The research for this week was centered around the important design aspects of skyscrapers in general. It was important for our group to gain an understanding of the basics of designing a building of this scale.
[2][1] Basics
- Elevator shaft serves as the central core
- There needs to be an adequate elevator to floor ratio allowing for effective movement through the building.
- Make occupants feel comfortable
- Area around the central elevator shaft is fortified by a steel truss braced by diagonal beams
-Some have more than one concrete core
-Lightweight steel skeleton
Balance
-Skyscrapers are so big that the building is expected to have some movement.
-improtant occupants do not notice swaying
-Wind compensation dampers
-Oil hydraulic systems push weights back and forth at the top to control the sway of the building
This basic information provides ideas on what is needed in the design of the Freedom Tower and how we can build off the previous design.
The second piece of the freedom tower is the mid section. The only reason the top part of the freedom tower is not just one solid piece is because the object would not fit in the 3-D printer. This piece has a cylinder on the top just like the previous week but it also has an open socket on the bottom for the base to easily connect to this piece. The dimensions for this piece are as follows: width 3.2in, length 3.2in, height 8.912in. The dimension for the socket on the bottom is a radius of 1.02in located at the center of the bottom face. The dimensions for the inverted triangles will be explained better in the blog 2 weeks from now.
