“strand”—an assembly of wires wound around a central core. Picture 2 is a Z-lock
cable, composed of Z-shaped cold-drawn or cold-rolled wires at the perimeter of the
strand which lock together to “seal” the strand. Picture 3 is a wire “rope”—an
assembly of multiple strands. Image from Pfeifer Catalog, 2000.
Triple-tube jet grouting beneath the mast foundations
will minimize long-term settlements

11. The 10-story-tall masts are composed of three 18”-
diameter steel hollow structural sections (HSS)
arranged in a triangular, tapering form, and tied
together with 12.75” HSS
Pinned-base detail at masts.

13. • The use of multi-level splayed cables allowed the structural roof members to form
a thin and uniformly curved roof plane only 33” deep.
• The curved shallow members support a 7-1/2” long-span metal roof deck that
spans 25’ between the roof girders.
• The W33x169 girders are cold-bent to shape about their strong axis with reverse
curves to multiple radii, and are suspended over the 160’ spans.
