GENERAL

1. NO BRACING IS REQUIRED IF THE TOP OF THE DUCT OR PIPE IS SUSPENDED 12 INCHES OR LESS FROM THE SUPPORTING

STRUCTURAL MEMBER.

2. WALLS, INCLUDING DRYWALL PARTITIONS, MAY REPLACE REQUIRED TRANSVERSE OR VERTICAL

BRACING FOR DUCTWORK OR PIPING.

3. ALL SEISMIC RESTRAINTS SHALL MEET OR EXCEED REQUIREMENTS OF SMACNA PUBLICATION

"SEISMIC RESTRAINT MANUAL GUIDELINES FOR MECHANICAL SYSTEMS" 1991 EDITION.

DUCTWORK

4. BRACE ALL RECTANGULAR DUCTS OF 6 SQ. FT. CROSS SECTIONAL AREA AND LARGER.

BRACE ALL ROUND/OVAL DUCTS 28 INCHES IN DIAMETER AND LARGER.

5. TRANSVERSE AND VERTICAL BRACING SHALL OCCUR AT 30 FOOT INTERVALS, MAXIMUM. LONGITUDINAL BRACING SHALL OCCUR

AT 60 FOOT INTERVALS, MAXIMUM.

PIPING

6. BRACE ALL PIPES 2 1/2 INCHES IN DIAMETER AND LARGER. IN MECHANICAL ROOMS ALSO BRACE 1 1/4", 1 1/2" AND 2 INCH PIPING AS FOR 2 1/2" PIPING. BRACE ALL FUEL GAS AND COMPRESSED AIR PIPING 1" AND LARGER.

7. TRANSVERSE AND VERTICAL BRACING SHALL OCCUR AT 40 FOOT INTERVALS, MAXIMUM UNLESS NOTED OTHERWISE.

LONGITUDINAL BRACING SHALL OCCUR AT 80 FOOT INTERVALS, MAXIMUM. WHEN THERMAL EXPANSION OR CONTRACTION IS INVOLVED, PROVIDE LONGITUDINAL BRACING AT ANCHOR POINTS. THE LONGITUDINAL BRACES AND THE CONNECTIONS MUST

BE CAPABLE OF RESISTING THE FORCE INDUCED BY EXPANSION AND CONTRACTION.

8. AT PIPE RISERS, WHEREVER POSSIBLE, SUPPORT THE WEIGHT OF THE RISER AT A POINT OR POINTS ABOVE THE CENTER OF

GRAVITY OF THE RISER.

9. DO NOT FASTEN ONE RIGID PIPING SYSTEM TO DISSIMILAR PARTS OF THE BUILDING THAT MAY RESPOND IN A DIFFERENT MODE

DURING AN EARTHQUAKE; FOR EXAMPLE, A WALL AND A ROOF.

10. DO NOT USE BRANCH LINES TO BRACE MAIN LINES.

EQUIPMENT

11. FLOOR OR PAD MOUNTED EQUIPMENT, WITHOUT VIBRATION ISOLATORS, SHALL BE BOLTED TO THE OTHER SUPPORT.

12. FLOOR MOUNTED EQUIPMENT, WITH VIBRATION ISOLATORS, SHALL BE PROVIDED WITH LATERAL AND VERTICAL RESTRAINING

DEVICES ON ALL SIDES OF THE BASE TO RESTRICT DISPLACEMENT OF THE EQUIPMENT.

13. ON ALL SIDES OF SUSPENDED EQUIPMENT, PROVIDE BRACING FOR RIGID SUPPORTS AND PROVIDE RESTRAINTS FOR

RESILIENTLY SUPPORTED EQUIPMENT.
