Revisiting the neutral axis in wood beams

Creator:: Davis, Philip M., Gupta, Rakesh, and Sinha, Arijit
Abstract:: For wood beams, it is often assumed that the neutral axis (NA) is located at the centroid of the beam. This would be the case for isotropic and homogeneous materials but these prerequisites are not valid for wood. The varying grain patterns and knots located throughout wood make wood anisotropic...

Effect of grain angle on shear strength of Douglas-fir wood

Creator:: Gupta, Rakesh and Sinha, Arijit
Abstract:: The effect of grain angle (GA) on shear strength of Douglas-fir has been evaluated. Shear block specimens with a GA varying from 0 to 90° was loaded in the shear plane, resulting in failure mode transitioning from parallel to grain shear to rolling shear. As expected, shear strength decreased as...

Characterizing perpendicular-to-grain compression (C-perpendicular to) behavior in wood construction

Creator:: Basta, Craig Thomas, Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Current compression perpendicular-to-grain (C-perpendicular to) design values for wood members are based on mean stress obtained from ASTM D143 specimen. The standard ASTM test with metal on wood bearing has limited applicability in modern construction assemblies with C-perpendicular to loading scenarios. Previous work has shown that end-bearing conditions and wood-on-wood...

The effect of elevated temperature exposure on the fracture toughness of solid wood and structural wood composites

Creator:: Sinha, Arijit, Nairn, John A., and Gupta, Rakesh
Abstract:: Fracture toughness of wood and wood composites has traditionally been characterized by a stress intensity factor, an initiation strain energy release rate (G[subscript init]) or a total energy to fracture (G[subscript f]). These parameters provide incomplete fracture characterization for these materials because the toughness changes as the crack propagates. Thus...

Sustainable Development and Green Buildings

Creator:: Sinha, Arijit, Gupta, Rakesh, and Kutnar, Andreja
Abstract:: Global sustainability goals have led to the development of the green building movement. The Green Building Program, stemming from the movement, has had unprecedented success as it provides a quantifi able metric to people’s efforts towards sustainable development. Sustainable development and green buildings are often used interchangeably. Although, sustainable development...

Thermal degradation of bending properties of structural wood and wood-based composites

Creator:: Sinha, Arijit, Gupta, Rakesh, and Nairn, John A.
Abstract:: Wood and wood-based composites are being used extensively in single-family residential dwellings. Therefore, it is important to categorize their response when exposed to elevated temperatures for a sustained period of time. In fire-resistant design for wood structures, the main goal is to ensure that enough structural integrity is maintained, during...

Applications of perpendicular-to-grain compression behavior in real wood construction assemblies

Creator:: Basta, Craig T., Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Compression perpendicular to grain (C┴) of wood is an important property and has a drastic effect on serviceability of the structure. Typical C┴ loading scenarios include the bottom chord of a truss resting on the top plate of a shear wall and chords of a shear wall resting on the...

Characterizing perpendicular-to-grain compression (C⊥) behavior in wood construction

Creator:: Basta, Craig Thomas, Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Current compression perpendicular-to-grain (C⊥) design values for wood members are based on mean stress obtained from ASTM D143 specimen. The standard ASTM test with metal on wood bearing has limited applicability in modern construction assemblies with C⊥ loading scenarios. Previous work has shown that end-bearing conditions and wood-on-wood C⊥ bearing...

Thermal Degradation of Lateral Yield Strength of Nailed Wood Connections

Creator:: Sinha, Arijit, Gupta, Rakesh, and Nairn, John A.
Abstract:: This study investigated the effect of exposure to elevated temperature on the yield strength of single-shear nail connections when subjected to lateral loading. Solid sawn lumber and laminated veneer lumber were used as framing members and two different thicknesses of both oriented strand board and plywood were used as the...

Thermal degradation of bending strength of plywood and oriented strand board: a kinetics approach

Creator:: Sinha, Arijit, Nairn, John A., and Gupta, Rakesh
Abstract:: The construction industry has relied heavily on wood and wood-based composites, such as oriented strand board (OSB) and plywood for timber frame construction. Therefore, it is highly imperative to categorize the response of wood-based composites when exposed to elevated temperatures for a sustained period of time. The essence of fire-resistant...

Seismic Laboratory Testing of Energy-Efficient, Staggered-Stud, Wood-Frame Shear Walls

Creator:: Rodriguez-Nikl, Tonatiuh, Gupta, Rakesh, Kramer, Anthonie, and Sinha, Arijit
Abstract:: Residential energy use is a significant contributor to greenhouse gas emissions and climate change. Reducing energy efficiency in conventional wood-framed houses are thermal bridges: direct paths that allow heat to flow through the studs instead of the insulation. One suggestion for reducing thermal bridging is the staggered stud (SS) wall....
