Download or read book Nondestructive Evaluation of Wood written by Forest Service (U S ) and published by Government Printing Office. This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-04-02 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines are designed for decision makers (selection, country commissioners, city planners, preservation officers, contractors, rehabilitation engineers, etc.) to understand the components that are used to make effective decisions about how and when to repair a covered bridge, such as structural integrity, engineering analyses, condition assessments, how to support the bridge during repairs, and more. There are numerous types of covered bridges and ensuring public safety during repairs is a paramount issue for future generations to enjoy.

This book was released on 2015-06-26 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covered timber bridges are historic structures with unique aesthetic value. To preserve this value and maintain bridges in service, robust evaluation of their performance and safety is necessary. The strength of the timber found in covered bridges can vary considerably, not only because of age and condition, but also because of species and grade. For the practicing engineer or inspector evaluating a covered bridge, design values for existing wood members must be determined with as much accuracy as possible by account-ing for bridge-specific conditions. The current practice is to assign wood values for strength and moduli from existing specifications without specific reference to timber species, condition, or grade, which can result in an inaccurate assess-ment of the structure. This manual provides a walk-through for basic wood identification, inspection, condition assess-ment, field grading, and design value estimation for wood in covered bridges.

Available in PDF, EPUB and Kindle. Book excerpt: The safety, maintenance and repair of bridges and buildings depend on effective inspection and monitoring techniques. These methods need to be able to identify problems often hidden within structures before they become serious. This important collection reviews key techniques and their applications to bridges, buildings and other civil structures.The first group of chapters reviews ways of testing corrosion in concrete components. Given their continuing importance and vulnerability to decay, the next series of chapters describes ways of testing wood components within civil structures. A final group of chapters looks at visual and acoustic techniques and their use to assess bridges in particular.Inspection and monitoring techniques for bridges and civil structures is an invaluable reference for civil engineers involved in safety inspection, maintenance and repair of bridges and civil structures. - Reviews key inspection and monitoring techniques and their applications to bridges, building and other civil structures - Edited by a leading authority in the field
Download or read book Nondestructive Testing Technique to Quantify Deterioration from Marine Borer Attack in Sitka Spruce and Western Hemlock Logs written by Robert Jon Ross and published by . This book was released on 2014 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress-wave nondestructive evaluation (NDE) techniques are used widely in the forest products industry--from the grading of wood veneer to inspection of timber structures. Inspection professionals frequently use stress-wave NDE techniques to locate internal voids and decayed or deteriorated areas in large timbers. Although these techniques have proven useful, little information exists concerning the relationship between stress-wave parameters and deterioration observed as a consequence of marine borer attack. In this pilot test, we examined the relationship between stress-wave transmission time and the quality of wood in Sitka spruce and western hemlock logs that had varying degrees of deterioration as a consequence of attack from marine borers. Stress-wave transmission time, perpendicular to grain, was measured at several locations on each log. The logs were then sawn into lumber, which was then visually evaluated. A relationship was observed between stress-wave transmission time and deterioration of the logs and the yield of lumber from the logs.
Download or read book Wood Protection and Preservation written by Christian Brischke and published by MDPI. This book was released on 2020-12-10 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is an advantageous building material in many respects, but it is biodegradable and therefore requires protection when used in highly hazardous applications. This Special Issue comprises 19 papers by authors from 14 countries in Asia, North America and Europe. They represent a wide range of aspects related to wood protection and wood preservation, and give timely examples of research activities that can be observed around the globe. Several authors reported on the processes of thermal modification and different chemical wood modification techniques, which are among the latest alternative wood protection methods without the use of biocides. New preservatives and assessment methods of preservative-treated wood products are presented, as well as studies on the natural durability of wood, fire-retardant treated wood, the effect of concrete on wood durability and different novel surface modification techniques using plasma. In addition to biological durability, the mechanical properties, moisture performance, bonding properties, weathering stability and the corrosiveness of differently treated wood are investigated and reported within this Special Issue. Examples of research on fungal biology, service life planning with wood and test methodology are also included and complete the Special Issue.

This book was released on 2012-12-13 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT-- OVERSTOCK SALE -- Significantly reduced list price Wood preservatives are generally grouped into two categories: preservatives used for in-place field (remedial)treatment and preservatives used for pressure treatments.A limitation of in-place treatments is that they cannot beforced deeply into the wood under pressure. However, theycan be applied into the center of large wooden membersvia treatment holes. These preservatives may be availableas liquids, rods, or pastes. Pressure-treated wood has muchdeeper and more uniform preservative penetration thanwood treated with other methods. The type of pressuretreated wood is often dependent on the requirements of thespecific application. To guide selection of pressure-treatedwood, the American Wood Protection Association developedUse Category System standards. Other preservative characteristics, such as color, odor, and surface oiliness may alsobe relevant. Guidelines for selection and application of fieldtreatments and for selection and specification of pressure-treated wood are provided in this document.
