“…The template is implemented in a database management system (MS Access) according to a tree-like organization [9], which reflects the typical hierarchy in timber structures (i.e., building, primary and secondary systems, units, members and connections (as described in Figure 3). A general description of the inspected object (at the different levels) includes structural type, geometry, historical information, service conditions (Figure 9 -upper panel).…”

“…This tool is based on some of the outcomes of the COST Action FP1101 [7], Working Group 1 "Assessment of Timber Structures", which, through the activity of the Task Group 1 (TG1) "Synthetic methods for the assessment of timber structures" [8]; [9], focused on the development of templates for the inspection of heritage timber roof structures. The first level of assessment concerns the structure as a whole, its three-dimensional geometry and configuration, in order to ascertain if the structural layout is suitable for its load bearing function, with regard to all possible loading condition the structure is exposed to.…”

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.

“…Visual inspection is a fundamental first step for all different scopes and levels of assessment. [6] and [11] present a digital template to collect information during visual inspection, by considering the different hierarchical levels of a timber structure: from the building as a whole, the structural complex and system/s, the timber elements and the connecting joints. Following this multi-scale approach, the template includes a section for damage assessment [11].…”

While the template is designed to be adapted to different construction types, its implementation and initial use have been limited so far only to timber roof systems typical of the Western construction tradition.…”

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.

“…This is testified by several recent studies [5][6][7][8][9][10][11][12][13][14][15][16] dealing with the most common structural types and the robustness assessment of existing timber large span structures. With specific regards to the timber structural roofs and floors of monumental buildings, survey forms have been also implemented within the European project COST Action FP1101 [17,18].…”

The Cartis Form for the Seismic Vulnerability Assessment of Timber Large-Span Structures

et al. 2021

View full text Add to dashboard Cite

Italy is located in a very active seismic zone, and many earthquakes have marked the country, some of them in the recent past. In order to take adequate measures of seismic prevention and protection, in the last decades, the Italian Civil Protection Department (DPC) initiated a survey and introduced a specific form for the quick and/or post-seismic assessment of buildings. This is useful to obtain statistics on the types of structures and their vulnerability and a judgement on the damage, leading to a decision about the possibility of reuse and/or the level of retrofitting to be applied. Those activities have been developed since the beginning of 2000. This task is currently carried out by the Italian DPC-ReLUIS project research, line WP2 on the inventory of building structures, setting up the CARTIS form for any structural type, like masonry, reinforced concrete, precast concrete, steel, and timber structures, the latter being mainly related to large span buildings, extensively used in Italy. In this context, the paper presents the first draft of the CARTIS form for large span timber structures that provides a general description for typical structural schemes, through the singular points commonly considered as seismic structural vulnerabilities. Moreover, the statistics on timber large span structures based on a sample of 10 buildings is presented.
