The hybrid design of the building includes a solid timber structure with tapered glulam columns and beams, as well as steel elements such as compression struts, tension members, and stiffening elements hidden in the roof of the main structure.
The entire roof structure consists of repetitive individual structures resembling pear blossoms. Together, these blossom elements form a perfectly shaped architectural unit. Each of the individual structures is supported on five columns with a height of 5 to 7 m (16 to 23 ft).
The bottom of each column is fixed by steel parts and threaded rods glued into glued-laminated timber. The glued-in rods are also used for the moment connections at the Y-shaped joint of the roof frame. The RFEM structural analysis program was used to model the overall structure, check the member cross-sections, and determine the forces for the connection design. In addition, the add-on module RF-STABILITY was used to calculate the global buckling analysis for the flower-shaped structure and the local buckling analysis for the compression struts.
The engineering office JKA, based in Vancouver, Canada, provided the full mass timber consulting services, from preliminary design to the connection design. JKA are experts in mass timber structures, providing their clients with solutions of integrity, simplicity, and style.
