دانلود کتاب سازه های فولادی – AS 4100:2020

This Standard was prepared by the Standards Australia Committee BD-001, Steel Structures, to supersede AS 4100—1998.
The objective of this Standard is to provide designers of steel structures with specifications for steel structural members used for load-carrying purposes in buildings and other structures.
Major changes to the 1998 edition include the following:
(a) Reference to the “construction specification” (as the document containing the particular design data and details to be provided) as one deliverable from the design process. A definition of the construction specification consistent with that in AS/NZS 5131 has also been provided (Clauses 1.3.16 and 1.6.2).
(b) Introduction of the definition of “construction category” and an informative appendix providing guidance on selection of the appropriate construction category, both consistent with AS/NZS 5131 (Clauses 1.3.15 and 1.7.2, and Appendix L).
(c) Definition and description of “architecturally exposed structural steelwork” (AESS) (Clauses 1.3.3 and 1.7.3)
(d) Definition and treatment of “lamellar tearing” consistent with AS/NZS 1554.1 (Clauses 1.3.40 and 3.8, and Appendix M).
(e) Alignment with AS/NZS 5100.6:2017 (various clauses).
(f) Referencing of AS/NZS 5131:2016 for the majority of requirements in the fabrication and erection sections of this Standard (Sections 14 and 15).
(g) Alignment with AS/NZS 1252.1:2016, which includes introduction of an “alternative bolt assembly type” to EN 14399-3 System HR for grade 8.8 bolts and an “additional bolt assembly type” to EN 14399-3 System HR for grade 10.9 bolts. The Australian Steel Institute (ASI), Technical Note TN-001, High strength structural bolt assemblies to AS/NZS 1252:2016, provides background and basis for the revision to AS/NZS 1252:1996 (Clauses 9.1.6, 9.3, 15.2).
(h) New specification of geometrical tolerances for fabrication and erection aligned with AS/NZS 5131 (Clauses 14.4 and 15.3).
(i) New Appendix K “Statistical data”, aligned with AS/NZS 5100.6.
(j) Inclusion of shear modulus G at elevated temperature in Clause 12.4.2 and a new Clause 12.4.3, Slenderness at elevated temperature
