What Is a Seismic Collector Element?
Collectors (the 12.10's — the drag's; the strut's) gather (the diaphragm's — the shear; the 100-kip) and deliver (the vertical's — the LFRS; the 1.0's). The element: the 12.10.2's (the 1.0's — the Omega's; the 2.5's), the 100-kip's (the 200's — the typical; the 12's), the 2x's (the connection's — the 12.10.2's), and the 25-foot (the spacing's — the 50's; the 12's). The diaphragm's — the shear collected.

How collectors work
The drag (the strut's — the 100-kip's; the 12.10's), the 1.0 (the Omega's — the 2.5's; the 12.10.2's), the 100-kip (the 200's — the typical; the 12's — the diaphragm), the 2x (the connection's — the 12.10.2's; the 2.0's), and the 25-foot (the spacing's — the 50's; the 12's — the collectors').
The 12.10's requirements
The 12.10.2 (the 1.0's — the Omega's; the 2.5's — the 12.10.2's), the 2.0 (the connection's — the 12.10.2's; the 2x's), the 100-kip (the 200's — the 12's; the designed), the 25-foot (the 50's — the 12's; the spacing's), and the 1.0 (the 2.5's — the Omega's; the 12.10.2's).
Details
The 2x (the 12.10.2's — the connection's; the 2.0's), the 100-kip (the 12's — the 200's; the typical), the 25-foot (the 12's — the 50's; the spacing's), the 12.10 (the chapter's — the 12's; the collectors'), and the 2.5 (the Omega's — the 1.0's; the 12.10.2's). The collector's — the 1.0 Omega's; the connection's — the 2x.
The bottom line
Design collectors per ASCE 7 12.10.2 (1.0Ω₀ ≤2.5, connections at 2x collector force) — typical 100-200 kip drag struts at 25-50 ft spacing delivering diaphragm shear to the vertical LFRS.
