Project Presentation
This project in the municipality of Le Boupère consists of two parts.
The first part involved the modernization and extension of the Pierre Menanteau school, creating two new classrooms, a covered playground, and a redesigned playground with an educational garden.
The second part consisted of creating a new multi-purpose hall comprising two areas separated by a removable partition: a small area used for school activities during the day and for social activities in the evening, and a large area used for sports clubs, social activities, events, and local celebrations.
The new buildings have been designed to be energy efficient, using bio-sourced materials (straw, wood fiber) to reduce the carbon footprint and meet today's environmental challenges. The project also includes reusing the old parquet flooring of the town hall.
Structural Design
For this project, the company LCA Construction Bois was commissioned to design and build the timber structures, which represent 130 m³ (28,596 imp gal) and 1,207 m² (12,992 ft²) of timber frame walls, including 355 m² (3,606 ft²) of straw insulation, 1,140 m² (12,271 ft²) of cladding, and 33 exterior timber components made of composite materials and curtain walls.
We are particularly interested in the multi-purpose hall. The largest area, used for sports and other activities, comprises a main structure consisting of four glulam portal frames spanning 18 m (59 ft), with a height of 7 m (23 ft) at the ridge. The gable roof, featuring photovoltaic panels, is supported by asymmetrical tapered beams. Timber frame walls form the two gables of the structure, bracing the frame structure. The gable attached to the small hall has an opening of 9.5 m (31.2 ft), allowing for the installation of the removable partition system.
The smaller space attached to the main hall consists of a timber-framed structure and a glued-laminated timber frame that forms a multiple roof. The roof overhangs provide a space for a raised terrace, and are supported by metal beams of circular cross-section.
Structural Analysis Software
The engineering office of the LCA Construction Bois company carried out the global modeling of the multi-purpose hall using RFEM 5.
The RF-TIMBER Pro add-on module was used to analyze and design the laminated timber structures and framing system in compliance with EN 1995.
As the project is located in Seismic Zone 3, a seismic analysis was carried out using the modules of the RF-DYNAM Pro family.
