Q6.2: In Section 6.1 of the official rules, it states that “Structures will be subjected to 2 scaled and modified ground motions”. How does SDC intend on scaling/modifying ground motions for the shake table that will be used during competition? In order to successfully scale the ground motions to our shake table, we plan to choose between preserving acceleration, preserving impulse experienced, or preserving frequency as given by the power spectral density of the ground motion data. Which of these options will give ground motions that are the most similar to the ones used on the competition shake table?
A: The ground motions posted in the zip file on the competition website are already modified and scaled. These acceleration time histories will be input directly to the shake table.
Q6.1: When will the ground motion data be available? Will it be available before the proposal submission or not? If the ground motion data is available before the proposal submission, wouldn’t it be better if we design the building based on the ground motion data?
Answer: The ground motions will be available on the competition website after the proposal submission. The structure should be designed in accordance with the official rules. A complete analysis and a finalized design of the structure are not necessary for the proposal, so teams shouldn’t need ground motions prior to the proposal submission. Ground motions […]
