API RP 2A-LRFD Members (1^st, 1993)

API RP 2A-LRFD checks the structural strength and stability requirements for steel cylindrical elements. Sections D (Cylindrical Member Design) and E (Connections) are implemented.

This standard is applied to the cylindrical members with the Thickness ≥ 6mm, ratio D / t < 300 and Yield < 414 MPa.

To add the Standard execute Standards - Main - API - API RP 2A-LRFD Members (1^st, 1993) from the ribbon:

Press to Set Standard Custom Settings

Safety Factors are set to Standard default values. It is not necessary to change them.

According to the calculation procedure, Beam Length for Y and Z direction is required. Data from Beam Member Finder is used automatically. If beam members are not recognized press .

Standard uses material data (Yield/Tensile) in calculations. Wizard checks if the values are defined for all materials.

It is possible to use API RP 2A-LRFD Members (1st, 1993) in combination with AISC 360-10 Members (14^th, 2010) standard. Set option Use AISC 360-10 for non-tubular shapes checked to use the standard for non-tubular elements. Press to define settings.

Note: If the AISC 360-10 is included - 3 standards will be created:

• API RP 2A-LRFD - circular tubes are calculated according to API LRFD;
• AISC 360-10 - all supported shapes are calculated according to AISC 360-10;
• AISC and API - combined standard where results for circular tubes are taken from API RP 2A-LRFD and results for other supported shapes - according to AISC 360-10.
