Mason Seismic Restraint Guidelines.pdf - MASON Notes on Seismic Bracing:1. These guidelines list installations, which may be exempt from bracing. However, the engineer of record shall be responsible for determining whether to allow the exceptions. 2. Each straight pipe, duct or electrical run with two or more supports requires a minimum of two transverse braces (perpendicular to the run).
Utilize our pre-approved seismic engineering guidelines to assist with your next project design, bracing layout, and submittal package for piping, ducts, conduits, cable trays and other systems. TOLCO seismic engineers helped to develop OPM testing methods with OSHPD and is the only pre-approval to include cable tray hold down clamps.

Technical Seismic Technical Guide Document Hanger Wire Attachment Code Requirements 1 The International Building Code (IBC) defines the requirement for hanger wire and their supports and attachment methods. However, there are exceptions and the application of hanger wires in a seismic design category can meet code requirements in different ways.Seismic Bracing Requirements for Nonstructural 12 Inch Rule:When a distributed system such as conduit ducts or pipes are suspended from the structure with hangers less than 12 inches in length, seismic bracing is not required. If the support carrying multiple pipes or conduits weighs less than 10 pound/feet of lineal weight of the component, the seismic bracing of the support does not have to be considered.
