Structural systems strategy
In the architectural design of my building, I opted for a steel-frame system for both the structural columns and beams, specifically employing W12x26 beams and W10x33 columns. This decision was driven by the need to accommodate the unique features and openings of my building, such as staircases, elevators, and atriums.
To achieve this, I implemented a non-regular grid for the placement of the structural columns. This strategic approach allowed me to model the beams and beam systems around the building’s openings. The irregular grid placement also introduced an interesting visual rhythm to the building’s design, enhancing its overall aesthetic appeal. Additionally, I carefully considered the placement of windows to ensure that no columns obstructed the view.
I chose steel over other materials like wood for several reasons. Steel offers superior strength and durability, making it an ideal choice for structures that need to withstand heavy loads or harsh weather conditions. It is also non-combustible, offering enhanced safety by being fire-resistant. Furthermore, steel is resistant to moisture, reducing the risk of damage from mold or rot, and is 100% recyclable, contributing to the building’s sustainability. While the initial cost may be higher than wood, the long-term maintenance and repair costs are often lower, making steel a cost-effective choice in the long run. Note: I have placed the beams and beam systems of the first level with an offset of -10" to stay below the 10” floor, while I have placed the ones at the second floor without an offset to touch directly the roof.
