Profile Library cross-sections

Hot-rolled and cold-formed cross-sections made of steel are cross-sections manufactured in specialised factories. In SCIA Engineer whenever the user wants to use a hot-rolled or cold-formed steel cross-section, s/he may select appropriate shape and size from the integrated library of industrially manufactured cross-sections. All sectional characteristics are automatically read into the program and the user is not forced to take care of anything related to the section and its parameters and characteristics.

The procedure for insertion of a rolled 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.

By default, all the sectional characteristics of a rolled or formed cross-section are automatically imported into SCIA Engineer the moment the user makes a selection of required shape and size in the integrated cross-section library. If required, the user may specify the non-numerical parameters such as name, colour, material, etc. In addition to the basic sectional characteristics, the program also calculates 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.

The table below shows diagrams of the above-mentioned sectional characteristics for an I-beam.

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. E.g. the shape of stiffener is not provided for angles, or no additional parameters are available for bars, etc.
