Goal

• Construct structure modeling World Trade Center
  (WTC) Design
• Focus on the main points of WTC structure such as
  the brackets, trusses, core, and outer walls

3
Processes For Construction

• Drilling
• Gluing
• Riveting
• Sawing
• Milling

4
Inner Core

• The inner core is 4x4x24. Riveted to the
  plexi-glass walls are two pieces of plywood ¼
  apart.
• Twelve brackets are inserted into ¼ space per
  level.
• Core is covered with Aluminum foil and conductive
  paste to distribute heat evenly to above floor.

5
Outer Wall

• Riveted into the plexi-glass sheet 12x12x24
  are two plywood strips 12x24 for each floor.
  
• Between these two strips is a ¼ space where the
  12 brackets are inserted.

6
Brackets

• Shown are the brackets inserted into the space
  between the plywood strips.
• Epoxy is placed on the back side of the brackets
  to hold them in place.
• The groove in the middle of the bracket was
  created using a drimmel tool to mill out a space
  1/8 deep 1/8 wide.

7
Brackets

• Each truss will fit into the groove in the
  bracket.
• Finishing nails were inserted into wood on each
  side of the brackets groove to prevent
  translation of the trusses from side to side.

8
Trusses

• Each truss is 3 1/8x1/8x1.
• There are a total of 16 trusses per floor.
• The trusses are inserted into the groves of the
  brackets.

9
Tiles

• Ceramic tiles are cut into 3 1/8x11 and 3
  1/8x4 pieces.
• Tiles are laid across the trusses for a flat
  stable floor.
• There are a total of three floors
• The tiles represent the live load on the building

10
Lights

• Lights are constructed using disassembled 500
  watt halogen spot lamps and sheet metal.
• The disassembled lights are riveted into a
  fabricated sheet metal housing.
• The lights will be used as heat sources that can
  reach over 200 degrees Celsius.

11
Damage Zone

• On one side of the outer wall and inner core a
  damage zone is cut away using hole saws
• The outer wall damage zone is cut away using a 3
  hole saw.
• The inner core is cut away using 1.5 hole saw

12
Constructed Model

• Finished model is constructed, tiles are
  inserted, and heat sources are installed on each
  side of core.
