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 5 columns with a height of 16 to 23 ft.
The bottom of each column is fixed with steel parts, and glued-in rods are employed to make the connection possible. 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 fully model the structure, confirm member sizes, 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 structure and the local buckling analysis for the compression struts.
The engineering firm JKA, located in Vancouver, Canada, provided the full mass timber consulting services, from preliminary design to the critical connection design. JKA are mass timber experts providing their clients with solutions of Integrity, Simplicity, Beauty.
