SCIA Engineer provides for easy definition of commonly used types of welded cross-sections made of steel flats by offering the selection from a library of such cross-sections.
The procedure for insertion of a welded cross-section into a project is identical with the procedure for any other cross-section type; the user just have to specify the type in the type-selection dialogue, then choose the appropriate shape and size, and oversee or change the required parameters.
As for any other cross-section type, the sectional characteristics such as sectional area, moment of inertia, position of centroid, etc. are calculated automatically by the program. The user may input or modify other cross-section parameters such as material, name, etc.
In addition to the basic sectional characteristics, the program also calculates, designs and displays data such as:
shape of a wall stiffener,
diagram of warping lines,
diagram of shear stress distribution over the cross-section for a unit force acting in Y-direction,
diagram of shear stress distribution over the cross-section for a unit force acting in Z-direction,
centre lines of the cross-section.
Note: Some of the above mentioned data depend on the shape of the particular cross-section. Therefore, some of the values may not be available for some of the cross-section shapes.
Sample cross-sections
Note: The last two cross-sections (framed in the picture)have corrugated web. Therefore, their sectional characteristics differ from the first two cross-section.
