Hotel melt

As the project is located in Bordeaux (seismic zone 2) and is category 3, a modal analysis was necessary to validate the stability of the structure with respect to horizontal seismic forces.

LEGENDRE CONSTRUCTION

Bordeaux, France

The project consists of the construction of an 8-storey hotel + 2 semi-underground levels. The project also includes a cabaret separated by a JD. The ADVANCE modelling only concerns the hotel part.
As the project is located in Bordeaux (seismic zone 2) and is category 3, a modal analysis was necessary to validate the stability of the structure with respect to horizontal seismic forces.

The hotel is located close to a railway line, so an acoustic cut-off is made in the low floor of the ground floor. This vibratory break is achieved by neoprene supports.
The extraordinary feature of the project is therefore the characterisation of the vibratory cut-off in the modal analysis of the project.

The project is designed with a deep foundation system. This foundation system must also be characterised in the response of the building to seismic loads.
The last particularity of the project is that the entire facades of the current floors are connected to the floors by a thermal break system. It is also necessary to characterise this connection system in the response of the building to seismic loads.

 

User benefits:

The advantage of ADVANCE DESIGN for this type of problem is its simplicity in providing information on the stiffnesses in the wires (breaker and neoprene supports).
It also provides rapid extraction of results for point supports and wires, facilitating iterations with the various project partners (Deep Foundations Engineer / Neoprene support supplier, etc.).
A considerable saving of time on the studies of a project like this one especially when one specifies the following figures:
– Number of iterations with neoprene support suppliers: 15.
– Number of neoprene supports to characterise: 89 supports * 3 stiffness values.
Thus, the response time of the design office for the validation of the building once the execution phase was launched was relatively short in order to better satisfy the site requirements.
