This appendix has been reorganized into three main sections. Difference between AISC 9th ed. Analysis will cover all gravity xisc and applied loads that may influence the stability of the structure.

Filler Metal Requirements No changes have been made to this section. Shear connector detailing requirements have been moved to Section I6. Direct Bond Interaction This new section gives equations for force transfer in filled rectangular and round steel sections by direct bond interaction. Strength of Elements in Compression No changes have been made to this section. Serviceability and Strength check for the same load combination.

Equation K was Equation K in the Specificationwhich is used to calculate the total effective weld length for welds on both sides of the transverse plate for rectangular HSS, has been moved to Table K4. A definition for variables, Iyc and hc, have been added to this section.

Field Painting No changes have been made to this section. Gross Area was Section B3. Web Local Buckling No changes have been made to this section. The statement requiring crack inspections in accordance with ASTM E for hot-rolled shapes with a flange thickness greater than 2 in.

The definitions for Qf are now located in Table K1. The equation for the second limiting condition has been changed as follows: This section also specifies that the quality assurance agency shall submit inspection reports and nondestructive testing reports to the AHJ, EOR or owner as well as the fabricator and erector. Limitations The first two limitations presented in this section are equivalent to those presented in Section 7.

Other provisions for thin fillers remain the same and have been reorganized in this section. Initial out-of-straightness of members is addressed in Chapter E for compression members and is not considered explicitly in analysis.

Figures are for bolted connections designed to bear, meeting the requirements of slip-critical connections. The bracing which defines the unbraced length will have stiffness sufficient to control member movement at braced points, which is covered in Appendix 6. In addition, this section now outlines the basic procedure for performing an inelastic analysis and introduces the other sections in the appendix.

As such, these limitations have been moved from Section C2. The paragraph referencing Section J3. The strength of the bolt group is the sum of the effective strengths of the individual fasteners, where the effective strength of an individual fastener is the lesser of the fastener shear strength per Section J3.

Including Deflection Check as Criteria. Required Strengths The requirements listed in this section additional lateral load, Ni, and the nonsway amplification of beam-column moments have been moved from Section C2. Combination of Welds No changes have been made to this section.

The material in Section E5 c has been moved to Section E5 with the exception of the specific examples of different end conditions, requiring the use of Chapter H provisions, which has been removed. Nodal Bracing The symbol representing the required strength of nodal bracing, Mbr, has been changed to Mrb.

Fillers in Bolted Connections A minimum value of 0.

The chapter organization remains the same except for the addition of Section K4. Zisc Length Section 1. Diaphragms and Collectors new section References to applicable sections for designing diaphragm and collector elements have been added in this new section.

Several new exceptions and limitations are given for the use of ACI Lateral Bracing This section has been reorganized to wisc clarity. The provision for clear cover to reinforcing steel has been changed from a minimum 1.

ANSI/AISC 360-05 – Specification for Structural Steel Buildings

The available shear strength for filled composite members is now allowed to be calculated based on the nominal shear strength of the steel section plus the nominal shear strength of the reinforcing steel.

Axial Force This section is based on Aiisc 1.

A user note has been added stating that torsional bracing can be provided with a moment-connected beam, cross frame, or other diaphragm element. The distribution of at aics 2.

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 user iasc from section E6.

3360-05 Strength at Bolt Holes A user note has been added to this section: Dimensional Requirements Parts of this section have been reworded to improve clarity.

It is specified in this section that the effective length factor, K, of all members shall be taken as unity. Enter the email address you signed up with and we’ll email you a reset link.
