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.

Book Synopsis Inspection of Timber Bridge Longitudinal Decks with Ground Penetrating Radar by : Brian K. Brashaw
Download or read book Inspection of Timber Bridge Longitudinal Decks with Ground Penetrating Radar written by Brian K. Brashaw and published by . This book was released on 2014 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced nondestructive inspection techniques like stress wave timing and resistance microdrilling have been used to successfully inspection timber bridges, but it is most effective on girder style bridges. There is a noted need to develop additional inspection techniques for longitudinal deck/slab timber bridges, which comprise about 20% of the national bridge inventory. One technique that holds potential is ground penetrating radar, a recognized nondestructive testing technique that has been used effectively for many different environmental and transportation applications. It has been utilized successfully to identify buried objects, internal defects and material changes. The objective of this research was to assess the potential for using GPR to identify and assess simulated deterioration in longitudinal timber deck timber bridges. GPR scans were completed in the longitudinal and transverse directions of a screw laminated timber bridge deck before and after a bituminous layer was added to assess embedded defects that simulated voids, decay, insect damage and horizontal shear splitting. Assessment of the GPR wave energy signal was completed using visualization software that was provided with the commercial GPR unit used for the testing. The radar signal was analyzed in both the longitudinal direction (antenna front to back) and the transverse direction (antenna side to side). Interpretation of the radar signals allowed for the identification of various internal defects present in the deck. Based on the results, GPR has the potential to identify internal defects in timber bridge decks before and after a bituminous layer was added. Large, rectangular void defects (at least 6‐ by 12‐ by 5 in. (15.2‐ by 30.4‐ by 12.7 cm)) that were hollow, filled with foam, or filled with sawdust/adhesive were most easily identified under all scanning conditions. The addition of a bituminous layer, common to slab bridge construction, damped the signal response and made it more difficult to identify defects. Several smaller defects that were found in the deck without a bituminous layer were not identified in scanning completed after the bituminous layer was added.
Book Synopsis Inspection and Monitoring Techniques for Bridges and Civil Structures by : G Fu
Download or read book Inspection and Monitoring Techniques for Bridges and Civil Structures written by G Fu and published by Elsevier. This book was released on 2005-09-20 with total page 283 pages. 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

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.
