AS 1170 deals with minimum design loads on structures (also known as the SAA Loading Code)
Loading: The loads on the structure shall be in accordance with the applicable parts of AS 1170.
Load Combinations and Load Factors: The required forces, moments and stresses for the applicable loads shall be determined by structural analysis for the load combinations as indicated in AS 1170.1.
A factor of 1.25 shall be applied to dead load for ultimate load combinations
Wind Loading: Design loads on noise fences shall be in accordance with AS/NZS 1170.2
Where noise fences are within 4 metres of the road edge line, the design shall include an additional load of 0.65 kPa representing dynamic suction imposed by moving vehicles for serviceability wind. For noise fences greater than 4.0 m high, the suction load shall only be applied to the lower 4.0 m.
Attention is drawn to the specific requirements of Table D2 of AS/NZS 1170.2 for end panels (i.e. 0 to 2h) and internal panels.
