Q

What is a mini mill?

A

A process of steel making in which structural steel is produced from scrap steel in electric furnaces. These are miniature only in comparison to traditional mills and produce most structuralist steel for frames of buildings

Q

What is the general process of steelmaking?

A
  1. Molten iron is produced in a blast furnace
  2. oxygen is introduced, blurting out impurities, changing molten iron to molten steel. Any admixtures are added
  3. molten steel is cast into molds in preparation for the ruling mill process
  4. the structural steel shape is made by passing the Bloom’s or slab through heavy rulers a number of times

What happened should the John Hancock buildings glass curtain wall?

A

Curtainwall failure due to adherence of lead solder to reflective coating and telegraphing of solder fatigue cracking into glass through strong bond of solder to reflective coating

144
Q

uHow are aluminum curtainwall millions made

A

A large cylindrical billet of aluminum is heated to a temperature at which the metal flows under pressure but still retains its shape when the pressure is released
the heated billet is placed in the cylinder of a large press where a piston squeezes it under great pressure through a die
the die is a steel plate with a shaped metal orifice that imparts the final profile to the aluminum extrusion
Shapes are produced in long lengths, like steel,
and then cut to specifications.

A

Prestressed

200
Q

What are the steps for pre–tensioning of concrete

A

Stretch the steel pre-stressing strands tightly across the casting bed
concrete is cast around the stretched strands and cured the concrete bonds to the strands
when strands are cut the concrete goes into compression and the beam takes on the camber

The concrete is not allowed to bond to the steel strands during curing

after the concrete has cured the strands are tensioned with a hydraulic jack and anchored to the ends of the beam. If the strands are draped as shown here higher structural efficiency is possible than with straight strands
