In recent years wood strength researchers have begun to replace experimental unit allocation via random sampling with allocation via sorts based on nondestructive measurements of strength predictors such as modulus of elasticity and specific gravity. Although this procedure has the potential of greatly increasing experimental sensitivity, as currently implemented it can easily reduce sensitivity. In this paper we discuss the problem and we present solutions. Given the existence of nondestructive measurements of strength predictors, our methods can be used to reduce sample sizes. We have written a public domain computer program that implements the methods.

Wood is one of the most intriguing structural materials and the only one that is truly renewable. Along with stone, wood is the oldest structural material on the planet and has been extensively used throughout human history. Due to its aesthetical value and positive environmental impact, wood has experienced a renaissance in construction. As a biodegradable, hygroscopic, non-isotropic material, wood presents special challenges for a professional and requires through knowledge ranging from biology to continuum mechanics. This state-of-the-art report reflects the current knowledge in the area of in situ assessment of the physical and mechanical properties of wood structures. Nondestructive, semi-destructive and destructive methods are described in a systematic manner where technology, equipment and limitations are discussed. Some of the discussed methods are used in other materials such as masonry and concrete. Most of the methods, however, are specific to wood and special qualifications are required to understand and apply these methods effectively. Existing methods are constantly improved and new methods are being developed. This report includes methods that are used in practice or have shown significant promise and have a body of knowledge that supports statements made in this report. This is a useable tool for professionals, researchers, educators and students

Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

Timber is one of our most precious, versatile, and vulnerable resources, so using it effectively is important. Knowing your material inside and out is the first step to doing just that. Read about the structure of wood itself, from growth rings to its chemical composition. Learn wood's physical and mechanical properties, including everything from elasticity to nuclear radiation. This extensive manual includes a section on stress grading as well as thorough descriptions of which fasteners to use and when. It has information on adhesive bonding, biodeterioration, control of moisture content, preservation, fire safety, specialty treatments, and much more. The Encyclopedia of Wood is an essential resource for builders, architects, engineers, and woodworkers.
