| The accurate assessment of the mechanical properties of old timber structures is still a great source of conflicts among architects, engineers and constructors. Even nowadays and with the exception of a minor amount of historically important buildings, this situation is commonly used as a justification for the integral replacement of all the timber structural components [1]. This paper presents a case study detailing the procedure followed to assess the mechanical properties of old timber beams made up of ¿pitch pine¿ employed as structural floors in a 19th century building. After many years abandoned, it was decided to transform the building into a public museum. A priori, the assessment of the timber mechanical properties appears to be particularly difficult because there are not any grading rules for old ¿pitch pine¿ beams and even in the case they have existed, several beams had been hidden inside artistic covers or over suspended decorative ceilings. Under these conditions it was planned a two-step inspection. In the first step, the biological degradation of the timber would be assessed employing the resistograph and, during the second step, six load tests would be carried out on individual members in order to assess the mechanical behaviour of the timber beams. All the necessary work was carried out in few days with a reduced budget and the museum was inaugurated in 2007 preserving (with a minimum reinforcement of some elements) all the existing timber floor beams. | |
