My form is starting to take shape in CAD. Here are my preliminary building sections. Both are cut thru the center of my building, top one looking at the seating area, bottom one looking toward the main entrance (lobby area). I have changed up my structure a bit, instead of being all concrete I left the top portion and outer edge concrete and switched to space frame the for the portion on the interior of my building. I think it will be more pleasing to the eye and seem less bulky. These sections also help show how the roof is going to be accessible for mountain bikes and such. The thick black areas are where I actually cut the building, lighter lines are beyond and really light line are far beyond. If you have any other questions leave me a comment and I will try to answer it.

I laser cut a larger scale model to start playing with green roof design as well as main entry features. I am also coming up with options for my clerestory windows to keep them operable for natural day lighting as well as protecting them from hail and high winds. More photos to come... The structure I am looking at is the arch supporting the weight all the way to the ground. This is the easiest way to allow access to the roof by bike or foot. The center oval area would be a giant opaque skylight allowing the entire track to be day lit without creating hot spots or shadows on either the track or spectator seating area. The idea of this is to do a green roof over the structure so it would look like a giant grassy hill. Structure #1Very symmetrical building with 4 main small cutouts/entrances. I was thinking of using each one as a gate to that particular sport (track, cyclocross, mountain, crit) so that entrance could act as a meeting/waiting point for people entering/leaving the facility. Structure #2Same as above but with larger openings and more N/S/E/W opening configuration. This allows for more exterior glass which would help it to be recognized as a building and not a giant hill from I-35 and the boathouse district across the river. Structure #3This option has larger cutouts at the main entrance (left side) and smaller ones around the rest of the building. In this option I plan to stop the exterior wall at the column row this allowing the rest of the space to be covered exterior with the smaller circles acting as protected sitting/meeting areas so you can watch the action at the river as well as people riding around the site and on top of the building. This option is an evolution of the above structure system as well as my favorite of the 3. It still allows access to the roof (mainly on the back side) as well as creating stunning views under the green roof at the building itself. Moving the exterior wall inside the green roof allows me to use more glass and create better views around the area. Per my committee members comments I am going to start studying and building 3 structural models to help figure out what system would be best suited for my building. Below I listed the 3 main "natural disaster" features that I will have to base my designs on since these are relevant to the OKC area. 1. Wind Loads 2. Tornado 3. Earthquake I will also have to keep in mind span distances of such structural systems since I am wanting to keep the track as open as possible and free of columns interfering with sight lines. The images below are of the first structural system that fits my above criteria. The Arched or Domed roof will allow me to span greater distance with fewer materials as long as I buttress the exterior walls and allow the weight the be distributed into the earth. The dome also fulfills a second idea I had in mind as to allowing the building to apart of the outdoor cycling design. With Oklahoma being so flat (especially on my site) trying to integrate a mountain bike facility is quite challenging. Being able to have a green roof we are able to create our own hills and valleys on top of our buildings would be ideal and would keep up from having to import dirt and such from around the area. It will also help with energy needs in the summer since the earth is such a good insulator. I will start pulling parts from the images below and start modeling the structural system for my building. |
