Options for a tall hybrid building with timber structural systems are investigated as part of a desktop exercise. The proposed commercial building has a concrete podium at the ground level, a central core and structural components along the perimeter leaving the space in between completely column-free. The different structural systems include concrete and concrete-timber hybrid cores in combination with frames, shear walls and braced frames. The building is located in Vancouver, BC, a region with high seismic risk and considerable wind load. Floor vibration requirements are taken into consideration in addition to the gravity and lateral structural requirements. Structural member sizes have been determined and connection details for typical members have been detailed to meet code requirements. The results confirm i) the feasibility of wooden structural systems in tall hybrid buildings and ii) that the design is mostly governed by drift under wind or seismic load.
