This stadium developed in Brussels was inspired by my favorite sport of all football. It took many months in order to get all of the functionality that I wanted this particular project to have. All of the concrete uses industrial waste to carbon seal them within the structure. All panels use recycled fibers.
Development
The initial shape as seen bellow came about by sculpting various layers about the z axis.
Bellow you can see how the required thickness columns are seen displaced radially based on the requirements of the design algorithm designed. They follow the beams that follow the risers to support them and line up appropriately.
Then it was on to create a sub structure that could hold the panels in place as the panels are offset from the original concrete structure. For that task a Voroni function allows us to create that sub structure perfectly dividing it into the pattern allocated for this design.
Then it was time to place risers on the inside and the rest of the engineering functions as can be seen in the diagram bellow. This included an alternating roof structure the beams for it and a connection between the roof and the façade seams.
It was now time to add individual chairs as that was one of my initial constraints. This was rather easy using at parameters for lines within Dynamo and subdividing the lines to create the desired amount of chairs within the facility. Below you can see the entire code to get an idea of how complex this project is.
The façade came next adding them was easy due to paneling functionality within Revit and Dynamo. I created my own façade panels that open in only one direction but because of the underlying geometry of the building the panels will contort into new directions for the opening in great effect as can be seen below.
Difficulties
First, I had created too many chairs and thus had to reduce the amount of overall chair instances from the original set as seen below. Though this was not difficult.
Second, I ran into the difficulty where once the family instances for the chairs were all placed in the correct location, their directions were all looking at degree 0 so the entire stadium starred at the left or right side. This was such a disappointment thinking how am I going to fix this. Because as you can see I couldn't understand at that moment how to rotate all the chairs to face towards the center of the stadium. I tried rotating all of them within my render engine but that was impossible or would take days. So I left the problem for another day as I could only rotate one or all of them in a series at the begining.
One day I opened a new dynamo screen running the project and came up with a short code that allows the program to gather all instances of the chairs and rotates them the degrees that are required to get the chairs to face towards the middle. Initially I couldn't get it to work but the code was right I just had some unknows such as where does the selection of instances start and it took some time to understand the structure being used and, once I ran through the entire code once more I realized only the initial and lasting angle were the 2 unknowns. then it was on to fix that.
The code above fixed everything and all of the chairs were now facing the right direction (towards the middle of the stadium). Below you can further see on the render how the geometry and BIM creates fantastic renders.
In this last render the tennis court was meant to show how the stadium has modular flooring that can accommodate various sports and other entertainment.
