The recent trend in high-rise construction is clearly dominated by timber as the most ecological and environmentally-friendly material. The project promoter Nexity Resolutely is committed to constructive building solutions with a reduced carbon footprint through various labels and certifications included in its several office and commercial timber projects.Among these is the Palazzo Meridia, which is currently the tallest CLT office building in France. Dlubal customer CBS-Lifteam was responsible for the planning, supply, and installation of the timber structure.

Model
Palazzo Meridia is a 10-story office building, of which 9 stories are constructed with timber. With a total height of 115 ft, its ground area is 181 ft long and 56 ft wide. The basement, which accommodates 31 parking spaces, the ground floor and two staircases, is made of reinforced concrete. A remarkable, open metal facade supports the corridors and allows the plants to climb the facade.
Calculation and Modeling
The concrete staircases act as bracing for the entire timber-frame structure consisting of visible glulam beams and CLT facade elements. Large CLT panels with dimensions of 11 ft x 56 ft and 9 ft x 56 ft were used for the facade walls and floors to speed up assembly. The building construction was reduced to 5 months, saving a total of 10 days per story.For comparable results with the reinforced concrete design carried out by a partner engineering office, CBS-Lifteam created a multi-material timber and concrete model including all structure stiffnesses. The Dlubal Software RF-DYNAM Pro add-on module was used to determine seismic effects and deformations.
The structural analysis of the CLT elements was carried out with the RF-LAMINATE add-on module. RF-TIMBER Pro designed and dimensioned the timber frame structure. Since the office building is located in a region prone to earthquakes (in Nice, earthquake zone 4), seismic analysis was considered, assuming the horizontal forces would be transmitted by the CLT floors acting as diaphragms to the concrete staircases. The timber facades would not contribute additional bracing to the structure.

Modal Analysis in RFEM 6 Using a Practical Example
Modal analysis is the starting point for the dynamic analysis of structural systems. This article shows you a summary of how to perform a modal analysis in RFEM 6.

Timber Design | Strength and Stability | Input
The structural system is entered and the internal forces are calculated in the programs RFEM and RSTAB. The program provides access to the extensive material and cross-section libraries.
Timber Design is completely integrated into the main programs and automatically takes into account the structure and the available calculation results. Further entries for the timber design, such as effective lengths, cross-section reductions, or design parameters, are assigned to the objects to be designed. It is possible to select the elements graphically by using the [Select] function.

The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- In RFEM 6, is it possible to display a graphic with the distribution of the required reinforcement in the DIN A0 format?
- How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- Where can I find the graphical results of punching shear in the concrete design? Especially the distribution of shear forces at the critical perimeter or the punching loads.
- Is it possible to display the reinforcement description in RFEM 6?
-
I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet in RFEM 6. How should I proceed?
- Where can find the option to hide the defined types (for example, design supports or effective lengths)?
- How do I create a user-defined Design Situation with my own chosen load combinations?
- How can I neglect torsion in the steel and timber design?
- Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
