Creator:: Lucksiri, Kraisorn, Miller, Thomas H., Gupta, Rakesh, Pei, Shiling, and van de Lindt, John W.
Abstract:: A numerical investigation is presented on effects of plan configuration on seismic responses of single-story, wood-frame dwellings. 151 models were developed using observations of 412 dwellings of rectangular, L, T, U, and Z-shapes in Oregon. A nonlinear, time-history program, Seismic Analysis Package for Wood-frame Structures, was the analysis platform. Models...

Abstract:: Ten full-size (3.7×4.9m) plywood roof diaphragms were constructed using metal-plate-connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67, and 100%, a hip roof of 33% slope, and a flat roof, with a horizontal bottom...

Abstract:: There are about 80 million single-family dwellings (SFDs) in the United States, predominantly of wood-frame construction. Of these, 68% are owner-occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all the houses in...

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....

Creator:: Seaders, Peter, Miller, Thomas H., and Gupta, Rakesh
Abstract:: The objectives of this study were to evaluate the performance of wood-frame shear walls under monotonic, cyclic, and earthquake loads by: 1) comparing performance under each loading protocol; 2) evaluating effects of anchorage; and 3) eval-uating performance qualitatively and quantitatively with respect to code-deﬁned performance measures. Tests were conducted on...

Creator:: Seaders, Peter, Gupta, Rakesh, and Miller, Thomas H.
Abstract:: The objectives of this study were to evaluate the performance of wood-frame shear walls under monotonic and cyclic loads by: 1) determining variability of shear wall performance; 2) comparing performance of walls under each loading protocol; 3) evaluating effects of anchorage on wall performance; and 4) evaluating performance of walls...

Creator:: Gupta, Rakesh and Siller, Tobias S.
Abstract:: The objective of this study was to compare the shear strength of structural composite lumber (SCL) based on shear block to that of shear strength based on torsion test. Shear blocks in two diflcrent orientations fom laminated veneer lumber, parallel strand lumber, and laminated strand lumber (LSL) were tested and...

Creator:: Gupta, Rakesh and Limkatanyoo, Pranueng
Abstract:: The objective of this research was to use a three-dimensional (3D) analysis method to evaluate “system effects” in light-frame roof truss assemblies. The goal of this study was to develop an improved and practical design method for 3D roof truss assemblies used in residential construction. A truss plate manufacturer (TPM)...

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...

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...
