Glulam Beam Span Tables, Revision 3, February 2015 4 St Fe De at a s em tu ign re en s t 1 Introduction This submission presents design span tables for Techlam GL8, GL10 and GL12 grade gluelaminated rafters, ridge beams and lintels to be used for domestic and residential self contained dwellings. Strength and deflection limitations under permanent load, live load and wind load are considered. Typical performance specifications are described. 2 Structural Analysis 2.1 Reference documents: Structural analysis/design conforms to the following standards: Table 1. Standards & Codes NZS1170 [1] New Zealand Standard: Structural Design Actions. NZS 3603:1993 [2] New Zealand Standard: Timber Structures. NZS 3604:2011 [3] New Zealand Standard: Timber-framed buildings 2.2 Techlam Beam Properties: Rafters, ridge beams, roof lintels and floor lintels using GL8, GL10 and GL12 glue-laminated timber are considered. Beam depths range from 135 to 585mm. The rafter breadths are 42mm, 65mm or 88mm. The ridge beam breadths are 88mm and 135mm. The roof and floor lintel breadths are 88mm. Relevant material properties are given for each grade below (See table 2) Table 2.

Glulam Beam Span Tables, Revision 1, February 2015 Back to Menu 2.3 Beam Loading: Permanent load (G), live load (Q) or Wind (W) loading is considered for the span tables. The following load cases have been applied: Table 3. Load Cases Limit State Ultimate Serviceability Load Case Description 1.35G Permanent 1.2+1.5Q Uniform and concentrated live load 0.9G+W Wind uplift 1.2G+W Downward wind G+ΨLQ Long-term deflection G+ΨSQ Short-term deflection WS Wind deflection 2.3.1 Permanent loads, G: Permanent loads for the roof and floors are given the table below and must include the selfweight of the glue-laminated beams. Light and heavy roof cladding is considered. For the floor lintel beams, light external cladding (not exceeding 30kg/m2) and 2.4m stud height is assumed. 2.3.2 Live loads, Q: Live loads for the roof and floors are given in the table below. These live loads are appropriate for domestic or residential self-contained dwellings. Table 4.

Glulam Beam Span Tables, Revision 3, February 2015 5 2.3.3 Wind loads, W The range of ultimate design wind velocities from NZS3604:2011 [3] are applied (see Table 5). The ultimate and service wind pressure is considered for strength and deflection checks respectively. Pressure coefficients (Cp) are in accordance with NZS1170.2 [1]. The worst case upward and downward pressure coefficient for the roof is taken as -0.9 and 0.5 respectively. An upwards pressure coefficient of -1.6 is applied to eaves. Table 5.

The bending strength is reduced by the strength reduction factor (Φ) and the load duration factor (k1) for permanent load. The strength reduction factor (Φ) is 0.8. The load duration factor (k1) for different load combinations are given in Table 6. The parallel support factor (k4) and the size factor (k24) from NZS3603 [2] are conservatively taken as 1.0. It is assumed that all beams are sufficiently restrained to prevent lateral-torsional buckling, and therefore, the k8 factor from NZS3603 [2] is taken as 1.0. Further information on the properties of each beam is given in Appendix A. Table 6. Load Duration Factors Element Ridge beam and roof lintel © Copyright Table 6.

Long term (G+ψlQ), short term (G+ψsQ) and service wind loading (Ws) deflection limits recommended by NZS1170.0 [1] are applied, which are a ratio of the maximum span, L. In addition, an absolute deflection limit of 12mm is used for service wind loading (Ws). For the long-term (G+ψlQ), the short-term (G+ψsQ) and service wind (Ws) load cases a creep factor (k2) of 1.5, 1.0 and 1.0 is applied respectively. Vibration performance requirements have not been considered for floor lintels. Table 7.

Ridge Beam Loading Figure 1. Rafter Loading 2.6 Beam loading arrangements The loading arrangement for the rafters, ridge beams, roof lintels and floor lintels are described in the Figure 1, 2, 3 & 4 respectively. For the ridge beam, roof and floor lintels the loaded width (LW) of each beam is taken as the half span of the rafters or joists which run in the orthogonal direction. The roof loading varies depending on the slope of the roof (α). Two ranges of roof slope are considered; 0 to 25 degrees and 25 to 45 degrees. For the rafters, roof and floor lintels a maximum eve width of 0.6m has been assumed. © Copyright of Techlam. Glulam Beam Span Tables, Revision 3, February 2015 7 Figure 3.

Timber is to be kiln dried to a moisture content of not greater than 15% at the time of lamination and installation. Timber is to be for internal use only (fully protected from the weather and inside the building envelope). All timber treatment is to comply with NZS 3640:2003 and AS/NZS1604.5:2002. To mitigate long-term beam deflection for beams spanning over 3m, a mid-span upwards pre-camber equal to the span length divided by 500 is recommended. All timber shall be separated from concrete or external timber (such as bearers) using a damp proof membrane. 4 Span tables The span tables for the rafters, ridge beams, roof lintels and floor lintels are given in Appendix B, C, D and E respectively. Note, interpolation of the maximum span between adjacent rafter spacing’s or loaded width’s is permissible. 5 Disclaimer Whilst every care has been taken to ensure that the above span tables are accurate, the authors/mlb Consulting Engineers take no responsibility for any errors or omissions or for any specifications or work based on its contents. Furthermore, the designer must satisfy themselves that the design assumptions listed in this guide are appropriate for the beams intended purpose. Refer to mlb Consulting Engineers for further information regarding the design assumptions associated with these span tables. 6 References [1] NZS1170.0. (2002).
