Condition Assessment of Timber Structures - Quantifying the Value of Information

摘要

Advanced inspection techniques, non-destructive (NDT) and semi-destructive (SDT) testing methods and structural health monitoring (SHM) are increasingly important for the preservation of both old and new timber structures. However, e.g. the application of SHM within the context of timber structures is not adequately represented in strategic documents. COST Action TU1402 is trying enhance the benefit of SHM by novel utilization of applied decision analysis on how to assess the value of SHM - even before it is implemented. The present paper illustrates how pre-posterior decision analysis can help quantifying the Value of Information (Vol) obtained by the condition assessment of timber structures and thus help select appropriate assessment procedures and subsequent maintenance actions. As a case study a timber exhibition hall in Zagreb, Croatia is investigated in the context of Vol analysis.
