Material Properties and Yield Criteria This section includes material properties and yield criteria that must be included in the inelastic analysis that were previously specified in Sections 1. Bolts in Combination with Welds No changes have been made to this section. These new equations are similar to Equations A and A from the Specification, but they now allow for Lpd to be explicitly calculated without determining whether reverse curvature or single curvature are present. Fillers in Welded Connections Section J5. They include changes to the design provision for both compression and flexural members.

Two new user notes have been added to the Chapter K preamble: The variable for the factor to be multiplied to the available slip resistance per bolt, ks, has been changed to ksc.
Design by Qualification Testing No changes have been made to this aisc 360-05. Effective Width No changes have been made to aiwc section.

The organization of this chapter remains the same with the exception of Section M5 being relocated to Chapter N. Planing of Edges Aisc 360-05 changes have been made to this section. Effective 360-055 No changes have been made to this section. Required Strength The reference to the provisions in Appendix 1 for moment redistribution in continuous beams has been removed because this topic has been moved into this chapter.
It is specified in this section that the effective length factor, K, of all members shall be taken as unity. When determining the equation for the web plate shear buckling coefficient, the term unstiffened web has been changed to web without transverse stiffeners. Drain Holes No 360-005 have been made to this section.
The definition of the snug-tight condition has been simplified to the tightness aisc 360-05 to bring the connected plies into aic contact.
design steel according to AISC 360-05 using effective length method
Negative Flexural Strength No changes have been made to this section. Alsc In Sign Up. Applies To Product s: A-have been reformatted into a text description and moved into Section C2. A user note has been added to this section stating that the strength of a bolt group be taken as the aics 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 at qisc bolt hole from the provisions of Section J3.
The list has been changed so component and connection deformations are now categorized under all other deformations that aisc 360-05 to the displacement of the structure. Changing units for design as per Aisc 360-05 code. Thermal Elongation No changes have been made to this section. Welded Construction No changes have been made to this section.
Limitations Parts of Section C2.
Enter the email address you signed up with and we’ll email aisc 360-05 a reset link. The equation for Pe2 in the Specification has been changed as follows: Contact Surfaces No changes have been made to this section.
Cross Section Section 1. Quality assurance is provided by others when required by the authority having jurisdiction AHJpurchaser, owner or engineer of record EOR. Required Strengths Parts of Section C2.
Iasc user note has been added stating that 3660-05 notional loads can create additional fictitious base shears and overturning moments. Consideration of Initial Imperfections new section The effects of aisc 360-05 imperfections can be accounted for using either direct modeling or the use of notional loads covered previously in Appendix 7, Section 7.
The conditions under which a single hardened washer conforming to ASTM F shall be used in lieu of the standard washer and its associated user note have been moved to Section J3. The strength of the aisc 360-05 group is the sum of the effective aksc of the individual fasteners, where the effective strength of an individual fastener is the lesser of the fastener shear strength per Section J3. Block Shear Strength No changes have been made to this section. Residual Stress and Partial Yielding Effects The zisc of residual stresses and partial yielding must be part of the inelastic analysis; this was not specified in the Specification.
Adjustments to Stiffness new section This section has been moved from Appendix 7, Section 7. Figures are for slip-critical bolted connections. Compression Members with Bearing Joints The aisc 360-05 sentence has been added to improve clarity:
