ESY-LOK® BRIDGING INSTALLATION
GIRT BRIDGING
The recommended procedure is to commence at floor level and work towards the eaves. A typical installation procedure is:
Step 1: A girt foot assembly can be configured by using (part no. 6) and (part no. 9). Bolt fix the assembly to the bottom girt. Due to the loads transferred to the bridging from the girts, the girt foot assembly must be anchored to the slab.
Step 2: Adjust the girt foot assembly to level off the bottom girt. Where the slab is not yet poured, a temporary support is required to keep the bottom girt level.
Step 3: Connect the bolted-end of a female-bolted (part no. 2) to the bottom girt. Once bolted in place, lock the opposing female end into the punched holes of the next girt.
Step 4: With the male end of the a male-female (part no. 1), it should be at right angle to the adjoining bridging before it is swung around and locked into place. The bridging should now be in a continuous direction and the opposing female end placed into the holes of the next girt.
Step 5: Continue locking in male end plates to female end plates up the wall. Between the 1st and 2nd rows of girts from the fascia, a male-bolted bridging (part no. 3) is required. The bolted end should be fixed to the top girt.
Step 6: At the top girt, a girt hanger assembly can be configured by using (part no. 6) and (part no. 8). The girt hanger is installed by bolting the end plate to the top girt and bolting the slotted channel / turnbuckle to the fascia bridging as illustrated in the diagram.
In projects where no girt foot assembly is used, particular care in design and construction is required.
If appearance is a consideration ensure the girt and purlin bridgings are installed facing the same direction.
We recommended the following precautions during construction:
1. The roof sheeting should be installed before the turnbuckle of the girt hanger is used to level the girts, which would impose loads on the fascia system; and
2. Provide a temporary girt support under the bottom girt until the installation of the wall cladding is complete for that section.
PURLIN BRIDGING
There are a number of ways to install the ESY-LOK® bridging system when erecting a SUPAZED® purlin design. A common approach is to begin at the ridge and work down the slope. A typical installation procedure may adopt the following steps (see the Bridging order form for enlarged illustrations of part numbers);
Step 1: Install the Bolted-Bolted ridge tie (part no. 4) by bolting each end plate into place. Alternatively, a threaded-rod can also be used (part no. 7).
Step 2: Following the slope of the roof in the downwards direction, place a female-bolted (part no. 2) at the ridge end. Once bolted in place, lock the opposing female end into the punched holes of the next purlin down the slope.
Step 3: With the male end of the a male-female (part no. 1), it should be at right angle to the adjoining bridging before it is swung around and locked into place. The bridging should now be in a continuous direction and the opposing female end placed into the holes of the next purlin.
Step 4: Continue locking in male end plates to female end plates down the slope. Between the 1st and 2nd rows of purlins from the fascia, a male-bolted bridging (part no. 3) is required. Between the 1st purlin and the fascia an adjustable bridging (part no. 6) is required to connect to the fascia purlin and the bridging installation is complete.
Other methods of bridging exist and include different bridgings (see the Bridging Order Form for more information). Consideration should be given to the direction of the channels in the bridging but are primarily a decision based on the aesthetics of the roof as seen from below.

DESIGN NOTES TO LIMIT STATE CAPACITY TABLESDESIGN METHOD
The purlin capacity tables have been compiled using a program that carries out the analysis and design for purlin systems composed of cold-formed members.
The analysis includes an in-plane structural analysis and a finite element lateral buckling analysis of complete purlin systems.
The design for both strength and serviceability limit states is performed according to AS/NZS 4600, including the calculation of section properties.
The finite element flexural torsional buckling analysis assumes that:
• all purlins bend about the axis which is perpendicular to the web
• there is continuity at the laps
• there is minor axis translation and twisting restraint at the bridging points and cleat supports
• the loading is uniform
• the cladding provides lateral restraint to the top flange of the purlin
DEFLECTIONS
The column in the design tables shows UDL load which results in deflections equal Span/150. Other deflection limits may be derived from given values using simple proportions.
INTERMEDIATE VALUES
Within a given bridging configuration, capacities for intermediate spans may be interpolated linearly.
PARAMETERS
The values given in the purlin capacity tables are based on the following design criteria and assumptions:
• the tables have been based on the use of approved product manufactured by Lysaght (purlin profile, bridging, purlin bolts and cladding) and installed in accordance with the details set out in this Lysaght Manual;
• cladding is fastened to the top (or outside) flange. Guidance has been given for the reduction of capacity where low restraint cladding is used;
• loads are assumed to be acting via the cladding;
• loads are acting in Outward or Inward direction;
• the capacity given is a uniformly distributed load (UDL) acting Outward or Inward and acting over the whole purlin configuration. Thus all design loads must be converted into an equivalent uniformly distributed value;
• a uniform distributed load (UDL) is given that will produce a deflection of Span/150 for the critical span of the configuration. These values are the same for both Outward and Inward acting loads. This value is NOT a design capacity;
• span configurations are either two or four spans;
• all span lengths in the configuration are equal;
• lapped span configuration is with a lap at each of the internal supports;
• laps are 15% of the span;
• all purlin sections are fastened through the web to cleat supports. All connections to cleats are with two purlin bolts (Standard bolt of Grade 4.6, High Strength bolt of Grade 8.8). Where a value is in bold type then the Grade 8.8 bolts are required;
BRIDGING
In most practical situations it would be necessary to use at least one row of bridging per span. For guidance, unbridged length limited to 20D is suggested (where D is the section depth). With large spans and deeper sections, a guide of 15D may be more appropriate.
In accordance with the latest provisions of AS/NZS 4600 Cold-formed steel structures, the purlin capacities have been calculated for Lysaght sections using approved Lysaght bridging systems, bolts and other accessories. Sections chosen using the data provided in the tables will perform as specified when the design, fabrication and erection are carried out in accordance with Lysaght recommendations and accepted building practice.

Outward Load Inward Load
Outward Load is defined as the load to pull the cladding off the flange. Inward Loads are those pushing the cladding onto the flange.
