To begin the structural framing of this building, I first created a grid system. The grid system as shown below is split into two distinct subsections for Level 1 and Level 2. I did this because each floor has its own unique layout and splitting the grid allowed me to better optimize the structural layout for each floor. The grid is shown below. Lines that are part of the Level 1 section are denoted with an “L” for lower. I spaced out the grid lines to try and reduce the need for columns in the large exhibit and lobby spaces. Looking at the building, I tried to split it into less complex rectangular areas where possible. I denoted beam systems to go from north to south to minimize intermediate large support beams.
In an effort to be sustainable, use resources that are readily available, and match the architectural theme, I chose to go with round concrete columns and steel beams. These materials provide high strength and can now be made through recycling and low carbon emitting methods. Walls that did not have large glazing were chosen to be structural walls in an effort to reduce necessary columns. Structural walls were also constructed around the elevator shafts/core.
To compensate for the long stretches between columns, I used beams and columns that can support heavy loads over these distances (~50ft.). I chose W-Wide Flange (W30X108) steal beams between columns and K-Series Bar Joist-Rod Web (18K6) for the beam systems. The beams systems were placed strategically in-plane with the roof for ease of modeling and accuracy. 18” concrete columns were used for the main columns of the building. I implemented structural floors for Level 1 and 2. I further created foundation slabs below columns and structural walls to provide increased support.
The largest challenges that arose while building this structural system were spacing the columns over the large exhibit spaces. I had to carefully plan where to place these as to not intrude on the usage of the room. Another challenge was modeling the structure around the glazing elements to not block views. I had to make some compromises but ultimately arrived at an end product that I am happy with.
I created a collaboration view within Autodesk Construction Cloud to better understand the architectural and structural models working together. This view is shown below:
