Design memo of 300 to 400 words: which system and why, where the grid fought your architecture, what you changed in the architectural model.
Please paste your design memo here…
For my eight-story mixed-use building, I decided to use a combination of concrete and timber. The first three floors use concrete columns and beams, while the upper five floors use timber. I chose this system because concrete provides a strong base for the building, especially for the lower floors, while timber is lighter and reduces the overall weight of the upper structure. I also wanted to try combining two different materials rather than using the same structural system throughout the building.
I started by placing the structural grids based on my architectural model. Since my building has an L-shaped layout, I tried to keep the grid as regular as possible while following the shape of the building. Most columns could be placed along the grid intersections, but some locations were more challenging, especially near the inner corner of the L-shape and around the stair and elevator areas. I had to think about where the columns and beams would go without interfering too much with the existing architectural layout.
For the structural model, I used concrete columns and beams for the podium and timber columns and beams for the upper floors. I also added concrete shear walls around the stair and elevator cores, extending from the ground floor to the roof. For the foundations, I used isolated footings under the columns and wall footings below the shear walls. One issue I noticed was that some isolated footings overlapped with the wall footings near the cores, which would need to be reviewed in the next design stage.
After comparing the structural and architectural models, I found several areas that would need adjustments. Some architectural walls and openings may need to be coordinated with the structural columns and beams, particularly around circulation areas. The floor openings also need to match the stair and elevator locations. I have not resolved every clash yet, but the coordination process helped me identify which parts of the architectural model would need to change.
This assignment made me realize that a structural grid cannot always be added directly to an architectural design without affecting it. Even though I tried to keep my original layout, some adjustments are necessary to make the structural system work.
