Destructive testing of metal-plate-connected wood truss joints.

Creator:: Rakesh Gupta and Kifle G. Gebremedhin
Abstract:: Load-displacement characteristics and failure modes of metal-plateconnected wood truss joints are presented. Tension splice, heel, and web at the bottom chord joints are fabricated using southern pine (SP) no. 2 lumber and 20-gage punched metal plates. These joints are tested with a newly developed testing appratus that allows the testing...

Analysis of metal-plate-connected wood trusses with semi-rigid joints

Creator:: Gupta, R., Gebremedhin, K. G., and Cook, J. R.
Abstract:: Metal-plate-connected wood trusses with semi-rigid joints were investigated by the matrix method of structural analysis. The element-stiffness matrix and fixed-end forces of an individual member with one or both ends semi-rigid were derived as modifications of the idealized cases. The case of unequal elastic connections at two ends of a...

An expert system for optimizing computer aided design of post frame buildings

Creator:: Gebremedhin, K. G., Jagdale, S. S., and Gupta, R.
Abstract:: A procedure has been developed to optimize designs of metal-clad post-frame buildings using an expert system. The novel part of the study is the development of a procedure that extends the solution of an engineering problem from a conventional algorithmic Computer Aided Design (CAD) program to be used by the...

Metal-plate-connected wood joints : a literature review

Creator:: Gupta, Rakesh, Vatovec, Milan, Miller, Thomas H., and Oregon State University. Forest Research Laboratory
Abstract:: "This publication has presented an overview of current research on MPC joints in wood trusses. The literature search was primarily of U.S. sources, with some effort to obtain literature from other parts of the world. An enormous amount of important information has been amassed by studies on testing procedures and...

State of the Art: Seismic Behavior of Wood-Frame Residential Structures

Creator:: Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.
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...

Effects of Roof Pitch and Gypsum Ceilings on the Behavior of Wood Roof Diaphragms

Creator:: Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.
Abstract:: Ten full size (3.7 x 4.9 m) 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...

Modeling of metal-plate-connected wood truss joints

Creator:: Vatovec, M., Miller, T. H., and Gupta, R.
Abstract:: A commercially available, three-dimensional finite-element analysis software was used to model the load-displacement behavior of metal-plate-connected (MPC) joints in wooden trusses. Model features included consideration of material properties, teeth-to-grain-to-direction-of-force orientation, wood-to-wood interaction, and gaps between wood members. To simulate wood-to-plate interaction, the main feature of the model, each tooth of...

Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:: Gedil, Melaku Ayele
Abstract:: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...
