Step 1 - Generative Design Framework
Step 2 - Generative Design Study
For the structural efficiency study, I decided to create a very simple structural framing model with only columns and beams. To do this, I created a 3D grid of curves and then assigned Revit grids and elevations to each. Then I created steel framing elements along these curves and split them up at each elevation and gridline. While I created four sliders for the max height of the building, floor height, building length, and distance between gridlines, only two (max height of the building and building length) were used as input parameters for the generative study. The outputs calculated were total floor area (by calculating the building dimensions times number of floors), and total length of structural framing.
Step 3 - Generative Design Study Results
The parallel coordinates graph shows that at larger values of max building height and building length., the total length of framing is highest and total floor space is relatively evenly distributed. However, at the same max height and when building length drops below 80, the total length of framing drops drastically while total floor space remains evenly distributed. As the max height of building and building length decrease, the total length of framing and total floor space also decrease. From the graph, it seems like max height of building is the most indicative of the output results, while building length varies it slightly less.
