The treetop tower consists of a main supporting structure with 16 curved, rotationally symmetric larch glued-laminated timber beams. The upper bracing is provided by steel diagonal members, the lower bracing by steel hollow section crosses. The timber spiral structure is attached to steel hangers and steel cross beams. The calculation was carried out using the second-order analysis and showed a compressive force of 1160 kN and a maximum horizontal deformation of 15.7 cm. Developed by WIEHAG GmbH. WIEHAG Website
