About this detail

A trapeze assembly is suspended from an overhead structure by threaded rods with vibration isolators and diagonal 1/2-inch diameter slack aircraft cables for seismic restraint. The trapeze member consists of a steel channel or strut carrying multiple supported pipes, braced by vertical, diagonal, and longitudinal steel angles secured with bolts. Anchor points at the structural deck connect the support rods and slack cables, with vibration isolators modified to include upward limit stops. A companion schedule outlines maximum dead loads, bolt diameters, angle sizes, maximum trapeze spans, trapeze sizes, top connection types, rod diameters, and maximum rod lengths.
