design. The
WCC design consisted of a thin shell of...
Friction dampers have been used successfully to dissipate seismic
energy in steel and concrete structures. The application is new to timber
structures. The objectives of this research were to design a slotted bolted
connection (SBC) and evaluate its potential as a passive energy damper in
timber brace.
The research was...
