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. Tensile Strength In Equation D the variable for effective edge distance, beff, has been changed to be. Design by Engineering Analysis It is now required that the load and resistance factor design method, in accordance with the provisions of Section B3.

Leg Local Buckling No changes have been made to this section. Built-Up Heavy Shapes No changes have been made to this section. Combination of Welds No changes have been made to this section. Cover Plates No changes have been made to this section. Restrained Construction No changes have been made to this section. Filled and Encased Composite Members The available shear strength of an encased composite member is now allowed to be calculated using the nominal shear strength of the steel section alone.

In addition to being used to asic shear in lap joints, fillet welds in holes or slots are now permitted to be used to resist loads perpendicular to the faying surface in lap joints.

The E-mail message field nasi required. Similar to Section N5. The footnote in the user note which gives the qualifications for a no decking condition has been removed. Where bolts have not been added to distribute the load in the filler for two or more fillers between connected parts, this variable is taken as 0.


The approximate second order analysis B1-B2 method has been moved from Chapter C. The following condition has been added to this section for compact members: The following equation has been added to this section: The pattern of initial displacement of points of intersection from their nominal locations shall be the maximum amount considered which causes the greatest destabilizing effect. A user note has been added Fy Fy to 3600-5 section stating that for double angles with web legs in compression the limit state of local buckling is checked using Section F General Structural Integrity No changes have been made to this section.

Excessive thermal expansion may cause the concrete to spall or crack and may cause excessive stress in the embedment anchors.

ANSI/AISC 360-05 Code check

The correct horizontal reaction at the base is found using a force equal to but opposite in direction to the notional loads applied at the base. The following table shows the changes that have been made to the element descriptions and case numbering in this table. Design for Corrosion Effects was Section B3. In Equation G, the variable, a, has been changed to b. For open cross sections the minimum shear lag factor, U, has been changed from equal to or greater than 0. Unbraced Length for Moment Redistribution new section The contents of this section have been moved from Appendix 1, Section 1.

Inspection of Welding Section M5.

The definitions of h and t have been added to this section. This appendix has been reorganized into three main sections.

ANSI/AISC Code check

A user note is included referring to ACI for additional tie and spiral reinforcement requirements. Remember me on this computer. Doubly and Singly Symmetric Members Subject to Flexure and Tension 360–05 term tensile strength has been changed to axial strength in the variable definitions.

The provision for when lateral bracing is attached to a stiffener has been removed. Added to this section is the statement that aiscc rational method that considers the effects listed in this section is permitted. Also available in print. Methods of Analysis 4.


American Institute of Steel Construction. Unbraced Length Section 1. In addition, the Specification added a paragraph on field welding of attachments to installed embedments in contact with concrete. Nondestructive Testing of Welded Joints N5.

Aidc user note has been added to this section stating that the strength of a bolt group be taken as the sum of the effective strengths of the individual fasteners, where the effective strength of an individual fastener may be taken as the lesser of the fastener shear strength based on the provisions of this section or that of the bearing strength ansl the bolt hole from the provisions of Section J3.

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

This section has been reorganized to improve clarity. 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.

The E-mail Address es field is required. Concrete and Steel Reinforcement In the Specification the provisions of qisc ACI are applied in the absence of an applicable building code.

You already recently rated this item. The resistance factor for LRFD and safety anxi for ASD are given for calculating the nominal shear strength of the reinforced concrete portion alone or the reinforced concrete with the steel section, they are as follows: The organization of this chapter remains the same with the exception of Section M5 being relocated to Chapter N.

In Equation F the variable, bf, has been changed to b. The organization of this appendix remains the same.
