Guide Specication for Wind Bearing Steel Studs

reproduced in any form without the written permission of the publisher.

SPECIFIER NOTES:

This specication is written on the assumption that structural

design of the framing is the responsibility of the Contractor. It also

assumes that division of the work between subcontractors is the

responsibility of the Contractor alone, and done without reliance

on the specications.

For use as a contract document:

• Delete Specier Notes

• Choose appropriate selections in square brackets

• Delete selections in square brackets that do not apply

• Make any other project specic amendments that are

appropriate.

This publication replaces the previous edition dated January 2011.

1.4 Quality Assurance

Retain a Professional Engineer registered in [Canada]

[the province of __________ ] to design the wind

bearing steel stud wall system; to prepare, seal

and sign all shop drawings; and to perform eld

review. Shop drawings shall show both design and

installation requirements.

1.5 Design Criteria

.1 Design shall be based on Limit States

Design principles using factored loads and

resistances.

.2 Loads and load factors shall be in

accordance with the National Building

Code of Canada. For wind load calculations,

the reference velocity pressure, q, shall be

based on a 1 in 50 probability of being

exceeded in any one year.

.3 Resistances and resistance factors shall be

determined in accordance with the National

Building Code of Canada and CSA-S136.

.4 Conform to the requirements of re

rated assemblies [specied] [ which have

been tested in accordance with CAN/

ULC-S101 and provide a re resistance

rating of [ ___________ ] ].

.5 Stud depths are shown on the drawings.

Adjust stud material thicknesses and

spacings, as required by the design criteria.

Use greater or lesser stud and joist depths

only if approved by the [Project Engineer]

[Architect].

Specier Note: Note that maximum spacings (Section 1.5.6)

and minimum design thicknesses (Section 1.5.7) must also

be considered. In addition, to avoid contractual confusion:

• Do not show stud and joist thicknesses or spacings on

the Architectural or Structural drawings

• Do not use gauge as a thickness designation.

.6 Space wall studs at [305] [406] [610]

[ ____ ] mm maximum. Use lesser stud

spacings if required by the design criteria.

Specier Note: The structural performance of the collateral

facing materials such as gypsum drywall, plywood or OSB

and their associated performance as air barriers, vapour

retarders, etc. will also limit the spacing of supporting

members.

.7 For studs, conform to the design

thicknesses in Table 1. Use greater stud

thicknesses if required by the design criteria.

Specier Note: The minimum base steel thicknesses in

Table 1 are 95% of the design thickness as limited by

CSA-S136

[For wall studs supporting brick veneer, the minimum

thickness exclusive of coating shall be the greater

of the minimum thicknesses in Table 1 or [1.087 mm]

[ _____ ] ].

Specier Note: The minimum design thicknesses in Table 1

satisfy the requirement in S136 for web height to thickness

ratio not greater than 200 assuming an inside bend radius

of 2t.

.8 The minimum thickness for bridging channel

shall be 1.087 mm. Use greater bridging

channel design thickness if required by the

design criteria.

.9 The minimum thickness for clip angles shall

be 1.367 mm. Use greater clip angle

thickness if required by the design criteria.

.10 Maximum exural deections under

specied wind loads shall conform to the

following:

.1 Wall studs supporting masonry veneer

shall meet the requirements of CSA

S304.1 with stud deections limited to

L/360.

Specier Note: The deection and spacing of steel

studs supporting masonry veneer is controlled by the

requirements of the masonry design standard, CSA S304.1.

.2 Wall studs supporting other nishes,

L/360.

.11 Design connections to accommodate

vertical deection movement of the

structure, frame shortening and vertical

tolerances without imposing axial loads

onto the framing. Leave a minimum gap

of [12 mm] [ ____ ]. Larger gaps may be

required to accommodate structural

movement. Co-ordinate with the Project

Structural Engineer.

.12 Limit free play in connections perpendicular

to the plane of the framing to ± [0.5]

[ ____ ] mm relative to the building structure.

Specier Note: Free play does not include the deection

under applied load. The provisions in 1.5.12 do not apply to

masonry ties covered by CSA-A370.

.13 Design components and assemblies

to accommodate specied erection

tolerances of the structure.

.14 Design bridging to prevent member rotation

and member translation perpendicular to

the minor axis. Provide for secondary stress

eects due to torsion between lines of

bridging. [Collateral sheathing may be

used to help restrain member rotation and

translation perpendicular to the minor

axis]. [Do not rely on collateral sheathing to

help restrain member rotation and translation

perpendicular to the minor axis]. Provide

bridging at 1524 mm o.c. maximum.

Space bridging at equal intervals over

the span length of the member. Closer

spacings may be required to satisfy

structural requirements.

Specier Note: Some sheathing materials such as gypsum

drywall may lose their structural integrity when subject to a

moist environment or when subjected to a sucient number

of load cycles. Such materials are generally not suitable

to act as structural bracing. If the sheathing is utilized

for bracing, it is standard practice in the industry to also

provide sucient steel bridging to align members during

erection and to provide the necessary structural integrity

during construction as well as in the completed structure.

.15 Design anchorage and splice details for

bridging.

.16 Design for local loading due to anchorage of

cladding and interior wall mounted xtures

where shown.

.17 Connections between wind bearing steel

stud members shall be by bolts, welding or

sheet metal screws.

.18 Provide head, sill and jamb members and

connections to frame openings larger than

[100] [ ____ ] mm in any dimension.
