STEEL STANDARDS

The steel standards with which the verification and optimization calculations are made must be selected. The user must define the combined loads for verification and design computations. The combined loads are automatically generated when you use the Steel Calculator.

Canadian Standards

CSA S16-01, CSA S16-09 and CSA S16-14. The CSA S136 standard is considered when the CSA S16 is not applicable. It occurs for Class 4 sections (slender sections)

American Standards

Limit States Design of Steel Structures AISC 360-16 (LRFD) AISC 360-10 (LRFD) and AISC-LRFD-99

Allowable Stress Design AISC 360-16 (ASD), AISC 360-10 (ASD) and AISC-ASD-89

European Standard

Eurocode 3

Indian Standard IS 800-2007

**CSA S16-01, CSA S16-09 and CSA S16-14 standards**

Axial Compression: The factored axial compressive resistance of a member is calculated according to clause 13.3.

Bending: The bending strength (Mr) can be evaluated for beams when the compression flange has continuous lateral support or intermediate lateral supports. The resistance is calculated according to clauses 13.5 and 13.6.

Axial Compression and Bending: The resistance requirements of members subjected to both axial compression and bending are defined in clause 13.8.

Axial Tension and Bending: The resistance requirements of members subjected to both axial tension and bending are defined in clauses 13.2 and 13.9. Tension members are designed on the basis of net area as described in clause 12.3 of standard.

Shear: The factored shear resistance (Vr) developed by the web of a flexure member subjected to shear is defined in clause 13.4. For 2D models, the shear is given in only one plane. For 3D models, it is calculated along the y and z axes of the member’s internal coordinates normal to the neutral x axis.

**AISC 360-16 and AISC 360-10 (LRFD and ASD) standards**

Axial Compression: The factored axial compressive resistance of a member is calculated according to clauses E1 to E4, E6 and E7.

Bending: The bending strength (Mr) can be evaluated for beams when the compression flange has continuous lateral support or intermediate lateral supports. The resistance is calculated according to clauses F1 to F11 and B4. The strength of single angle limit states is calculated according to principal axes.

Axial Compression and Bending: The resistance requirements of members subjected to both axial compression and bending are defined in clause H1.1, H2 and H3.

Axial Tension and Bending: The resistance requirements of members subjected to both axial tension and bending are defined in clause H1.2, H2 and H3. Tension members are designed on the basis of clauses D1 and D2. The bending strength is evaluated with respect of the corresponding lateral support.

Shear: The factored shear resistance (Vr) developed by the web of a flexure member subjected to shear is defined in clauses G1, G2.1 and G4 to G6. For 2D models, the shear is given in only one plane. For 3D models, it is calculated along the y and z axes of the member’s internal coordinates normal to the neutral x axis.

**EC3 standard**

Axial Compression: The factored axial compressive resistance of a member is calculated according to EN 1993-1-1:2005 clauses 6.2.4 and 6.3.1

Bending: The bending strength (Mr) can be evaluated for beams when the compression flange has continuous lateral support or intermediate lateral supports. The resistance is calculated according to EN 1993-1-1:2005 clauses 6.2.5 and 6.3.2. The bending resistance is reduced depending on the shear forces applied (EN 1993-1-1:2005 clause 6.2.8).

Shear: The factored shear resistance (Vr) developed by the web of a flexure member subjected to shear is defined in EN 1993-1-1:2005 clause 6.2.6 and EN 1993-1-5:2006 clause 5.3.

**IS 800 standard**

Axial Compression: The factored axial compressive resistance of a member (Cr) is calculated according to clause 7.1.

Bending: The bending strength (Mr) can be evaluated for beams when the compression flange has continuous lateral support or intermediate lateral supports. The resistance is calculated according to clauses 8.2.1 and 8.2.2. The bending resistance is reduced depending on the shear forces applied (clause 9.2).

**Predefined models include:**

– Simple beams with common support conditions.

– Continuous beams with up to four spans.

– Cantilever beams

– Gerber beams

– Columns with offset loads with common support conditions.

• Standard CISC, AISC or European sections or parametric section shapes libraries created with the GSE software.

• Sections can be selected by the user or by the program.

• Dead, live, wind, snow and seismic loads.

• Required inputs : section types, basic loads, geometric limits and design parameters.

• To account for steel shape availability, the program can also perform verification on all section shapes of a given category.
