The Silva Tower is an 18-storey, 50-meter high wood-concrete hybrid office building to be built soon in Bordeaux, France. The tower will be built by a team led by French developer Kaufman & Broad, according to the design by local architect firms Art & Build and Studio Bellecour and EGIS Consulting Engineers. This building will have a concrete core, CLT floors and glulam columns, beams and bracing.
On September 15, 2017, as a part of the WoodRise Congress, a technical workshop will be held at FCBA laboratory during which a shaking table test will be conducted on a 1/3-scale model of the structural system used in the Silva Tower. FPInnovations’ researcher Marjan Popovski will be one of the participants to this seismic testing.
The 3-storey building model will be subjected to an earthquake motion as per the European Seismic Design Code (Eurocode 8) requirements, with duration of 30 seconds. The model was scaled down from the original using the similitude laws according to the European Wood Design Code and has unsymmetrical stiffness and mass properties (see figure below).
The results of the test are expected to quantify the structural system performance under earthquake motions. In addition, the results will be able to show the accuracy and applicability of the similitude laws that were used to design the model. The testing will also be an opportunity to showcase the latest advances in tall building design and with respect to seismic performance.
Registrations to the WoodRise congress are currently open. To learn more about seismic performance or the shaking table tests, please contact Marjan Popovski, Principal Scientist of FPInnovations’ Advanced Building Systems group.
