Structure and Design
The structural concept of the building with 11 above-ground floors is based on using several types of CLT panels, depending on the floor. That is, the higher the floor, the lower the panel thickness. The cross‑laminated timber walls ensure the stability of the building.
Due to the diaphragm effect of the floors, the horizontal forces caused by seismic activity and wind are transferred by the vertical supporting members to the foundations.
The floors are supported by a glulam column-beam system that does not contribute to the stability of the building. Some of the timber downstand beams are replaced by steel beams. The bottom reinforced concrete part of the structure (ground floor) is very important, as it absorbs the vertical and horizontal loads from the upper floors and transfers them to the pile heads.
For the design of the CLT panels and for seismic analysis, structural analysis software RFEM was used.
