Descripción
Physical and mechanical properties of the timber structure of a seven-story building from the end of 18th century, located in Madrid, Spain, were estimated using nondestructive techniques. These consisted of stress wave measurements and probing tests based on needle penetration depth and drilling residue collection, to estimate the modulus of elasticity, modulus of rupture and density. The structure consists on timber framed brick walls and heavy timber floors with mortar filling. For the development of the inspection and data collection a protocol based on previous research works has been defined. First, the wood species were identified as Pinus sylvestris L. or Pinus nigra Arnold ssp. salzmannii (Dunal) Franco and Pinus pinaster Ait. Measurements were taken in five areas of floors and in eight areas of framed walls, distributed between the third and sixth floors. In each of these samples, detailed measurements of at least three pieces were taken. The Time-of-Flight were measured over three distances in each piece, and the punctual measurements for the estimation of density were taken in three cross-sections of the piece. Mean values of density and modulus of elasticity were estimated for each sample. Finally, it was proposed to adopt a mean value for joists and another slightly smaller for pillars. The characteristic value of bending strength was conservatively estimated from the previous values.
