Eca seismic restraint manual

duct. This section will be based on information contained in SMACNA’s “Seismic Restraint Manual – Guidelines for Mechanical Systems”. S – Basic Terms and Definitions: Seismic restraints for pipe and duct are separated into two categories. 1. Transverse seismic restraints (T): These act to prevent the pipe or duct from swinging side. Sasco Seismic Restraint Manual The information in this manual is subject to Read Jones Christoffersen Ltd.’s structural engineering disclaimer found on page 1 of this manual. 7 SMACNA – Section The following is taken from section . The SMACNA Seismic Restraint Manual – Guidelines for Mechanical Systems 3rd Edition has been an industry standard for many years. And, even though it is not specifically identified as a reference document for / IBC, ASCE/SEI , it is still widely accepted in most.

This manual begins with a nontechnical explanation of seismic loads to help designers and builders appreciate the need for seismic restraints. Chapter 2 explains the steps in using the drawings and tables and includes two worked examples. Chapter 3 outlines the general requirements for restraints. drawings and specifications, seismic restraint submittals, and manufacturer’s instructions. Also, refer to the manual that was used to design the seismic bracing. This manual is required to be on the job site. Refer to approved construction documents that show the overall layout of the duct and pipe runs throughout the building. Longitudinal Seismic Restraint Spacing: S L = 20 ft. Maximum The SMACNA seismic restraint spacing recommendations do not appear to take into account the gross buckling of the pipe or duct, and have been simplified to apply to all Seismic Hazard Levels. – Maximum Seismic Restraint Spacing Based on the Gross Buckling.
