1 Tutorial API A RP - July version 5.0

2 Content In this tutorial, API A RP Beam Design Checks are reviewed in details. A beam model of a steel frame has been used as a start FEM model. Beam member finder was used to recognize beam member length in 3 directions. The report was generated with the help of report designer.

3 Launch SDC Verifier Open in Ansys Workbench AISC360.wbpz Double Click on or in context menu click Edit 3

4 Predefined project This tutorial uses project with predefined boundary condition, load combinations and load group. The model contains only beam elements of the following types: I-Beam, Circular and Rectangular Tubes 4

Explanation of Joints Joint location where different beam members connect. They are used to recognize beam member length by Beam Member Finder Tool.

5 Explanation of Joints Joint location where different beam members connect. They are used to recognize beam member length by Beam Member Finder Tool. There are 6 types of Joints: D Joint beam members that lie on the curve but with different properties; D Joint beam members connected in one plane; 3D Joint beam members connected in space; Free Joint node which belongs only to one element (free); Beam-Plate Joint beam member connected to plates (perpendicularly); User Defined; 5

Joint Recognition Execute Edit from Joints context

Default option: Keep only modified remove all joints

6 Joint Recognition Execute Edit from Joints context menu Press Find. When performing the joint recognition there are 3 options for existing joints. Default option: Keep only modified remove all joints except edited by user. Keep all existing options should be used when additional elements were added to the model. 6

Cm reduction factors Cmy and Cmz reduction factors are used in combined axial and bending check. API RP A description: By default Cm Type is equal to A = 0.85 for all members.

12 Cm reduction factors Cmy and Cmz reduction factors are used in combined axial and bending check. API RP A description: By default Cm Type is equal to A = 0.85 for all members. It is possible to modify Cm Type for selected members: In SDC Verifier B = minimum from (b) and (c) Cmy and Cmz factors for ISO 990 can be found in the Table 3.5- and are used in the formula Cmy and Cmz factors for Norsok N004 Rev3 can be found in the Table 6- and are used in the formula 6.7

16 Define Material Characteristics Press to set the material yield stress and tensile strength Select All Materials (Ctrl+A) 3 Tensile Strength: 360e6 4 Yield Stress: 40e6 5 6 Press Set Press OK

To validate this condition, all dimensions should be converted to proper units in SDC Verifier.

17 Unit System API RP A Standard is applicable to stiffened and unstiffened cylinders having t >= 6mm, D / t < 300 and Yield Stress < 44 MPa. To validate this condition, all dimensions should be converted to proper units in SDC Verifier. MmKS (Millimeter/Kg/Second) unit system is used. To preview measurement units press In case the standard cannot perform verification of the model the results will display the value =
