 AE 481W/482 Course Reflection

The Search
Senior year thesis begins long before classes start our 5th year. I started my summer working at my internship with Mesen Associates. Throughout the summer I was searching for a thesis building aiming towards building that had a unique look to the facade. I, as well, was looking for a building made of concrete because initially I wanted to work primarily with steel and build my thesis around this conversion of concrete to steel. The first two buildings I found was a 22 story hotel in Portsmouth, VA right along the east coast. This building was interesting where I would have probably focused on the lateral system. The second building was a 12 story office building in northern VA made of a concrete framing system where I would be concentrated on the conversion of concrete to steel. Due to uncontrolling factors these buildings were unattainable and which was quite luckly for me because I was able to find the Executive Tower in downtown DC. Through the aid of Renee Gibbs and Jason Lee I was able to gain the owners premission only a few weeks before the summer was over.

AE 481W: The Proposal
Throughout the semester we had to produce reports for three technical assignments. The first assignments was nothing to grinding. I proformed the proper spot checks to become more familiar with my building. Technical assignment two was probably the most help when it came time to setup a proposal. In Tech 2, I proformed four alternative system: two concrete and two steel. The concretes system were small alteration of the one in place. I studied converting from a flat slab with drop panels to a flat plate to make the building more constructible. I also added post tensioning cables to the flat slab system to reduce the thickness of the slab. As for the steel systems I had open-web joists as my first system as this was system we mostly used at Mesen Associates where I had worked. I also studied a composite deck with W shape girders and beams. In the end, I had narrowed it down to either doing the post tension system vs the steel composited deck. I drew sketches of each and showed them to Dr. Hanagan only a few days before the proposal was due to see if she had any last minute advise to help me make a decision. She approved both plans saying they would both make a good thesis study. She also narrowed the two system down to what would be most beneficial to me, saying I could do the steel system if I wanted to do something I already know well but the post tension would be more valuable to me since I had not nor was taking a prestressing class. She left me with, "if you do decide to do the post tension, don't procastinate." "Oh well I dont think Im procrastinating too bad." "Well you have made up your mind yet and this is due in three days." Later that evening I tossed around the idea of developing a 12th floor for my system and luckly ran into Prof Parfitt up in the thesis labs and discussed a couple of ways to lower the building height. I evently conclude with lowering the building height through an architectural breadth, Mechanical Breadth and my Post Tension Depth Study.

AE 482: The Thesis
My thesis was more or less set up after I turned in my proposal. The second semester was primarily just approving I can accompolish what I stated in the proposal. I talked to Parfitt about the plan to design the new entrance into Retail space 2 and came up with the idea of creating a small inlet with enough room to fit the stairs and wheelchair ramp. After creating a couple of sketches I choose one, created the CAD drawing to go with it and i modelled a 3D rendering in VIZ. For the Mechanical Breadth i discussed the use of a DOAS system per floor with Dr. Mumma to reduce the air flow through the ducts. But on a closer inspection i chose to attempt to try and reroute the duct to distribute the exist air more evenly. By calling out a 2" bulkhead over the corridor i was able to reduce the mechanical ducts by 4" per floor. For the Post Tension Study i initially try to decrease the slab by 3". But after many failed attempts when when running the tendon in the north-south direction i decided to rotate the bundle tendon 90 deg and only reduce the slab by 2".

 

CPEP & Discussion Board Reflection

The CPEP site was very useful throughout the year. It was nice being able to use the template provided and actually work on your thesis project rather than learn how to create a webpage. The discussion boards seemed to be a use resourse however i did not use them myself so this is about all i can say about them.
