As used here, a “run” is considered to be any straight section of pipe or duct between bends, … NFPA 13 Seismic Bracing Requirements: Cable Sway BracesConversely, 4-way braces on risers can also provide lateral and longitudinal bracing for horizontal pipe (A. Remember, any time that a brace does double duty, its ZOI is larger and it has to be able to bear the added seismic loads. Branch line restraint. Branch lines, except as we discussed previously, do not require bracing.

KINETICS™ Pipe & Duct Seismic Application Manual

Seismic restraints for pipe and duct are generally separated into to two categories. 1. Transverse Seismic Restraints: These act to keep the pipe or duct from swinging side-to-side. They are normally placed so that they act perpendicular, at right angles, to the pipe or duct, as shown in Figure Seismic Bracing Systems - unistrutohio.comIf necessary, seismic force can be recalculated with braces on every trapeze (see figure 2).
