95-meter residential high-rise in hybrid timber as a pilot project in Tanzania
Project
With the 'Burj Zanzibar' pilot project in Tanzania, we aim to establish wood as a sustainable building material for modern housing in Africa. Working with an international, interdisciplinary team, we are focused on creating a local value chain based on renewable resources. Although Tanzania has five times more forest area per capita than Germany, wood is mainly used for energy production and is rarely used in construction. The 'Burj Zanzibar' in Fumba Town will become Africa’s tallest hybrid timber building.
The hybrid timber building will promote the local available wood as the building material of the future and draw attention to a more sustainable construction while offering high living standards.
Structure
‘BURJ Zanzibar’ is planned as a hybrid timber-concrete high-rise. The lateral bracing system of the tower is provided by a central reinforced concrete core extending from the top to the foundations, housing stair and elevator risers. The core’s simple, symmetrical geometry ensures torsional stability and minimizes eccentricities. CLT floors of the residential units form diaphragms at each level, transferring lateral loads to the core. Vertical load is carried by CLT walls and floors, supported by GL24 columns and beams. All vertical load bearing elements continue straight down to the foundation so that complicated and expensive transfers are avoided.
