The most important requirement for structures is safety. To avoid an incident with construction collapse it should be verified according to a standard.
Perform checking according to standard is the quite complicated procedure. Besides the huge amount of rules to calculate (which depend on different shapes, materials, and other criteria) additional structure characteristics should be defined:
- For Beam Buckling – beam buckling length;
- For Plate Buckling – plate width, length, and direction;
- For Fatigue – welds classifications.
To define these characteristics manually is possible only for small models, but still is time-consuming. For big models like vessels, it is not possible. For example, in ship models where 100-200 thousands of plates to be checked using Plate Buckling DNV 2010 standard.
We believe that define characteristics routines can be automated. For that purpose, SDC Verifier implements a set of Recognition Tools: Joint Finder, Beam Member Finder, Panel Finder and Weld Finder.
Joint Finder recognizes types of joints (1D, 2DY, 2DZ, 3D, etc.) which are used to find beam member lengths and connections for Joint Check.
Beam Member Finder
Beam Member Finder recognizes beam buckling length in Y, Z and Torsional directions.
Plate buckling checks calculations are based on plate dimensions from Panel Finder tool. According to standard stresses into plate direction should be checked (which is automatically translated by buckling check).
Colored plots with labels (dimensions) make easy to preview tool results:
To perform Fatigue Check it is necessary to define Weld Type. It has an influence on Allowable Fatigue Stress.
With the weld finder, it becomes very easy to set the different weld type for the locations without weld, with weld (perpendicular K2 and parallel K1 to the weld) and for the intersections K2 all directions.
