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 their several office and commercial timber projects.Among these is the Palazzo Meridia which is currently the tallest CLT office building in France. The Dlubal customer CBS-Lifteam was responsible for the planning, supply and installation of the timber structure.

Model

The Palazzo Meridia is a 10-story office building, where 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, first floor and two staircases are made of reinforced concrete. A remarkable, open metal facade supports the corridors and allows the plants to climb up 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. In this context, the RF-DYNAM Pro module made it possible to determine the seismic forces and the deformations.

The structural analysis of the CLT elements was carried out with the RF-LAMINATE add-on module. RF-TIMBER Pro was used to dimension the components of the column-beam structure. Since the office building is located in a region prone to earthquakes, (in Nice, earthquake zone 4), a 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.
