Assessment, Reinforcement and Monitoring of Timber Structures
In recent years, the use of timber in structures has become particularly important, considering that it is the only truly renewable building material and carbon storage. Timber has been used as structural material for centuries and numerous examples demonstrate its durability if properly designed and built and when adequate assessment and monitoring has been applied. The objective of the Action is to increase the acceptance of timber in the design of new structures and in the repair of old buildings by developing and disseminating methods to assess, reinforce and monitor them. The need for assessment, reinforcement and monitoring of timber structures can arise from multiple motivations such as the expiration of the planned lifetime, materials aging, exceptional incidents, and ever more important, a change of use. The Action will benefit from multidisciplinary views of the problems and followed innovative solutions by the involved stakeholders, enable synergies between them and provide an effective way of discussing and disseminating the results from ongoing projects within this research area to the European industry. The Action will increase the confidence of designers, authorities and end-users in the safe, durable and efficient use of timber and consequently increase its use in construction.
In-situ assessment of structural timber
The subjects are in-situ timber (wood, wood materials) structural members and evaluation of their material (physical and mechanical properties) characteristics. The physical properties include the species/species groups, size, orientations, age, moisture contents, density and level of deterioration. The mechanical properties entail strength and elasticity parameters. The target phenomena that will be studied include life expectancy, failure probability and durability of the structure under investigation. The investigations will include both experimental and theoretical studies. The experimental studies will include testing and validation of non-destructive (NDT) and semi-destructive (SDT) methods including case studies where these methods are applied. The theoretical studies will focus on reliability and robustness of the NDT, SDT and their combination. The ND techniques have been used in assessment of timber structures for some time, the SDT are relatively new techniques. New methods are under development and some of the proposed members listed below are actively working on these developments. No reliability assessments of any of these methods and their combinations have been done. The TC will focus on structural applications of timber and aspects such as quality control, product development, composite boards evaluation techniques (unless directly related to in-situ evaluation in structures) will be excluded.
