Design Loads Duration of load/service class Table 4 Table 5 Dead loads are: Duration of load factor (J 2 ) Service class / exposure classification Sheet roof without ceiling 20 kg/m 2 1, 2 3 Severe/Adverse Sheet roof with ceiling 40 kg/m 2 Duration Fibro roof with ceiling 60 kg/m 2 Short term 12 months 1.5 2.0 3.0* Tiled roof with ceiling 75 kg/m 2 Notes: 1. Any beams to be used in service Class 3 are outside the scope of these span Timber floor with ceiling under 40 kg/m 2 Live loads are: roof (non trafficable) = 0.25 kPa minimum (1.8/area + 0.12) kPa or 0.25 KPa maximum. Floor loads (domestic) External - greater than 1 m above ground 1.5 kPa 2.0 kPa - Less than 1 m above ground 1.5 kPa tables, therefore specialist design advice should be sought from an engineer. In general, the size of this beam can conservatively be obtained by the following method: (a) Obtain the beam size for service class 1 & 2 (b) Obtain the EI xx from the "Section Properties" table for this beam (c) Obtain from the "Section Properties" table a beam size with an EI xx => 2/1.5 x EI xx of the original beam (d) Follow the recommendations of the GLTAA Technical Data sheet No 2: Glulam in weather exposed applications" * indicates severe / adverse conditions which are beyond the scope of these span tables and specialist design advice from a engineer should be sought. 2. Service classes 1,2 & 3 are defined in AS1328 ENGINEERING PROPERTIES Table 6 Characteristic strengths (MPa) Elastic moduli (MPa) Glulam grade Bending (F' b ) Tension parallel to grain (F' t ) Shear in beam (F' s ) Compression parallel to grain (F' c ) Short duration modulus of Elasticity parallel to the grain (E) Short duration modulus of Rigidity for beams (G) SmartLam GL17 40 20 4.2 33 16700 1100 CAPACITY FACTORS (Φ) FOR USE WITH SmartLam GL17: The capacity factor Φ for calculating the design capacity for a structural member depends upon the type of structural material and the application of the member as described in table 2.1 of AS 1720.1. SmartLam GL17 used as a structural element in structures presenting a low degree of hazard to life and other property in case of failure (includes houses) has a capacity factor Φ of 0.95. For other structural applications including beams within houses that support an area greater than 25 m 2 , the values of Φ should be obtained from Table 2.1 of AS 1720.1. All the tables within this document have been prepared with the value of Φ = 0.95 OTHER PROPERTIES : DIMENSIONAL TOLERANCES: Strength group SD5 Joint group JD4 Density ~ 650 kg/m 3 Service class 2 (EMC not to exceed 20% in service) ADHESIVE: Height or
PRE-CAMBER: All stock SmartLam GL17 beams are supplied with a built in camber of a radius of 600 metres. SmartLam GL17 beams can be ordered either straight or with or a user specified pre-camber.
