Uni-Pier®construction data

for single-storey buildings

65 x 65 x 2.0 mm (G350) and 75 x 75 x 2.5 mm (G350)

This document provides construction

data needed to use LYSAGHT Uni-Piers

in single storey buildings.

Uni-Piers are available in two cross-

sections. 65 x 65 mm is available in

lengths from 200 mm to 2800 mm, in

200 mm increments. 75 x 75 mm is

available in lengths from 200 mm to

4000 mm, also in 200 mm increments.

Wind regions

Data is given for seven wind regions in

five groups. Throughout the document

we have used the notation in AS

4055—1992, as follows.

AS 4055 Equivalent to:

N1 W28N permissible

W34N limit state

N2 W33N permissible

W40N limit state

N3 W41N permissible

W50N limit state

N4 & C1 W50N & W41C permissible

W61N & W50C limit state

N5 & C2 W60N & W50C permissible

W74N & W61C limit state

Notes

*All brickwork must be supported on

concrete footings.

*Interpolation within tables is

allowed.

Design Loads

Dead load of floor: 0.5 kPa

Live load of floor: 1.5 kPa

(for internal areas)

Live load of floor: 3.0 kPa

(for external areas, verandahs).

Both tile and sheet roofs are

considered.

Live load on roof: 0.25 kPa

Stud wall with plasterboard is

considered.

*Maximum height of the wall is 3.0 m.

*From ground to the highest point of

the roof should not exceed 5.5 m.

Roof pitch should not exceed 35º.

No bracing implies brick veneer type

of construction. Bracing implies clad

type of construction.

Capacity (Pages 2—5)

Except for the verandah (pier location 3),

the capacity tables are based on the

piers being equispaced in both

directions. (Grid spacing X = Grid

spacing Y)

To obtain the maximum pier load area

(m2) for your job:

1.Choose a pier location from

the Pier location box below.

2.Choose a Capacity table

(Page 2 or 4).

3.In the chosen table:

•Select the chosen pier location

number;

• Choose from timber or

rectangular hollow (RHS) steel

section bearers; or C–section

steel bearers.

4. Find the maximum pier load area

(m2) by selecting:

4.1 Roof width (fascia to fascia, see

sketch at right);

4.2 Maximum pier height;

4.3 Sheet or tile roofing;

4.4 Braced or not-braced piers.

Connections (Pages 6—7)

The tables give the fixing required for:

•Uni-Pier head to post;

•Uni-Pier fin plate to bearer;

•Uni-Pier to footing.

To obtain the required number of

fasteners for your job:

1.Choose a pier location from

the Pier location box below.

2.Use the chosen pier location number,

roof width and grid spacing in the

connection table on Pages6&7.

Bracing (Pages 8—9)

Bracing is fixed between Uni-Piers to

resist the forces resulting from wind

blowing on the walls and roof.

Bracing must be used in both

directions and (drawing below),

and each is designed separately.

Angle bracing (50 x 50 x 2.5mm

DURAGAL or equivalent) has greater

bracing capacity than strap bracing,

and is recommended.

Strap bracing 51 x 1.6 mm may be

used. It must be tightened using

tensioners (drawing on Page 11).

Bracing See drawings on Page 10

Find areas

Calculate Area and Area 

(drawing at left).

If a house is L–shaped, divide it into

two separate blocks and calculate the

wind loading on each block.



For Area , and then for Area , use

the formulas appropriate to the wind

region of the job (tables &below).



For Area and then for Area , get

the values from the Capacity table on

Page 9.

If the pier heights or pier spacings are

not the same throughout the job, you

will need to determine more capacities

(see examples on Page 9).



For Area and then for Area ,

divide the capacities obtained in Step

3, into the total bracing required (from

Step 2). Always round a fractional

answer up to the nearest whole value.

Both types of bracing are typically

fixed to Uni-Piers with two screws at

each end, no more than 20 mm from

the top or bottom of the Uni-Pier

(Page 11). Where the braces cross, fix

with one screw.

It is important to remember that

bracing seen on Elevation resists

wind loads from Direction , and vice-

versa (drawing below).

Determine the capacity of

bracing-sets that match the

height and spacing of your piers

Calculate the total bracing

capacity required

Determine the number of

bracing sets required

Table 

Table 

Example for Area with all piers the same

Job specifications

Dimensions for Area are 25 m x 4 m

Wind region = N2

All piers are at 2700 spacing and 1200 mm high

Angle braces will be used.

Find area

Area = 25x4=100m

Calculate the total bracing required

From Tables 1 and 2 on previous page:

Total bracing capacity required = Area x Ka x 1.63

=100 x 0.8 x 1.63

=130.4 kN

 Determine the capacity of bracing-sets that

match the height and spacing of the piers

From the table above, we find piers at 2700 spacing and

1200 mm high have a capacity of 30.2 kN.

 Determine the number of bracing sets required

Provide 5 sets of bracing.

Total Capacity of 5 sets of bracing:

30.2 x 5 = 151 kN is safe.

Example for Area with piers in 3 sets

Job specifications are the same as the other example

except:

2 sets of piers 2700 spacing and 600 mm high

1 set of piers 2700 spacing and 1200 mm high

2 sets of piers 2700 spacing and 1800 mm high

 Find area

Area = 25x4=100m

 Calculate the total bracing required

Total bracing capacity required = 130.4 kN (see example

at left)

 Determine the capacity of bracing-sets that match

the height and spacing of the piers

From the table above:

Sets of piers Capacity

2 off 2700 spacing and 600 mm high 2 x 32.2 = 64.4 kN

1 off 2700 spacing and 1200 mm high1 x 30.2 = 30.2 kN

2 off 2700 spacing and 1800 mm high2 x 27.4 = 54.8 kN

TOTAL CAPACITY = 149.4 kN

Step  requires 130.4 kN, so the total capacity of all 5

sets (149.4 kN) is safe, and no other combination of

these sets will do.
