Since the structure is exposed throughout the building, we carefully selected member shapes and detailed connections to achieve DSK’s vision for the building’s aesthetics. Highlights of the structural design include the following:
- Creative wood framing for a feature Tree Room roof consisting of closely-spaced dimensional-lumber purlins crossing over engineered timber rafters, allows the framing to act as a two-way system
- Engineered lumber combined with strategically located steel members permits long spans and large exterior overhangs of the roof high above the Tree Room gathering space below
- Carefully placed “trees” in the Tree Room constructed from a steel core and clad in lumber taken from actual trees felled on site to make space for the building
- Two types of custom-detailed, built-up steel columns minimize steel sizes, allow for simpler connections between the structure and the enclosure, and avoid the feeling of imposing steel framing
- Complex structural layout with numerous transitions at changes in function or changes in framing direction
- Three different types of lateral-load-resisting systems work in concert to support the design’s structural, functional, and visual requirements
