Designer
This project was conducted on behalf of the ACCOR HOTELS hotel group, consisting of the construction of a JO&JOE Hotel building located in Gentilly in the southern region of Paris, France.
This construction project contains the features as described below:
- Completely concrete basement
- Concrete ground floor
- Second through eighth floors featuring a timber outline with concrete cores
The timber frame structure covers the following elements:
- CLT panels shaping facade walls
- CLT panels shaping interior walls
- LC timber columns
- LVL backing columns
- LC timber beams and lintels
- Steel beams
- Metal angles supporting the openings
- CLT panels shaping the floors
- COFRADAL floor
- Various achievements
The facades are covered with a liner tray-type metal cladding made of thin metal sheet. The use of spacers composed of metal angles, mechanically attached to the plates or the shell supports, allows three-dimensional adjustment.
The slats are fastened to metal rails and the thermal insulation is mechanically ensured thanks to spacers.
Structural Analysis Software
A 3D model of the timber structure and the steel beams was generated to lower the loads on the shell (concrete cores and walls). The rest of the analysis focused on the design check of the CLT floors. The outlining of the layer structure of the CLT panels from the manufacturer (Egoin) and the design of the panels were performed by the RF-LAMINATE module, which integrates a wide range of CLT panel suppliers.
Each floor level is supported on the edges by CLT walls. The floors in the public areas of the hotel are supported by timber and steel beams. The design of the timber beams as well as their fire resistance were carried out with the RF-TIMBER Pro module according to Eurocode 5. The steel beams were designed according to the same principle based on Eurocode 3, relying on the RF-STEEL EC3 module.
