A Non Destructive Diagnostic Method on Ancient Timber Structures Some Practical Application Examples
Clara Bertolini, Michele Brunetti, Paola Cavallero, Nicola Macchioni
ABSTRACT The paper, after an examination of some diagnostic techniques on the evaluation of conservation and bearing capacity of timber structures, aims to show a non destructive diagnostic methodology based mostly on a visual mechanical grading of beams, assisted by the data obtained from an electrical moisture meter and from a resistographic drill device. The instrumental data are used for the wooden parts non directly visible, mostly to check eventual decays. Other data detected are deformations under load and disconnection. By knowing wooden species, most important mechanical defects, decays, deformations and moisture content it is possible to g~ the beams, while disconnection allow to make hypotheses on linear and spatial behaviour of structures. The methodology is explicated through practical examples on some ancient timber structures located in northern Italy.
