ASTM WK81339

Revision of E580/E580M-20 Standard Practice for Installation of Ceiling Suspension Systems for Acoustical Tile and Lay-in Panels in Areas Subject to Earthquake Ground Motions


"ASTM E580 5.2 Lateral Force Bracing," requires that lateral force bracing members shall be spaced a minimum of 6in. from all horizontal piping or duct work. This requirement is very restrictive and at times, impossible to achieve.
The task group assigned to this Work Item will investigate the history of the requirement, investigate the potential for reducing the minimum clearance, and/or investigate an alternative clearance requirement for rigid bracing.
