Q8.5: Our team is wondering what specific Butterworth Filter parameters will be used to process the raw accelerometer data at the competition? Ex. What order, low/high frequencies will be used to filter the data?

A: A suitable low pass filter to remove noise from the obtained data will be used. The filter is calibrated based on the shake table and the same post processing will be used for all the teams.

Q8.6: We are requesting for the names of the earthquake records associated with the ground motions (GM1 and GM2) and if possible, also the names of the station at which they were recorded.

A: The ground motions are artificial and not based on an actual earthquake event, therefore they do not have a corresponding recording station. The ground motions are based on the geographic location and the structural response of this year’s design challenge.

Q8.4: What are the specifications of the accelerometers to be used? What is their range? What is the sampling rate that will be used at the competition?

A: The teams don’t have to bring their accelerometer. The SDC organizing committee will provide the accelerometer and perform the post-processing based on standard practice.

Q8.3: Under section 8.3/8.4, the rules specify a 1/2 in. diameter rod to be inserted for dead load installation. In the 2022 rules, the length of the rod is specified as 20 in. long, however we were not able to find the length in this years’ rule book. As the tower dimensions are different from 2022 to 2023, we were wondering what this years’ 1/2 in. steel threaded rod length is

A: The rods that will be used in this year’s competition will have the same dimensions as the previous year: 0.5 inch diameter and 12 inch long.

Q8.1: It is stated that there are 2 different weight models specified for 2 different earthquake directions specified in the design guide. These loads are min. and max. values are certain, but the dead load weights to be installed in the mezzanine floors are not clearly expressed. Since we do not want to make any mistakes regarding this, we kindly ask you to indicate how much weight will be applied for the given two directions for different floor levels.

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’.

Q8.2:In the design guide, it is stated that the accelerometer to be placed on the model will be fixed with the help of clamps. Since we could not find any clear information about the weight of the accelerometer and the clamp, we kindly ask you to share the accelerometer and the total clamp weight to be used in order to calculate the maximum displacement and acceleration values of the structural model.

A: Please refer to section 8.3b of the ‘Official rules’.
