Please click on the questions to see the answers!
1. Introduction
A: There are a total of 4 floors designated as retail space: floors f=1, f=2, f=n-1, and f=n. The floor designation is for both towers (i.e., floor f=1 consists of the bottom floor for both towers, even though they are not connected to each other). Figure 9, elevation A-A in the design guide is a helpful visual.
A: The location for the competition will be announced soon, but in the meantime you can go with downtown San Francisco.
A: The building model can be scaled only for render purposes to show any aesthetic features of the building if it would be constructed in real life. However, for the cost and revenue, no scaling is allowed as the FABI is based on the area of the wooden model.
6. Design Proposals and Damping Device Approval Process
A: The damping device is not required to be designed to be removable during the competition. This section is meant to specify that damping devices should not affect the stability of the structure, rather as a supplemental element to assist in energy dissipation. It will be obvious if stability is compromised if damping devices were to be removed from the structure. Hence, in case SDC Chairs determine that the damping devices must be removed, it would benefit teams to design their devices in a way that extraction of the devices would be relatively straightforward and wouldn’t compromise the structural integrity of the tower.
A: The due date of the damping proposal will be announced to the teams soon. It will be on a separate date from the design proposal submission.
7. Structural Model
A: The skybridges need to be centered between the two towers, i.e., they cannot be staggered from each other. This is further clarified in the Design Guide, Section 4, Floor Requirements.
A: The roof plate needs to be touching the two towers and the skybridges. We will accept that there are minor areas where the roof plate will not be touching anything, however, it needs to be centered in the building and touching the skybridge and the two towers. Please click here to see illustrative sketch (not drawn to scale).
A: Curtain walls as non-structural elements should not be in the actual physical model but can be added in the architectural rendering. Furthermore, gusset plates are not curtain walls. Gusset plates are permitted but shall not be in contact with any wall members. A gusset plate shall be in contact with and glued to at least two frame members in contact. Each gusset plate shall fit in a 0.100 in. by 1 in. by 1 in. box. Also, each individual wall member in its final state attached to the model shall fit in a 0.100 in. by 3.000 in. by 11.000 in. box.
A: Refer to Figure 12 in the Design Guide, especially to the top left X bracing orientation for the floor rentable area. For an area to be counted as rentable area, a span from any point perpendicular to a beam bordering the opening has to be 2.5 inches or less.
A: There is no restriction on how to connect the sky bridges to other structural elements as long as you abide by the other rules mentioned in the “Design Guide”. The topmost skybridge has to have two crosswalks.
A: No, If you use the area on the roof of the skybridge, you will use it for your rentable area. So you are not allowed to put any members on the top of the skybridge as the roof is not counted as a rentable area!
8. Strong Ground Motion Testing
A: The floor dead loads are installed at specific floor levels only. The details can be found in section 8.3 of the ‘Official Rules’ and section 5 and 8 of ‘Design Guide’.
A: Please refer to section 8.3b of the ‘Official rules’.
11. Judging and Appeals
A: The teams will be able to work on the first day of the competition until we start the preliminary judging. Roughly the students have until 6 pm of that day to fix any damages that might occur from the transportation process. However, once we start the preliminary judging the students are not allowed to touch the building.
A: Yes, dedicated space with a mailing address will be provided. The details will be provided soon.
A: No, you do not need to have the student chapter officially established. We understand that it takes time to establish the chapter, and you are actively working on getting the approval for an official chapter. We welcome your participation and encourage you to follow up with EERI about your student chapter status.
