This report is the final form of the deliverable D5.2; in this document are reported the results obtained from a part of all activities provided within the Work Package 5 of the SMooHS project. Results derived from laboratory and on-site testing activities are presented in separated parts of the D5.2 in order to provide the end user specific documents focused on macro-themes recognized of great interest. The Task WP5.3, devoted to the laboratory activities for the characterization of the main construction materials to be found in historic buildings, after the parts dedicated to brick masonry and stone masonry (D5.2 part 1 and part 2 respectively), is here concluded with the section on timber elements. Spruce beams of more than 150-year of age, salvaged from an intervention on an ancient Italian palace, were available in the laboratory of WP5 partner UNIBO, University of Bologna. These have allowed testing the effectiveness of Non Destructive Testing (NDT) in characterising already aged material. This is a notably important aspect since, as it is well known, timber is a natural construction material and it modifies its micro-structure when undergone to ageing. Different investigation techniques (for details on these, see D5.1 part 1) have been applied with the aims of: - characterizing the sections of timber elements with regards to knots, splits, decayed portions, and moisture content, - mechanically characterizing the material in terms of its stiffness or modulus of elasticity (MoE).

Abstract
This report is the final form of the deliverable D5.2; in this document are reported the results obtained from a part of all activities provided within the Work Package 5 of the SMooHS project. Results derived from laboratory and on-site testing activities are presented in separated parts of the D5.2 in order to provide the end user specific documents focused on macro-themes recognized of great interest. The Task WP5.3, devoted to the laboratory activities for the characterization of the main construction materials to be found in historic buildings, after the parts dedicated to brick masonry and stone masonry (D5.2 part 1 and part 2 respectively), is here concluded with the section on timber elements. Spruce beams of more than 150-year of age, salvaged from an intervention on an ancient Italian palace, were available in the laboratory of WP5 partner UNIBO, University of Bologna. These have allowed testing the effectiveness of Non Destructive Testing (NDT) in characterising already aged material. This is a notably important aspect since, as it is well known, timber is a natural construction material and it modifies its micro-structure when undergone to ageing. Different investigation techniques (for details on these, see D5.1 part 1) have been applied with the aims of: - characterizing the sections of timber elements with regards to knots, splits, decayed portions, and moisture content, - mechanically characterizing the material in terms of its stiffness or modulus of elasticity (MoE).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
