Specification for Structural Steel Buildings (ANSI/AISC ) – March 9, Specification for Structural Steel Buildings (ANSI/AISC ). Note: Although the ANSI/AISC version of the code officially replaces the ANSI/AISC code, this latter remains available in the. You want to design steel members according American code ANSI-AISC Is it available in Autodesk Robot Structural Analysis?.

Proportioning Limits for I-Shaped Members The proportion limits of I-shaped 30-05 with slender webs have been changed as follow: The variable for the area of adequately developed longitudinal reinforcing steel within the effective width of the concrete, Ar, has been changed to Asr.
Bolts are permitted to be installed to the snug-tight condition when used in bearing type connections, except as noted in Section E6 or Section J1.
Definitions of Parameters No changes have been aiisc to this section. Case 8 is expanded to include double angles. Tensile Strength No changes have been made to this section. Cover Plates No changes have been made to this section.
Also added is a statement that the approximate method of second-order analysis is permitted as an alternative to rigorous second-order analysis. The design requirements in Section J4. The definitions for Qf are now located in Table K3. The width-to-thickness ratios for local buckling are now contained in Table I1. Strength of Steel Headed Stud Anchors for Interaction of Shear and Tension in Composite Components This section covers the nominal strength for interaction between shear and tension for a steel headed stud anchor.
Mixed Weld Metal No changes have been made to this section. Unstiffened Elements was Section B4. A user note has been added stating that AWS C4. Filled Composite Members The provisions for steel anchor detailing for filled composite members have been moved from Section I2.

Limit States Several additions have been made to this section for completeness of structural integrity requirements for connections. Noncompact and slender members are now allowed by the provisions without justification by testing or analysis.
Strength Requirements and Deformation Limits No changes have been made to this section. The organization of this appendix remains the same, except that title of Section 3. Web Sidesway Buckling In Equations J and J, the symbol representing the largest laterally unbraced length along either flange at the point of load, l, has been changed to Lb.
Net Area was Section B3. Lateral-Torsional Buckling A user note has been added stating that Equations F and F in the Specification produce identical solutions as the equations used in past editions of the LRFD Specification but are similar in appearance to the equations used for singularly symmetric sections.
Limitations The minimum length requirements for fillet welds designed on the basis of strength have been changed to incorporate the actual length of the weld instead of its effective length.

Compression Members with Bearing Joints The following sentence has been added to improve clarity: Field Painting No changes have been made to this section. Field Welding The Specification specifically references wire brushing to assure weld quality for shop paints on surfaces adjacent to joints, if necessary.
The user note referencing Section J3. The alternate lesser value of U, based on the effect of eccentricity, has been removed.
Fillers in Welded Connections Section Aic. The provision that higher strength materials are permitted when justified by testing or analysis has been removed. Diaphragms and Collectors new section References to applicable sections for designing diaphragm and collector elements have been added in this new section.
zisc The definitions of h and t have been added to this section. A user note has been added stating if bending is about the minor axis, only the limit states of yielding and leg local buckling apply. The organization of this chapter remains the same with the exception of Section M5 being relocated to Chapter N.
