Abstract
The operation of civil engineering structures subjected to thermal
and mechanical loading has led the CEA to examine
temperature-dependent variations in the concrete properties and the
processes affecting the durability of these structures.
A new approach has been undertaken to specify the thermal,
hydric and mechanical history of these structures. This technical
approach is based on three areas of research: material
characterization, modelling to identify weaknesses in the structure
and validation by experimental tests on heavily instrumented
structures subjected to representative loads.
The procedure adopted for long-term interim storage
facilities [1, 2] can also be applied to other domains.
