New Nursery School Building in the District Les Sablons, Le Mans, France
This single story 11,840 ft² nursery school accommodates up to 70 children. The building property is also surrounded by playgrounds and other green spaces.

The local political desire was to use sustainable materials for the new building. The district residents voted for a green roof to be included in the project.
The engineering office ARTEMIS INGENIEUR assisted the project management team in the building design phases including preliminary design, final design, project planning, and construction documents. ARTEMIS INGENIEUR designed the structure including the lateral bracing and sizing of the building elements.
The exterior facades consist of timber panel walls. The interior load bearing walls are designed with CLT panels.
The framework includes double glued-laminated tapered beams which supports the green roof and multiple photovoltaic panels.
The structure was analyzed for ULS, SLS, and earthquake (low level of seismicity). The RF-DYNAM Pro add-on module for RFEM was used to perform a modal analysis and generate of equivalent seismic loads.

Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055 Part 4 are referenced.
The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.
The design of structural components at risk of buckling or lateral-torsional buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is compared to the maximal allowable deflection.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads.
Design-relevant parameters such as the stability analysis type, member slendernesses, and limit deflections can be freely adjusted.
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The protocol lacks information on the limit time for the assessment of fire resistance R in the RF-TIMBER Pro add-on module. Can this information be added to the report?
- How can I model a timber-concrete composite floor?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- When performing the fire resistance design with TIMBER Pro, I get the error 10001. How can I fix the error?
- I have selected all available members for design in RF-/TIMBER Pro. Why are tapered members not designed?
- Is it possible to set user-defined values when viewing solid stress results?
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
