| Abstract |
Wood is very present in the structures of old buildings and real estate with historical value. Yet, as a biodegradable material, it is highly vulnerable to adverse environmental conditions, such as permanent high humidity and attacks by xylophages. Furthermore, being a natural material, wood has great potential for low-carbon building within a circular economy. To preserve historical wooden structures, periodic inspections, preferably non-destructive or minimally invasive, are needed. Inspection may involve visual or resistographic testing techniques. However, both of these methods are time consuming and inaccurate. In this work, the joint use of techniques is proposed, in order to make multi-feature decisions about the repair or replacement of elements. The acoustic emission technique is proposed to determine active xylophages, the elastic wave technique to determine the dynamic elastic modulus and the resistance class, and finite element numerical modelling to determine the state of deformation and structural capacity. An old beam floor from a historic building in the center of Granada, Spain, was used as a practical case. The results demonstrate the effectiveness of a multi-analysis, instead of a single analysis, in arriving at correct decision making. |
