SDC Verifier

Tools

The following tools are available:

Export Model to File - creates a text file with materials, properties, nodes and elements ids without a model data. The file is used to debug user problems without having the customer model.

Free Edge

Free Edge Tool automatically finds free edges between the elements.

To run Free Edge execute Tools - Free Edge from the main menu. Alternatively, use the Tools context menu.

Free Edge tool:

Press Find and the table will be filled with the groups of elements that have Free Edges.

Press All to select all groups from the list and None - to deselect;

Press to display only groups of elements.

Press to highlight the selected groups of elements.

- export selected groups to Ansys;

- export selected groups to components.

Moment Ratio

Moment Ratio calculates a moment ratio on the ends of a member found by the Beam Member Finder.

It is used in the moment reduction factors calculations in the following standards: API 2A RP (table D.3-1), ISO 19902 (table 13.5-1) and Norsok N004 (table 6-2):

And moment reduction factors according to Eurocode3 (table 6.6):

Cb lateral-torsional buckling modification factor for AISC360-10 is calculated for Moment Ratio Torsional Y and Z:

Cb lateral-torsional buckling modification factor for AISC ASD 89 (Section F1.3) is calculated for Moment Ratio Torsional Y and Z:

Four moment ratio tools are created by default for length y, length z and length torsional members with Y/Z moment ratios.

To display the Moment Ratio execute from the context menu Edit.

The following dialog will be displayed:

M1(end min) and M2(end max) - the bending moment on the ends of the beam member.

M1/M2 - the moment ratio between the ends of the beam member..

Min/Max - the minimum/maximum bending moment over the full member.

Kc - the reduction factor according to Eurocode3, Part 1-1 Table 6.6.

Cb(Aisc89) - the lateral-torsional buckling modification factor according to AISC ASD 89.

Cb(Aisc2010) - the lateral-torsional buckling modification factor according to AISC360-10.

Select Load using Selector Control.

- plot moment ratios (M1/M2) for the selected members;

- plot ids for the selected members;

- plot Cm Type for the selected members. Cm type can be changed in Beam Member Finder:

- plot Kc factor;

- plot Cb factor for AISC ASD 89 or AISC 360-10;

- highlight the selected beam members;

- preview only selected beam members.

For the selected member the bending moment diagram is displayed. End moments, Min/Max over the full member are shown with labels:

Example: Calculation of the reduction moment factors Cm according to ISO 19902:

Weld Summation Tool

Weld Summation tool is used to summarize Grid Point Forces over welds. The results of the tool are used in the Weld Checks.

Select Load and press Fill Table to display force summation for all welded parts.

To display force/moment define direction in Plot group box and press Plot.

- highlight selected weld parts;

- preview selected weld parts;

- display colored weld plot with weld ids as labels;

- detailed information about single weld part, including results for each element/node.

- display forces as labels for selected weld parts;

- display moments as labels for selected weld parts.

Forces are summarized over the weld nodes (41 - 47) using elements only from the respective weld part (101 - 126).

Weld Stresses

Stresses due to forces are calculated using the weld area, and due to moments using the inertia of the full weld.

Note: Weld inertia is calculated assuming that effective weld section is horizontal and weld is double-symmetric.

Stresses are rotated into weld X, Y and XY directions and translated to points on the weld face at the each end of the weld (T1, T2, B1 and B2).

Following matrix of rotation is used:

- Von Mises stress at certain point. Stress is used in calculations of weld capacity in design standards.
