Radiography,operties of wood and difference in attenuation of different material, the radiography is relatively easily applicable to timber. Parameters such as energy level, time of exposure and distance between the source, object and imaging plate permit identification of early and late wood. Quantitative radi

Core-Drilling,Small core tests are correlated with the standard small-clear specimen tests to evaluate compressive strength and modulus of elasticity. Cores are smaller than natural defects such as knots and can be plugged after testing. This is a local method that gives localized information about the mechanical

Shear Test of Glue Lines,l value and are used to make inferences on the member strength. Since the quality of the glue line can vary significantly within and between members, multiple samples must be taken to get reliable global estimations of a member’s properties. In addition to the shear strength, the percentage wood fai

Moisture Measurement,hods using relationship between some physical quantities such as electrical resistance and MC are frequently used. Such methods usually require calibrations for various species, temperature corrections and are direction dependent.Direct (weight method) method will give accurate moisture content meas

Species Identification, the species is basic information for any analysis on wooden artefacts. Specifically for in situ timber structure diagnosis, the determination of the species is crucial for the correct determination of the structural performances of each element. The procedure for the identification of the species p

Dendrochronology,r the reconstruction of the history of an ancient architecture and the comprehension of its evolution. The results of these investigations are of great value not only for historical studies but also for preservation, restoration and consolidation purposes of historic buildings. The paper explains th
