Title: Durability assessment of building systems
Author: Lair, J; Le Teno, JF; Boissier, D
Abstract: Assessing the service life of building products is relevant for all building actors (insurers, manufacturers, building owners and architects). Indeed, the knowledge of building products service lives leads to a reduction of maintenance costs and environmental impact, and an improvement of safety. This paper deals with a methodological approach for durability assessment. The major steps are : Research of available durability data and their organization in a graph structure followed by the assessment of belief and plausibility distribution of service life. A Failure Mode and Effects Analysis, including a structural and a functional analysis in order to search all potential failures (weathering factors, product design and setting up). The proposed method is a multi-model and multi-scale approach; multi-model in order to adjust the model with our knowledge and our aim (modelling real life of building, but not a too complex and unusable model), multi-scale to take into account the links between the three geometric scales materials/products/building. Finally, it gives (1) a distribution of nominal service life, for normal weathering processes, with corresponding belief and plausibility degrees, (2) details on the design and setting up problems, on exceptional weathering phenomena, which could lead to a shorter service life.
