Diagnostic Stability of Eiffel-Type Metal Framework – Covered Market Hall of Beausoleil

The first step involved a structural diagnosis of the Eiffel-type framework. This required carrying out a reconnaissance campaign, a technical analysis of the existing structures' mechanical strength, identifying any cracks or structural deformities, and establishing the building's structural features. This diagnostic mission notably resulted in a visual diagnostic photo report, a survey of the framework's geometry, and steel sampling for laboratory analysis to determine its nature.

Based on the information collected on-site and the results from lab tests, Axiolis then modeled the structure and examined its behavior according to existing standards.
It was also necessary to ensure that the existing structure's vulnerability to earthquakes was not worsened as part of the renovation work, given the seismic risks in this region.
Strengthening measures and underpinning solutions were required to bring the structure into compliance and to meet the requirements of the renovation program.
In this final phase, Axiolis' added value was in designing reinforcement solutions that take into account the operational constraints and economic considerations of the project.
