Assessment and Monitoring of Historical Timber Construction: Available Tools to Support Decision-Making Processes

== Abstract ==

Timber  structures  represent  a  rich  although  still  underestimated  portion  of 
the historical  built  asset  worldwide  documenting  a  tradition  of  sustainable  practices 
and  craftsmanship.  Assessment  of  their  condition  is  a  fundamental  step  towards  their 
conservation. While some overarching approaches for the assessment of timber structures are 
not dissimilar to  those  used  for  other  types  of  structures,  there  are  some  specific  factors 
affecting timber structures behavior that should be taken into consideration. Such factors are 
especially related to the organic nature of wood, which makes timber’s properties largely 
variable  and  influenced  by  the  environment.  Successful   conservation  of  historical 
timber  structures  requires  combination of many different disciplinary contributions, from 
wood science and technology, to structural engineering, building physics, architecture, art 
history and environmental science, among  others.  This contribution  aims  to  present  an 
overview  of  tools  supporting  decision-making  processes  for  the  assessment  and 
conservation of existing timber structures, including both  methodological  frameworks  and 
technical approaches for data collection and analysis. These tools are reviewed according 
to the scope of the assessment and considering multiple levels  at  which  timber  structures 
are  studied,  at  the  material,  system  and  building  scale.  Additionally,  emerging 
approaches  and  challenges  for  holistic  assessment  of  historical  timber  structures  are 
discussed.
