Tekla Tedds Engineering Library (June 2021)


UK and Asia

Timber member design (EN1995)

Enhanced to allow built up sections to be wider than they are deep.

Component calculations

Added a new folder to the Engineering Library for "Component calculations". A component calculation encapsulates a small engineering solution which can be easily reused by other calculations. They are typically used by calculations in the Tedds Engineering Library and can also be integrated in your own custom written calculations.

Component calculation: Steel section classification (EN1993)

Checks the section classification of carbon steel or stainless steel sections.

Component calculation: Steel section sketch

Creates a drawing of a Steel section profile which can then be used in the user interface or output of another calculation. Supports section types I, T, Channel, Hollow Circle, Hollow Rectangle, Angle, 2 Angles, 2 Angles (log leg), 2 Angles (short leg), Asymmetric I, Slimflor and Flats. The drawing can be customised to include dimensions and section properties as appropriate.

Other Updates

Batch design

Enhanced to include examples for carbon steel and stainless steel for the "Steel section classification (EN1993)" calculation component.
