33、y load carrying members and elements. The allowable stress design (ASD) criteria are intended as an alternative to the limit state design (LSD) criteria (see AS 1664.1). One design specification (ASD or LSD) applies throughout the design of a single structure. 1.2MATERIALSThe principal materials to
34、which these specifications apply are aluminiumalloysthatcomplywithAS 1734,AS 1865,AS 1866,AS 1867and AS 2848.1. Those structural members frequently used are listed in Table 3.3(A). 1.3SAFETY FACTORS 1.3.1Building type structuresBasic allowable tensile stresses for buildings, structural supports for
35、highway signs, luminaires, traffic signals and similar structures shall be the lesser of the minimum yield strength divided by a factor of safety of 1.65, or the minimum ultimate tensile strength divided by a factor of safety of 1.95. Other allowable stresses for buildings and similar structures sha
36、ll be based upon the factors of safety shown in Table 3.4(A). 1.3.2Bridge type structuresBasic allowable tensile stresses for bridge type structures shall be the lesser of the minimum yield strength divided by a factor of safety of 1.85, or the minimum ultimate tensile strength divided by a factor o

45、elastic structural analysis and engineering design. The formulas and methods for determining allowable stresses in this Standard have been simplified in many cases for ease of computation but are not intended to preclude the use of more rigorous analysis. 2.3LOADINGThe loads on the structure shall b

When computing allowable stresses in Australia, the most adverse load combination from the following shall be used: (a)G + Q (b)0.75 (G + Q + Wp) (c)0.75 (G + Q + Feq) (d)0.75 (G
47、+ Wp) where G=dead load Q=live load Wp=wind load based on basic wind speed Vp Feq=earthquake load Wp=wind load causing stresses of opposite sign to the dead load G=that part of the dead load that cannot be removed from the structure In the case of wind and ice loads, the form of the structure and an
48、y of its exposed components (e.g. increased area exposed to wind due to icing) shall be considered.
