Racking strength of walls : let-in corner bracing, sheet materials, and effect of loading rate by Roger L Tuomi( Book )
6 editions published between 1977 and 1983 in English and held by 76 libraries worldwide
Theoretical and actual racking strength of panels sheathed with fiberboard were closely correlated. Also the dispersion or variability in the data was within normal limits expected for wood-base material. The equations for computing racking strength are independent of panel size, so both simple lateral nall tests and small-scale racking tests could augment the more expensive full-size panel tests. The actual performance of let-in corner braces, without the horizontal board sheathing, is well below the 5,200-pound level cited in the Federal Housing Administration Technical Circular No. 12. Although the strength and stiffness of the brace are important, a level is reached where the stud frame controls ultimate strength. The rate of loading does affect ultimate load for both lateral nall and racking tests. Results of this study, which indicated an 8 to 9 percent increase in strength with a tenfold increase in speed, agree with past studies on the effect of loading rate on strength of wood and wood-base materials
Light-frame wall systems : performance and predictability by David S Gromala( Book )
5 editions published in 1983 in English and held by 76 libraries worldwide
Conventional analysis methods seriously underestimate the strength and stiffness of light-frame wall systems. To better predict the strength and stiffness of these systems, a finite element based computer program, FINWALL, has been developed at Oregon State University (OSU). Previous testing at OSU during model development can now be augmented by the tests described in this paper to provide additional model verification. Test results are presented for 10 walls loaded under a constant axial and uniform increasing lateral load to failure. Failure loads ranged from 88 to 130 pounds per square foot (lb/sq ft) of lateral load, corresponding to about 4 to 6 times design load. Average stud deflections at a common design load of 20 lb/sq ft were 0.09 to 0.21 inch (span/deflection ratio average = 600). Predicted performance, based on the computer model, is compared with test results. Average strength and deflection are predicted at 1.10 and 1.06 times test values, respectively. Model sensitivity to stud failure deflections and problems with load application during some of the tests added considerable variability to the model predictions. Potential applications of the model to codes and standards are discussed
Hardwood Press-Lam crossties : processing and performance by John L Tschernitz( Book )
3 editions published in 1979 in English and held by 29 libraries worldwide
Crossties were made by the Press-Lam process, in which logs are peeled into veneers, dried, and glued into billets in a continuous procedure. Billets were made from 8.5-foot-long veneers and from 4-foot-long veneers, cut into final product dimensions, and treated with preservative. In laboratory tests, bending strength and stiffness of the Press-Lam ties were found to exceed those of solid-sawn red oak crossties; shear strength was only adequate. Tie wear tests showed low surface wear for laminated ties, comparable to the performance of solid specimens. Results of spike driving tests, however, indicated problems in some species. All Press-Lam ties met the performance criteria in the cyclic delamination tests, and, in lateral resistance tests, Press-Lam ties were not significantly different from solid-sawn ties. Volume yields are discussed and cost estimates are provided for use in calculating total tie costs for specific cases
