Longitudinal Seismic Bracing Options for CPVC?

5/31/2019

As best I can tell there's no listed bracing method for longitudinal seismic bracing for CPVC. Traditionally we've addressed this by placing a tee with a short pipe stub perpendicular to a main and braced that perpendicular pipe with a "lateral" brace, which acts longitudinally on the main. The downside to this is that it's not concentric to the main, but it's pretty close.

Is there a better way to brace CPVC pipe longitudinally?

For longitudinal bracing for CPVC and to keep the locations of the seismic requirement according to plan we typically use a tee and cap. You can install the brace on an arm over but it must the same size as the main.

Manufactures of engineered composite joists do have seismic details on how to attach the swivel attachment (knuckle). Typically a Tolco fig.909 with an Afcon AF035 Model K fast clamp and 1" steel schedule 40 pipe

Trusses can be quite different and must consult the architectural engineer.
