The topics of quality control and quality assurance are now included in a new section.
This section now references Appendix 7 in addition to Chapter C, for the determination of the effective length factor, K. When a rolled heavy shape is welded to the surface of another shape using groove welds the Charpy V-notch requirement 306-05 applies to the shape with the weld metal fused through the cross section.
Noncompact and slender members are now aosc by the provisions without justification by testing or analysis. Nodal Bracing No changes have been made to this section. The subsections covering the strength, number and placement and spacing or steel headed stud anchors have been moved to Section I8.
Effective Width No changes have been made to this section. Remember me on this computer. Web Local Buckling No changes have been made to this section. Local Buckling No changes have been made to this section.

The channel shear connecter is now defined as a hot-rolled channel anchor. The ratios aisx limits for filled composite members are located in Tables I1. Bolted Construction Water jet cut holes are now permitted. Also included in this section are the requirements for the quality assurance personnel and the documents that are used. Proportioning Limits for I-Shaped Members The proportion limits of I-shaped members with slender webs have been changed as follow: Tensile Strength Aisd Equation D the variable for effective edge distance, beff, has been changed to be.
The reference to Table B4.
The definitions for Qf are now located in Table K2. The classification for flexure remains the same while compression members are aiac classified as either slender or nonslender. As such, these limitations have been moved from Section C2.
Required Number of Steel Anchors No changes have been made in this section. The references to Sections D3.
Other provisions for thin fillers remain the same and have been reorganized in this section. You should refer to the individual codes for more details. Block Shear Strength No changes have been made to this section.
Stability and Connections The title of this section has been renamed from Bracing.

Two zisc figures have been added for Case 2 examples, 630-05 is a single angle the other is a tee shape. The following equation has been added to this section: The LRFD resistance factor and ASD safety factor if steel anchors are provided using the plastic stress distribution on the composite section or strain compatibility methods have been changed as follows: In Equation F the variable for flange thickness, t, has been changed to tf.
SCOPE The scope of the Specification has been expanded by including systems with structural steel acting compositely with reinforced concrete. Required Strengths Parts of Section C2. Quality Control This new section references Sections N5.
The definitions of h and t have been added to this section. A statement that the available compressive strength need not be less than that of the bare steel member has been added. Design-Basis Fire No changes have been made to this section.
