High-Rise Building Le Haut-Bois in Grenoble, France
Two 9 and 6-story residential buildings which include 56 units in total, are the first in France to be certified passive at the height of 9 stories. They are located in seismic zone 4 in the heart of Grenoble’s Flaubert eco-neighborhood. The buildings, constructed with 52,972 ft3 of zinc-coated wood, are both an architectural masterpiece and an innovative achievement to inspire housing sustainability for the next decade.

Extensive CLT panel knowledge, calculation methods, and manufacturing techniques has allowed for easier design and construction of tall wood buildings today.
The residential building Haut-Bois in Grenoble is one of the first CLT building projects in France reaching a height of 99 ft. The total floor space is approximately 50590 ft².
The 9-story building structural concept is based on using optimized CLT panels on corresponding story heights. Therefore, the panel thicknesses decrease as the building height increases. The exterior and inner load-bearing walls provide stability to the building.
The floor diaphragms transfer the lateral seismic forces (zone 4) and wind loads to the vertical supports and eventually down to the foundations. The floors are supported by a metal and glued-laminated timber post-beam system, which does not contribute to the stability of the building.
The reinforced concrete floor slabs are significant in the design as they transfer the upper stories’ vertical and horizontal loads to the foundations.
The CLT panel and seismic analysis were carried out with Dlubal Software’s RFEM.
The following programs were used for the structural analysis:
- Structural FEA program RFEM
- The RF-DYNAM Pro module for seismic analysis
- The RF-LAMINATE module for the calculation of CLT panels and laminate surfaces

Arbitrary distributions of concentrated loads often occur in the load definition of beam structures.

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.
- How can I model a timber-concrete composite floor?
- I have a model of a timber building, which I have transferred from Scia Engineer and adapted it into the RFEM program. The models should be the same; however, it can only be calculated in Scia Engineer while RFEM reports singularity. How do I edit the model to analyze it in RFEM?
- 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?
- 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?
- Is it possible to set user-defined values when viewing solid stress results?
- I have selected all available members for design in RF-/TIMBER Pro. Why are tapered members not designed?
- When performing the fire resistance design with TIMBER Pro, I get the error 10001. How can I fix the error?
