The E-mail Address es you entered is are not in a valid format. Design for Fatigue was Section B3.
This table is similar to the flexural member selection table, Table User Note F1. The length of xnsi shear connector, Lc, has been changed to the length of channel anchor, la. Localized Fire No changes have been made to this section.
Definitions of Parameters No changes have been made to this section. The distribution has changed from at least 2. Citations are based on reference standards. Load Transfer This section now refers to Section I6 for load transfer requirements for encased composite members. Limitations Filled composite sections are now classified for local buckling using the limiting width-to-thickness ratios in Table I1. Cambering, Curving and Straightening Ans changes have been made to this section.
Adjustments to Stiffness new section This section has been moved from Appendix 7, Section 7. This chapter replaces Section M5 of the Specification. Simple Connections The provisions for permitting inelastic rotation of a connection have been removed from this section. Shear Strength of Steel Headed Stud Anchors in Composite Components This section covers aixc shear strength of a steel headed stud anchor when concrete breakout is not an applicable limit state.
Block Shear Strength No changes have been made to this section.
The variable for the area of adequately developed longitudinal reinforcing steel within the effective width of the concrete, Ar, has been changed to Asr. These provisions now apply to filled members. The content of this section have been moved from Appendix 7 in the Specification. Steel, Structural — Specifications.
Limitations Several new requirements have been added to Section I2. Methods of Analysis 4. One such expansion is the addition of three tables Tables N5. Maximum Spacing and Edge Distance A user note has been added to this section stating that dimensions which are listed just before the user note do not apply to elements consisting of two shapes in continuous contact.
New figures are included in the Examples column, which now include a larger number of applicable sections. Net Area was Section B3. Classification of Sections for Local Buckling was section B4 The local buckling classifications for members have been separated for flexure and compression. These sections qualify as compact, noncompact or slender for both compression and flexure. Positive Flexural Strength No changes have been made to this section.
The footnote in the user note which gives the qualifications for a no decking condition has been removed. The references to Sections D3.
Limitations Parts of Section C2. The approximate second order analysis B1-B2 method has been moved from Chapter C.

It now only applies to A bolts when determining the nominal shear strength in bearing-type connections. The width-to-thickness ratios for local buckling are now contained in Table I1.
It also states when NDT may be performed by approved fabricators. This section also specifies that reducing the rate of ultrasonic testing is prohibited. The web plate shear buckling coefficient equation for webs with transverse stiffeners has been given the equation number G Where bolts have not been added to distribute the load in the filler for two or more fillers xisc connected parts, this variable is taken as 0.
Axial Force This section is based on Sections 1. A minimum size of reinforcement is given along with the maximum spacing of ties based on reinforcement size and least column dimension. Available Strengths Sections C1.
ANSI/AISC 360-05 Code check
The following table lists the changes per case. Compression Joints No changes have been made to this section. Inaccessible Surfaces No changes have been made to this section. Anchor Rods and Threaded Rods No changes have been made to this section. Continuous Bracing This section has been reorganized to improve clarity.
A user note has been added stating that AWS C4.
