This book was released on 2017-08-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deterioration of an in-service wood member may result from a variety of causes during the life of a structure. Periodic inspection of wood used in structures is important for determining the extent of deterioration so that degraded members may be replaced or repaired to avoid structural failure. Inspection professionals use a wide variety of techniques to assess the condition of wood in service. Visual, mechanical probing, and stress wave or ultrasound-based techniques are all used either individually or in combination by inspectors. Although these techniques are based on solid technical information and supporting research, prior to publication of the Wood and Timber Condition Assessment Manual in 2004, no practical, comprehensive manual provided information on inspection of wood in service. The Wood and Condition Assessment Manual was prepared to address this need. The manual was prepared from numerous research studies, inspections, and lectures dealing with assessing the condition of in-service wood and timber. It was intended for inspection professionals. A concerted effort was made to provide clear and concise explanations of various aspects of inspecting in-service wood and timber. To this end, a number of photographs and drawings obtained from actual inspections were included. The 2004 Wood and Timber Condition Assessment Manual proved to be a widely used reference document and a primary technical source for inspection professionals worldwide. User feedback included many positive comments about description of the various inspection tools available and post-fire assessment of structural wood members. Users did express a strong desire to have information on the estimation of allowable design values for in-service wood in future editions.

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.

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.

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.

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.
