“…Indeed the hygroscopic nature of wood can lead to dimensional variations of the elements in service, with possible deformations, disconnections or occurrence of internal stresses due to constrained swelling or shrinkage strains [14], resulting eventually in loss of structural integrity and the development of cracks. Moreover, most physical and mechanical properties of the material are affected by wood MC [15]; [16], and the long-term performance of timber elements, both in terms of load bearing behavior (i.e., creep) [17]; [18]; [19] and durability [20]; [21], can be negatively influenced by prolonged exposure to a humid microclimate. As a note related to the rheological behaviour of wood, it is worth mentioning that traditionally, it was very common to build timber structures using green wood; significant deflections can be therefore found in heritage timber structures, as a result of creep of timbers loaded while green.…”

This paper reviews the official documentation (standards, guidelines and procedures) available for the assessment of heritage timber structures. The subsequent discussion does not catalogue all relevant technical literature. Instead, it intends to convey the state of background knowledge, recommendations and code rules using some illustrative examples. A specific focus is given to visual inspection as a fundamental first step for all different scopes and levels of assessment. The objectives of this review are to: 1) highlight the gaps and limitations in the currently available tools as well as the need for standardization; 2) contribute to the definition of an ontological approach, Highlights • A review of the methodological, normative and operational tools for the assessment of heritage timber structures. • A critical discussion of the gaps and limitations of current assessment tools. • An introduction to a proposed inspection form for heritage timber roofs.

This work is centred on an ancient Italian church. Since 2011, a restoration plan has been undertaken by following sequential phases. The methodological approach to restoration was guided by environmental monitoring campaigns. In particular, two thermo-hygrometric campaigns were carried out during the warm months of the years 2015 and 2016. The first set of measurements was executed during the restoration of facades and roofs, making it possible to reach even areas that are usually difficult to access. The second set was performed to evaluate the indoor thermo-hygrometric conditions following the work of the previous year. This was intended to assess their differences in variability, the influence of the outdoor environment and any real and perceived improvement. Results demonstrate that thermal images helped in identifying both the heat sources causing thermal discomforts and the good thermal capacity of masonries. Concerning the heat index (HI), the church showed an improvement in the trend of malaise perceived by people during the second summer period (∼2°C lower than 2015). Finally, in the last microclimate monitoring, the roof structure no longer acted as an amplifier for daily temperature excursions.

Bu çalıĢmanın amacı, Batı Karadeniz Bölgesinde orman depolarında zarar yapan böcek türlerini teĢhis etmek ve bu bölge için yeni kayıt olan böcek türlerini tespit etmektir. Bu amaçla 7 il ve 21 orman deposuna feromon tuzakları kurulmuĢ ve beklemekte olan odunlar kırıldıktan sonra elde edilen böcekler toplanarak teĢhis edilmiĢtir. ÇalıĢmada 13 böcek türü bölge için yeni kayıt niteliği taĢımaktadır. ÇalıĢma sonucunda odunda zararlı böceklerden Oxypleurus nodieri, Stromatium unicolor, Xylotrechus arvicola, Xylotrechus antilope, Isotomus speciosus, Chalcophora detrita, Buprestis novemmaculata, Lasioderma serricorne, Rhyncolus elongatus, Rhyncolus ater, Helops rossii, Calais parreyssi türleri ve Reticulitermes sp. termit karıncası Batı Karadeniz Bölgesinde ilk defa tespit edilmiĢtir. Bu böcek türlerinin ülkemizde daha önce tespit edildiği yerler de literatür bilgileri ile irdelenmiĢtir.
