THE ADVANTAGES OF USING STEEL JOISTS
Using a steel joist and steel deck system for floor and roof construction has proven
itself to be a most advantageous solution. It can result in substantial savings
based on:
• Efficiences of high-strength steel;
• Speed and ease of erection;
• Low self-weight of roof and floor construction allowing for smaller columns and
foundations than for a concrete structure;
• Increased bay dimensions, which reduces the number of joists and columns
and simplifies building erection;
•
Greater floor plan layout flexibility for the building occupant due to the
increased bay dimensions;
• Maximum ceiling height due to installation of ducts through the joist web
system;
•E
 asy adaptation to acoustical insulation systems;
• Floor and roof composition having long-term resistance to fire, as established
by the Underwriters Laboratories of Canada (ULC)

DESCRIPTION OF A JOIST GIRDER
DEFINITION
A joist girder is a primary structural component of a building. Generally, it supports
floor or roof joists in simple span conditions, or other secondary elements (purlins,
wood trusses, etc.) evenly spaced along the length of the joist girder. The loads
applied to a spandrel joist girder come from one side, while on an inside bay the
loads are applied on either side of the joist girder

COMPONENTS OF A JOIST GIRDER
An open web joist girder, or commonly known as a “cantruss” at Canam, is
composed of a top chord and a bottom chord, which are usually parallel to each
other. These chords are held in place using vertical and diagonal web members. In
conventional construction, a joist girder rests on a column and the bottom chord is
held in place horizontally by a stabilizing plate

The standard main components are:
1. Top and bottom chords: two angles back-to-back with a gap varying between
25 mm (1 in.) and 76 mm (3 in.),
2. Diagonals: U-shaped channels or two angles back-to-back,
3. Verticals: U-shaped channels, boxed angles or HSS,
4. Shoes: two angles back-to-back

General information
ADVANTAGES OF JOIST GIRDERS
The use of open web joist girders is widespread in North America, mostly in the
United States, for roof construction of commercial and industrial buildings. The
joist girders are advantageous compared with conventional load bearing systems
composed of beams with a W profile. Here are the various options for supporting
systems when designing a steel building:
Simple beam
Gerber system
Joist girder
Carrying system
Economical factors associated with the specification of joist girders include
the following:
1. The steel used in joist girders has a yield strength higher than steel used for
shaped or welded beams: 380 MPa (55 ksi) versus 350 MPa (50 ksi)

2. Better cost control for material purchases (angles) on the Canadian market
compared with importing the beam sections

3. Open web joist girders are lighter than the full web beams of the same depth

4. The speed and ease of site erection improves jobsite co-ordination

5. The joist girders can be used to facilitate the installation of ventilation ducts
and plumbing as compared to a beam

General information
If a larger opening is required, a diagonal member can be removed if the top and
bottom chord are reinforced

3. B

4. Regular joist spacing must be maintained by the building designer by lining
up the joists on either side of the joist girders

5. Rectangular bays are recommended, in a roof or floor system using joist
girders and joists, where the longest dimension corresponds to the joist span,
while the shortest dimension corresponds to the joist girder span. An optimal
Joist girder rectangular bay would typically have a ratio of joist span to joist girder span
of approximately 1.5

STEEL
Our joist and joist girder design makes use of high strength steel purchased in
accordance with the latest issue of the standards below:
•C
 old formed angles and U-shaped channels: ASTM A1011;
Cold formed angle
•H
 ot rolled angles and round bars: CAN/CSA-G40.20/G40.21

DESIGN STANDARDS
Joist and joist girder design is based on the latest issue of the design standards in effect:
Canada: United States:
Hot rolled angle • CAN/CSA S16–01 • SJI
• CAN/CSA S136–07
• NBCC 2005
QUALITY ASSURANCE
Over the years, we have established strict quality standards. All our welders,
inspectors, and quality assurance technicians are certified by the Canadian Welding
Bureau (CWB). We do visual inspections on 100% of the welded joints and
non-destructive testing if required

Frequently Asked Questions

How does canam handle end gravity moments in joists?

In this way, the joist or joist girder follows the condition for simple span condition under dead loads. In the case of end gravity moments, Canam will assume that they are caused only by the live load, unless otherwise specified by the building designer.

What are the connectors for steel deck and canam joists?

CONNECTORS BETWEEN STEEL DECK AND CANAM JOISTS IN BRACING Canam joists can be used as vertical, bottom or top chords in a horizontal bracing with wind or seismic loading. In this case, the steel deck/joist top chord connector should be verified carefully to ensure that the compression member can be laterally maintained.

What kind of load can be applied to a joist?

Loads applied to joists and joist girders can be uniform, partial, concentrated, axial, or moment. Snow pile up loads represent a special partial load case. Uplift loads are applied in an upward direction and should always be specified as a gross uplift load.

What is a special joist canam?

SPECIAL JOISTS Canam can design and manufacture special joists to suit the conditions required by the building designer. A non standard joist can have particular assembly conditions and/or a special shape as described on page 27.
