Te sstem consists of soid bridin ssembies between purins nd

Purlin bridging
hOOk-lOk II bridin into Zed or Cee purins m be insted in
numerous ws. Te norm procedure is to commence from te eve or

a tpic insttion procedure is:
Step 1:Inst te fsci bridin ssemb b insertin te octor endinto te oes of te first purin, nd botin te fsci brcetto te fsci purin.
Step 2: Inst te stndrd bridin ssembies worin towrds, ndfinisin t, te ride purin. Stndrd ssembies re insted

Step 3: Were ppicbe, repet Steps 1 nd 2 for te opposite side ofte roof. If ppernce is considertion, te bridin runs on
bot sides of te roof soud be swun into position from te
sme end of te roof.
Step 4: Inst te ride bridin ssemb b fittin te cmp ends

Te recommended procedure is to commence t foor eve nd wor

to te sb.
Step 2: adjust te irt foot ssemb to eve off te bottom irt. Were
te sb is not et poured, temporr support is required to

Step 3: Inst stndrd bridin ssembies s described in Step 2 forpurin bridin, worin towrds te eves.
Step 4: at te top irt, te octor is secured into position wit two

If ppernce is considertion ensure te irt nd purin
bridin re insted fcin te sme direction.
Were irt ner is used it is insted b fittin te cmp
end over te st insted octor end nd swinin te bridinround, ten botin te turnbuce to te fsci bridin.
In projects where no girt foot assembly is used, particular care
in design and construction is required.
We recommended te foowin precutions durin construction:
1. Te roof seetin soud be insted before te turnbuce of te irt

Design philosophy
Te imit stte cpcit tbes ve been compied usin finite eement
fexur torsion bucin nsis for modein te woe purin sstem.
Te mode considers bot in-pne distribution of xi force, ser force
nd bendin moments, s we s out of pne bucin modes.Te finite eement fexur torsion bucin nsis ssumes tt:
purins bend bout te xis wic is perpendicur to te web;
tere is continuit t te ps;
tere is minor xis trnstion nd twistin restrint t te bridin
points;
tere is ter stbiit in te pne of te roof t intern supports nd
te ends of cntievers; nd
bot screw-fstened nd conceed-fixed cddins provide restrint.
a desin ccutions for bot strent nd servicebiit re in
ccordnce wit aS/NZS 4600:1996 Cod formed stee structures.
DeflectionTere re no specific rues overnin cceptbe defections, tou
structur codes ive uidnce. you need to consider te specific
requirements of n structure. It m be necessr to desin for defection
under more tn one od combintion. See so assumptions used in
tbes.
Axial loads
Were section is not oded to its fu cpcit in bendin, it s
reserve of strent to crr some xi od. Tis reserve in purins nd
irts cn be used to trnsmit forces due to wind odin on end ws, or to
resist forces due to brcin of w nd roof structures.
Were required, te combined bendin nd xi od cpcit soud be
ccuted usin aS/NZS 4600:1996 Cod-formed stee structures. advice isvibe from our informtion ine.
Point loads
Te vues in tis pubiction ssume uniform distributed odin.
however, in mn ppictions (ie te mountin of services nd
mintennce equipment) te ods ppied to structure re point ods.
Tus, to use tese tbes for point odins, te ods must be converted to
equivent distributed ods.
Te tbe on te foowin pe ives conversion formue for ods on
simpe spns nd pped spns. Te ve been derived from common
pubised moment nd ser dt, nd ive conservtive conversions.
For simpe spns te formue re strit forwrd. For non-continuous
pped spns te formue depend on te number of spns, te position ofte spn nd te ppin rtio; tus te worst-cse confiurtion s been
used, nd te vues m be sfe used for end spns, interior spns nd
n ppin rtio reter tn 10%.
Formue for ods on continuous unpped confiurtions, nd for
defections in confiurtions, re not iven but m be derived simir.
Smbos used in tbe for conversion of point ods
P = sine point od (N)
l = spn (m)
= rer distnce from support (m)
b = smer distnce from support (m)w = equivent uniform od (N/m)
N = number of point ods over one spn (for 6 or more ods)
