“…After modelling the structure, linear static or dynamic analyses can be conducted to investigate the critical elements by comparing the demand with their capacity [14,98,99]. Linear analyses do not show near collapse behavior of structures, and they are mostly used for designing new buildings rather than assessing existing ones.…”

The conservation of heritage structures is pivotal not only due to their cultural or historical importance for nations, but also for understanding their construction techniques as a lesson that can be applied to contemporary structures. Timber is considered to be the oldest organic construction material and is more vulnerable to environmental threats than nonorganic materials such as masonry bricks. In order to assess the structural vulnerability of heritage timber structures subjected to different types of risk, knowledge about their structural systems and configurations, the nature and properties of the materials, and the behavior of the structure when subjected to different risks, is essential for analysts. In order to facilitate the procedure, different assessment methods have been divided into the categories in situ and ex situ, which are applicable for vulnerability assessments at the element and full-scale level of a case study. An existing methodology for structural vulnerability assessments and conservation of heritage timber buildings is reviewed and a new methodology is proposed.

Historical scarf and splice carpentry joints: state of the art

This paper summarises the current state of knowledge related to scarf and splice carpentry joints in flexural elements, also providing some examples of tensile joints. Descriptions and characteristics of these types of joints found in historical buildings are presented. In addition, issues related to forming carpentry joints in historic and heritage structures are discussed. Next, analyses and studies of flexural elements as well as selected examples of tensile joints described in the literature are presented. It is worth noting that authors of vast majority of the publications cited draw attention to the need for further research in this area. They acknowledge that existing descriptions are incomplete and insufficient for bringing about precise understanding and correct description of the static behaviour of these joints. Knowledge about designing and assessing static behaviour of existing carpentry joints is an important issue and is necessary to properly design and strengthen existing joints in historical timber structures.

“…The technology used in this investigation is that of stress waves, a non-destructive method which has proved its efficiency for the mechanical characterization of structural elements of wood (Li et al, 2015;Dahle et al, 2016;Kloiber et al, 2016;Chen and Guo, 2017). This focus is complementary to other techniques and methods to assure the structural reliability of wood edifications with historical and cultural value (Machado area of intervention et al, 2011;Kránitz et al, 2014;Arangjelovski et al, 2015;Feio and Machado, 2015;Henriques and Neves, 2015;Kloiber et al, 2015;Sousa et al, 2015;Zhang et al, 2015;Cavalli et al, 2016a;Cavalli et al, 2016b;Milch et al, 2016;Sousa et al, 2017;Barozzi et al, 2018;Walsh-Korb and Avérous. 2018).…”

<p><strong>Abstract.</strong> In the ceiling framework of the capitular hall of the Cathedral of Morelia, the overall state of the beams of the ceiling framework of the capitular hall of the Cathedral of Morelia was diagnosed as deplorable, for which a replacement was put underway for more recently sawed beams. The focus of this investigation was to determine the humidity content of the wood, its density, the wave velocity, the dynamic modulus and the quality factor of a sample of five new beams. These parameters were compared to the medium of five old beams. For the density, wave velocity, dynamic modulus and rigidness, there were no differences found between the old and new beams. The results suggest that the mechanical and physical properties of the new wood beams are equivalent to those of the older ones. Consequently, the strategy of substituting old and deteriorated wood beams for recently sawed ones was successful and complies with the requirements of the International Council of Monuments and Sites as referred to in the principles for the preservation of historical wooden structures.</p>
