Stories in the development of tall timber

The development of V2 from the UBC Conceptual Massing, takes a different approach than the CLT based V1. V2 focuses on hybrid construction with timber and concrete as well as taking a balloon framing approach.  This allows the structure to take on a new form architecturally and reach new heights. V2 is 18 stories tall with a stepped terrace layout.

V2 is based on Glulam beams, columns and a central concrete core. Concrete composite timber panels are used as structural flooring members spanning just under 7m. This system allows for an open floor plan that is flexible to many architectural arrangements and works exceptionally well for office spaces. The building is broken into two centres of stiffness with special detailing measures. Additional bracing can be added with steel cross bracing or solid timber panels. This must be compared proportionally to the stiffness of concrete core(s) though. 

This system allows for a repetitive production producing results that are highly adaptable to a variety of design considerations. Modules based on columns run 3 stories tall, dictated by glulam production length. Each module contains:

  • 4 glulam columns
  • 6 glulam beams
  • 6 TCC panels
  • 48 glulam floor joists
  • façade elements to fit
CCT can be produced offsite or poured in larger slabs onsite. Production onsite will increase time, and bring moisture into the construction environment, but it will also add stiffness to the structure. 

V2 needs special attention between the elevator stiffness core and height variation in the rest of the building due to moisture changes. Vertical glulam columns with no cross grain minimize moisture swelling with regard to height, however there will still be specific solutions to mitigate this. A variety of construction approaches could be taken to a system like this for goal oriented efficiencies or multi-criteria optimization. 

Stay tuned for UBC Brock Commons V3 proposal! Things will only get more interesting.
