[narrator] The main columns
were 16 inches wide with six steel
reinforcing bars
running their length. For earthquake proofing,
a steel spiral wound
beneath the surface, creating a protective
steel mesh. Providing you put enough
spiral around the outside, it can be made to absorb
quite a lot of that shock

[narrator] The main columns were 16 inches wide
00:00:03.767 --> 00:00:06.867
with six steel reinforcing bars running their length.
00:00:08.005 --> 00:00:12.004
For earthquake proofing, a steel spiral wound beneath the surface,
00:00:12.467 --> 00:00:14.007
creating a protective steel mesh.
00:00:15.767 --> 00:00:18.266
Providing you put enough spiral around the outside,
00:00:18.266 --> 00:00:21.266
it can be made to absorb quite a lot of that shock.
