AS/NZS 4600:2005 pdf free.Cold-formed steel structures.Here is the part of the introduction:
AS/NZS 4600sets out minimum requirements for the design of structural members coldformed to shape from carbon or low-alloy steel sheet, strip, plate or bar not more than 25 mm in thickness and used for load-carrying purposes in buildings. It is also applicable for structures other than buildings provided appropriate allowances are made for dynamic effects.
AS/NZS 4600 does not apply to the design of structures subject to fire and brittle fracture.
Documents referred to in this Standard are listed in Appendix A and are indispensable for
the application of this document.
For the purpose of this Standard, the definitions below apply. Definitions peculiar to a particular clause or section are also given in that clause or section.
1.31 Action
Set of concentrated or distributed forces acting on a structure (direct action), or deformation imposed on a structure or constrained within it (indirect action).
1.3.2 Action effect (internal effects of actions, load effects)
Internal forces and bending moments due to actions (stress resultants).
1.3.3 Arched compression element
A circular or parabolic arch-shaped compression element having an inside radius-tothickness ratio greater than 8, stiffened at both ends by edge stiffeners. (See Figure 1.3(d).)
1.3.4 Assemblage of elements
A system of interconnected cold-formed steel elements that act together to resist earthquake action in such a way that the strength and deformation capacity of the system is not adversely affected by the buckling or crippling of any one element of the assemblage.
1.3.5 Bend
Portion adjacent to flat elements and having a maximum inside radius-to-thickness ratio (r1/t) of 8. (See Figure 1.1.)
1.36 Braced member
Member for which the transverse displacement of one end of the member relative to the other is effectively prevented.
1.3.7 Can
Implies a capability or possibility and refers to the ability of the user of the Standard, or to
a possibility that is available or that might occur.
1.3.8 Capacity design principles
Appropriate material standard design and detailing provisions which enable zones where post-elastic response is acceptable to be identified and detailed in a manner that ensures these zones are capable of accepting the inelastic demands placed upon them.
NOTE: All other zones are to be designed to ensure that all other undesirable inelastic response mechanisms are suppressed and detailed in a manner that the ultimate limit state horizontal deformations that they are expected to be subjected to, can be sustained without significant (e.g., greater than 20%) loss of load-carrying capacity after four complete cycles of loading.
1.3.9 Capacity reduction factor
A factor used to multiply the nominal capacity to obtain the design capacity.
1.3.10 Clinching
Structural fastening of two or more flat elements by single-point embossing or piercing without using additional material.AS/NZS 4600 pdf download.
