ROOF BEAMS

Single and Continuous Spans

Restraint value for slenderness calculations is 1200 mm.

K6 factor of 1.0 used. K23 factor applied to bending strength.

J2 value of 1.5 used for DL Deflection. INCLUDES

Pre-camber radius of 0m used. 10 kg/m2

Roof Pitch of 25.0 deg used in load calculations. 20 kg/m2

N3 WIND AREAS Downdrag loads were ignored. 40 kg/m2

Total Uplift coefficient was 1.6 70 kg/m2

Deflection Criteria: 90 kg/m2

1: Dead Load = Span / 300 or maximum 20 mm.

2: Roof Live Load = Span / 250

3: Wind Uplift = Span / 150.

Timber Properties: Fb = 11 MPa, Elasticity = 13300 MPa

Density = 600 kg/m3, Fs = 1.25 MPa

Ft = 5.2 MPa, Fc = 11 MPa.

Load Cases:

1: Dead Load

2: Roof Live Load

3: Wind Uplift

Roof Beam table may be used for calculating sizes of -

Ridge Beam

Intermediate Beam

Bressumers

Under Purlins

MAX ROOF PITCH = 25 DEGREES

Roof pitch used in calculations is 25 degrees. For roof pitches greater than 25 degrees

but not exceeding 45 degrees you may multiply roof load width x 1.28

then use answer to enter table at correct load width.

CONTINUOUS SPAN ROOF BEAM

Continuous Roof Beam may have unequal spans, provided major span does not

exceed 1.25 times the length of the minor span, major span length should be

used in determining roof beam size.

To determine Roof Load Width from Figure 2 use formulas below.

Roof Load Widths (RLW)

Span (S)

Ridge Beam RLW = S3+S4

Intermediate Beam RLW = S2+S3

Under Purlin 2

Bressumer Beam RLW = S1+S2
