I selected the Twisting Triangular Mass for the first part of the assignment.

I started by setting the project location to San Francisco at the Transbay Terminal. Then, with the mass in place, I added the levels to divide the mass element into mass floors that can be used to compute the Gross Floor Area of your building.

The parameters to analyze will be the Base Radius and the Middle Radius of the tower. The Base Radius parameter will iterate in 120, 130, and 140, while the mid radius will iterate in 75 and 90 to run the 6 test cases to report.

After the evaluation, the results posted on the excel sheet are the following:

The results in blue are the only combination of parameters that are between the Gross Floor Area range (1,200,000 to 1,500,000 SF).

The proposed tower has a formula assigned for the top Top Radius dimension as follows:

To compare the results, I will iterate the same parameters as in Part 1, but this time, adding more values to create a 12 iteration table of results. The parameters to analyze will be the Base Radius and the Middle Radius of the tower. The Base Radius parameter will iterate in 120, 130, 140, and 150, while the mid radius will iterate in 75, 90, and 105 to run the 12 test cases to report.

The above configuration shows the following results:

The results in blue are the only combination of parameters that are between the Gross Floor Area range (1,200,000 to 1,500,000 SF).
