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?.

Two new figures have been added for Case 2 examples, one is a single angle the other is a tee shape. Cross Section Section 1. Mechanical Properties at Elevated Temperatures The proportional limit at elevated temperatures, Fp Tis now defined in this section and it is calculated as a 360-005 to yield strength as specified in Table A- 4. Direct Modeling of Imperfections new Section The provisions in this section allow for the effects of initial imperfections to be accounted for directly by analysis.

The symbol representing the projected length of the overlapping branch on the chord, p, has been changed to lp.

Inspection of Welding Section M5. Shear connector detailing requirements have been moved to Section I6. Limitations Several new requirements have been added to Section I2. Limitations on Bolted and Welded Connections Slip-critical has been removed from the list of required joints in this section. The equation for Pe2 in the Specification has been changed as follows: The statement requiring crack inspections in accordance with ASTM E for hot-rolled shapes with a flange thickness greater than 2 in.

Strength The limit state of yielding is no longer applicable when determining the base material strength and the ajsc metal strength.

Stiffened Elements was Section B4. Several sub-sections have been moved here including, B4. Transverse Stiffeners The first limiting condition in Section G3.

Plug and Slot Welds J2. Tensile Strength In Equation D the 360-0 for effective edge distance, beff, has been changed to be. Additionally, the interaction equations of Section H1. Charpy V-notch results are not required when a non-heavy shape is welded to the face of a rolled heavy shape with complete joint penetration groove welds.

Flange Local Buckling No changes have been made to this section. These sections qualify as compact, noncompact or slender for both compression and flexure. These equations also incorporate the moment at the middle of the unbraced length, Mmid, and both M1 and Mmid are taken as positive when they cause compression in the 30-05 flange as M2.

A user note has been added to this section stating that there are no specific minimum or maximum tension requirements for snug-tight bolts and fully pretensioned bolts such as ASTM F or F are permitted unless specifically prohibited on design drawings.

Local Buckling No changes have been made to this sisc. Applies To Product s: Built-Up Beams No changes have been made to this section.

The approximate second order analysis B1-B2 method has been moved from Chapter C. For beams, girders and trusses the supports shall be restrained against rotation unless analysis shows that restraint is not required. The following table shows the changes that have been made to the element descriptions and the case numbering in this table. Also added is a statement that the approximate method of second-order analysis is permitted as an alternative to rigorous second-order analysis.

Design by Qualification Testing No changes have been made to this section. Weld Access Holes Beam cope provisions have been removed from this section.

Definitions of Parameters The symbol representing the bearing length of the load, measured parallel to the axis of the HSS member, N, has been changed to lb. Several new exceptions and limitations are given for the use of ACI Fillers in Bolted Connections A minimum value of 0.

A paragraph has been added to the beginning of this section that outlines the design basis for columns and beams with respect to unbraced length. Enter the email address you signed up with and we’ll email you a reset link.

Other provisions for thin fillers remain the same and have been reorganized in this section. These new equations are similar to Equations A and A from the Specification, but they now allow for Lpd to be explicitly calculated without determining whether reverse curvature or single curvature are present. The definition for U and any terms associated with that symbol are also tabulated there.

The classification for flexure remains the same while compression members are now classified as either slender or nonslender. The variable for the limiting laterally unbraced length for plastic analysis, Lpd, has been changed to the limiting laterally unbraced length for eligibility for moment redistribution in beams, Lm.

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.
