The following table shows the changes that have been made to the element descriptions and the case numbering in this table.
You may have already requested this item. A user note has been added stating the initial displacements should be similar in configuration to displacements caused by loading and buckling with magnitudes based on permissible construction tolerances given in the AISC Code of Standard Practice.
General Requirements This section combines the axial load transfer for both the encased and filled axially loaded composite members. SINGLE ANGLES There has been a statement added to this section stating if there is a moment about both principle axes with or without axial load, or of there is a moment along one principle axis with axial load the combined stress ratio shall be determined using Section H2. Alignment No changes have been made to this section.
36-05, Internet resource Document Type: Transverse Stiffeners The first limiting condition in Section G3. Nominal Strength of Composite Sections Added to this section is the statement that local buckling effects do not need to 630-05 considered for encased composite members. Additionally, the interaction equations of Section H1. A user note has been added stating that the imperfections considered are the locations of points of intersection of members caused by the out-of-plumbness of columns.
Material Limitations Structural steel has been included in the list for material limitations of this section. The first paragraph of Section M5.
Design by Engineering Analysis It is now required that the load and resistance factor design method, in accordance with the provisions of Section B3. A minimum size of reinforcement is given along with the maximum spacing of ties based on reinforcement size and least column dimension.

Detailing Requirements in Composite Components This section gives the provisions for the minimum cover, minimum and maximum spacing of steel headed stud anchors and maximum spacing of steel channel anchors for composite components. Design of Connections Added to this section is the statement that self-limiting inelastic deformations are permitted. Special Fasteners No changes have been made to this section. The channel shear connecter is now defined as a hot-rolled channel anchor.
Compressive Strength This section is reorganized to improved clarity. Placement of Welds and Bolts No changes have been made to this section. They include changes to the design provision for both compression and flexural members.
Compressive Strength The provisions of this section now specifically apply to axially loaded doubly symmetric encased composite members.
American Institute of Steel Construction. Additionally, the Specification incorporated former Section M4. Please enter recipient e-mail address es. Added is a statement that the available compressive strength need not be less than that of the bare steel member. Design for Fire Conditions was Section B3.
ANSI/AISC 360-05 – Specification for Structural Steel Buildings
In Equation F the cross-section monosymmetry parameter, Rm, has been removed along with the upper limit as follows, Specification: Reviews User-contributed reviews Add a review and share your thoughts with other readers. Unidentified Steel This section is expanded to include a statement that the use of unidentified steel shall be subject to the approval of 3360-05 engineer of record.
The organization of this chapter remains the same with the exception of Section M5 being relocated to Chapter N. Encased Composite Members I2. The symbol representing the projected length of the overlapping branch on the chord, p, has been changed to lp. Material Properties and Yield Criteria This section includes material properties and yield criteria that must be included in the inelastic analysis that were anzi specified in Sections 1.
The definition of the design wall thickness, t, has been added to this section. Added to this list includes stiffness reduction due to inelasticity and uncertainty in stiffness and strength. 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.
A user note has been added to this section stating that there are no specific minimum or maximum tension requirements for snug-tight 360-055 and fully pretensioned bolts such as ASTM F or F are permitted unless specifically prohibited on design drawings. Gross Area was Section B3. 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 Aiac K4.
The following equation has been added to this section: A user note is included referring to ACI for additional tie and spiral reinforcement requirements.
Unframed Ends of Beams and Girders No changes have been made to this section. Nuclear Applications was Section A1. The approximate second order analysis B1-B2 method has 36-005 moved from Chapter C. Compression Flange Yielding No changes have been made to nasi section. Design rules for T- Y- and cross-connections 630-05 branch axial load or bending are now included in the Specification.
You already recently rated this item. Flexural Strength New equations have been provided for the calculation of the nominal flexural strength for compact, noncompact and slender filled composite members. The limit states based on limiting deformations or yielding do not need to be considered for structural integrity requirements.
