GENERAL INFORMATION 1These guidelines are intended to provide information for the seismic restraint of nonstructural componentsin buildings based on the California Code of Regulations (CCR), Part 2, Title 24. Nonstructural componentsmay include hospital piping, electrical conduit, cable trays, and air handling ducts.2. Seismic horizontal force factor Zp ZIC pWp .ZICpWp .4 for seismic zone 4 1.5 0.75 Weight of Component3. When supporting pressure piping, spacing of seismic bracing should not exceed two (2) times the verticalsupport spacing. Stress in the pipes that are comparable to those required by ASME B31.1-1986 will bemaintained.4. The CCR, Part 2, Title 24, Table 23-P, Footnote 12 states the following:Seismic restraints may be omitted from the following installations:a.b.c.d.Gas piping less than one (1) inch inside diameter.Piping in boiler and mechanical equipment rooms less than 1.25 inches inside diameter.All piping less than 2.5 inches inside diameter.All piping suspended by individual hangers twelve (12) inches or less in length from the top of pipe tothe bottom of the support for the hanger.e. All electrical conduit less than 2.5 inches inside diameter.f. All rectangular air handling ducts less than six (6) square feet in cross-sectional area,g. All round air-handling ducts less than 28 inches in diameter.h. All ducts suspended by hangers 12 inches or less in length from the top of the duct to the bottom of thesupport for the hanger.5. Unistrut nuts and bolts mounted to the Unistrut channels shall be tightened to the following minimumtorques:Bolt Diameter (In.)1 4Bolt Torque (Ft.-Lbs.)Bolt Diameter (In.)1611195 16 83 2 83 45Bolt Torque (Ft.-Lbs.)501001256. The charts and information presented on the following pages are intended as a guide only. Prior toinstallation, the user and/or project engineer shall determine structural adequacy of supports and thesupporting structure and shall also determine compliance with applicable codes.Use of this manual requires that layout drawings for the pipe/duct/conduit be used to determine bracelocations, sizes, anchorage and forces. These drawings are an integral part of the approval of the lateralforce bracing system. The layout drawings shall be submitted to OSHPD as a deferred approval item priorto the installation of the lateral bracing system.R E N E W E DFixed Equipment AnchorageOffice of Statewide Health Planning and DevelopmentR-012035660 Clinton StreetWayne, Michigan 48184February 1, 2002****Valid for 3 Years Maximum****William MerkelStructural EngineerBill Staehlin(916) 324-9106Date:PH: (800) 521-7730FAX: (734) 721-4106Page1-1
DESIGN PROCEDURES FOR TRAPEZE HANGERS1. Determine the support spacing using the smallest pipe diameter2. Calculate the total weight of the pipes plus contents (W) on each trapeze using the following equation:W S x (p1 p 2 p3 pn)W Total weight on trapeze (Ibs.)pn Weight of pipe plus water (lbs./ft.)(page 2-1, table 1).S Support spacing (ft) (page 2-1, table 1).3. Select clamps (pages 3-3, 3-4, tables 6 & 7). Either style, P1100 Series or P2558 Series can be used.Maximum pipe support spacing should be as per chart 1, row 3 page 3-12.4. Select trapeze member using the total weight on the trapeze and the length of trapeze required to fit thegiven pipe sizes and quantities (page 3-1, 3-2, tables 2-5).5. Calculate horizontal seismic force (Fh) assuming braces on alternate trapeze supports (page 2-2, figure 1).Select a brace assembly (page 3-11, details I-V) that has an Fh value that meets or exceeds the horizontalseismic force.If necessary, seismic force can be recalculated with braces on every trapeze (see figure 2).Pipe DataTable 1Data for Schedule 40 Standard Weight PipeIncluding Horizontal Seismic Force of .50 GPipeSizeIn1 2 4111 2221 234683PipeSectionModulusInMax.SupportSpacing PerASME B31.1*(S) FeetWeight OfPipe PlusWater(P) .0601.7203.2108.50016.800Horizontal SeismicForce/Ft. of Pipe(.5 x Pipe .7625.15*ASME B31.1 does not list all sizes shown, therefore some sizes have been proportioned between.**Spacing limited by CBC 1998.For gas pipe and copper pipe see CBC 1998 for support spacing.R E N E W E DFixed Equipment AnchorageOffice of Statewide Health Planning and DevelopmentR-012035660 Clinton StreetWayne, Michigan 48184February 1, 2002****Valid for 3 Years Maximum****William MerkelStructural EngineerBill Staehlin(916) 324-9106Date:PH: (800) 521-7730FAX: (734) 721-4106Page2-1

DESIGN PROCEDURES FOR TRAPEZE HANGERS6. Check compression and tension in the rod. When diagonal braces are used to stabilize trapeze hangers,they will cause tension and compression forces to be added to the tension already in the rod (see figure 3).a. Select threaded rod that has a tension strength that meets or exceeds the required tension(page 3-14, table 10)Brace on alternate hangersBrace on every hangerTmax 1.5W (page 2-2, figure 1)Tmax 1.0W (page 2-2, figure 2)b. Check compression in the selected threaded rod. When braces are used on every trapeze, no stiffeneris required. If the rod is subject to compression, it may require a stiffener. Determine the percentage offull stress capacity on the rod using the following equation:Actual Compression Load Allowable Compression Load (page 3-13, table 9)Select clip spacing (L) based on percentage above (page 3-13, table 9).7. Determine if longitudinal braces are required using the following equation:Brace Spacing Allowable Fh .25W(# of bays)Allowable Fh Determined by assembly selected (page 3-11, details I-V)8. Check forces on pipe clamps using following equations:Vertical Force Pipe Wt. per foot x Trapeze spacingTransverse Force Pipe Wt. per foot x Lateral Brace Spacing x 0.5Longitudinal Force Pipe Wt. per foot x Longitudinal Brace Spacing x 0.5See pages 3-3 and 3-4 for allowable design forces. Revise spacing of braces if necessary.9. Check trapeze member for combined vertical and lateral seismic loads using the following interactionequation: (Revise trapeze spacing or brace if necessary).[ActualVertical Force[] x[LateralReduction Factor]AllowableVerticall Force [ActualHorizontal Force] []x[LateralReduction Factor]AllowableHorizontal Force] 1.3310.

DESIGN PROCEDURES FOR SINGLE PIPE HANGERS1. Select hanger type (pages 3-6, through 3-10) given the diameter of the pipe.2. Determine the support spacing (page 2-1, table 1) and corresponding rod diameter(page 3-12, chart 1, row 2). Calculate the total weight of the pipe and contents (page 3-12, chart 1, row 6)or use the following equation:W SxpW Total weight on hanger (Ibs.)p Weight of pipe plus water (Ibs./ft.)S Support spacing (ft)3.

Check maximum tension of rod (page 3-12, chart 1, row 8).5. Compression (see page 2-3, step 6b).6.

Concrete aggregate must comply withUBC Standard No. 26-2. Allowable loads are based on allowable loads listed in the ICBO Reports 4627 datedFebruary 2001 and 1372 dated March 2000. Tabulated loads are for anchors installed in the tension (underside)zone of structural members (beams and slabs) and have been reduced to 80% shear per OSHPD guidelines.Anchor diameter refers to the thread size.2These tension values are only applicable when the anchors are installed with special inspection as set forth insection 306 of the Uniform Building Code and apply to anchors installed a minimum of 12 diameters on centerand a minimum edge distance of 10 diameters. When installing anchors in tension zone of concrete, seeOSHPD IR26-6.3Fifty percent of the drilled-in expansion type anchor bolts shall be proof tested to the tabulated proof test load.4See page 5-2 for combined shear and tension interaction.R E N E W E DFixed Equipment AnchorageOffice of Statewide Health Planning and DevelopmentR-012035660 Clinton StreetWayne, Michigan 48184February 1, 2002****Valid for 3 Years Maximum****William MerkelStructural EngineerBill Staehlin(916) 324-9106Date:PH: (800) 521-7730FAX: (734) 721-4106Page5-1

Spacing and edge distance may be reduced to sixdiameter spacing and three-diameter edge distance, provided the values are reduced 50 percent. Linearinterpolation may be used for intermediate spacing and edge margins.3These tension values are applicable only when the anchors are installed with special inspection as set forth insection 306 of the code.
