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?.

Aiec Panel Zone Shear The symbol representing the column cross-sectional area, A, has been changed to Ag, and its definition has been changed to represent the gross cross-sectional area of the member. Strength of Aisd in Flexure This section is new to the Specification. Dimensional Requirements Parts of this section have been reworded to improve clarity. The minimum height requirement for access holes has been changed from 1 in.
Compression Flange Local Buckling No changes have been made to this section.
Fillers in Welded Connections Section J5. The approximate second order analysis B1-B2 method has been moved from Chapter C. The Specification, however has put all these analysis requirements in one section.
Design Strength No changes have been made to this section. For open cross sections the minimum shear lag factor, U, has been changed from equal to or greater than 0.

Figures are aiscc bolted connections designed to bear, meeting the requirements of slip-critical connections. Design not Performed with Prismatic Properties. Field Welding The Specification specifically references wire brushing to assure weld quality for shop paints on surfaces adjacent to joints, if necessary.
Remember me on this computer. The variable used for the clear distance, wisc the direction of the force, between the edge of the hole and the edge of the adjacent hole or edge of the material, Lc, has been changed to lc.
Relative Bracing The symbol representing the required brace strength has been changed from Pbr to Prb. Residual Stress and Partial Yielding Effects The effect of residual stresses and partial yielding must be part of the inelastic analysis; this was not specified in the Specification. The effects of member strain should be included when aics Ip and Is for trusses and steel joists.
The first paragraph of Section M5. Which one should I aics Also, bolt bearing with short-slotted holes parallel to the direction of tension are to be assumed at the end of the slot. Inaccessible Surfaces No changes have been made to this section. It now only applies to A bolts when determining the nominal shear strength in bearing-type connections. Design for Serviceability was Section B3. Direct Bond Interaction This new section gives equations for force transfer in filled rectangular and round steel sections by direct bond interaction.
One such expansion is the 360-50 of three tables Tables N5. This was footnote [f] aiscc the Specification. The topics of quality control and quality assurance are now included in a new section. Design by Engineering Analysis It is now required that the load and resistance factor design method, in accordance with the provisions of Section B3. A statement has been added stating that the use of the first-order estimate of, Pr, is permitted in the B1 equation.
Localized Fire No changes have been made to this section. A paragraph has been added for the stability analysis of a structure using materials other than structural steel. Limit states need only be checked when connection geometry or loading is within the parameters given in the description of the limit state.
General Structural Integrity No changes have been made to this section. Applying Parameters Load 36-005.
Difference between AISC 9th ed. and 360-05/10
Anchorage to Concrete new section This section includes references to Chapter I for design of steel and concrete acting compositely and Chapter J for design of column bases and anchor rods. The classification for flexure remains 360–05 same while compression members are now classified as either slender or nonslender.
For beams, girders and trusses the supports shall be restrained against rotation unless analysis shows that restraint is not required. Limitations Parts of Section C2.

The content of this section have been moved from Appendix 7 in the Specification. Drain Holes No changes have been made to this section.
Steel Castings and Forgings No changes have been made to this section. Strain Compatibility Method No changes have been made to this section.
