![[FR] CP 001161 | High-Rise Building Le Haut-Bois in Grenoble, France](http://img.youtube.com/vi/0j2t_vhcrOs/mqdefault.jpg)
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.

Model
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.
Structural Analysis
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.
Calculation Tools
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

Considering the Joint Slip in Parametric Timber Cross-Sections
In timber design, beams are often built up of several timber elements. The individual elements can be connected by glue, nails, bolts, or dowels. A glued connection is to be assumed as rigid. In the case of dowel‑type fasteners, the joint is compliant (slip joint) and the cross‑section properties of the connected elements cannot be fully applied.
- How are the signs to be interpreted for the release results of the line release and line hinges?
- How can I create a curved or curved section?
- After the design with RF-/TIMBER Pro, I had a cross-section optimized. Why is the utilization of the optimized cross -section now exceeded?
- Is it possible to design the support pressure or the sleeper pressure in RX-TIMBER?
- Why are the stresses of the 90 ° orientation not displayed in RF-LAMINATE for a layer with the orthotropic direction 90 ° for σb, 90?
- How can I get the member end forces to design the connections?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- How can I run the RX‑TIMBER Frame plugin? I did not find it in the Add-on Modules menu nor in Project Navigator - Data.
- I have a question about the results of the serviceability limit state design: How is the increment of the dead load by the factor 1.8 and the imposed load by 1.48 explained in the result combinations for the SLS design?
- Where can I adjust the effective length lef according to Table 6.1 of Eurocode 5 in the TIMBER Pro add-on module?
