Title: Chapter 9; Inspection of Timber Structures Using Stress Wave Timing Nondestructive Evaluation Tools

Source: Nondestructive Evaluation of Wood

Author(s)Pellerin, Roy E.; Ross, Robert J.

Publication Year: 2002  View PDF »

Category: Book Chapter

Abstract: The purpose of this chapter is to provide guidelines on the application and use of the stress wave timing inspection method in locating and defining areas of decay in timber structures. Practical procedures for field testing,workable forms for gathering evaluation data, and guidelines for interpreting data are provided. This information was derived from research that quantified the ability of stress wave timers to detect decay in wood, from laboratory and field studies of deteriorated timber bridges, and most importantlyfrom the experience of timber bridge inspectors familiar with the use of these devices. Properties of wood and important aspects of wood deterioration are also reviewed to provide those who are unfamiliar with wood the basic information necessary to detect decay. These guidelines are intended for inspectors. Explanations are given of the operation and use of stress wave equipment for the nondestrictive testing of timber structures.
