Tekla Tedds 2019 release notes

Steel simple connection design (EN1993)

• New calculation for the analysis & design of simple beam to beam and beam to column steel connections. The calculation checks for shear and tying design forces and will automatically size the connection for the specified beam sizes. In accordance with EN1993 and the national annexes for the UK, Ireland, Singapore, Malaysia, Finland, Norway, Sweden or the recommended Eurocode values.

RC pile cap design (EN1992/EN1997)

• New calculation for the design of pile caps supporting a single column with up to 9 piles. The column may be subject to axial compression or tension, shear loads and biaxial bending. Steel, concrete or timber piles can be defined with compression, tension and shear capacity. The calculation checks positive and negative bending in the pile cap, shear, column punching shear, pile punching shear, punching shear for pile pairs, and corner pile shear as appropriate. In accordance with EN1992, EN1997 and the national annex for the UK, Ireland, Singapore, Finland, Sweden, Norway or the recommended Eurocode values.

Timber joist design (EN1995)

• New calculation which checks the design of a solid timber or glulam joist subjected to uniformly distributed loads and a point load. Line loads can also be included at the end of cantilever spans. Permanent, imposed, snow and wind loads can be defined depending on the load duration selected. The joist may be either a simply supported single span or a continuous span beam. In accordance with EN1995 and the national annexes for the UK, Ireland, Singapore, Finland, Sweden, Norway or the recommended Eurocode values.

​Timber rafter design (EN1995)

• New calculation which checks the design of a solid timber or glulam rafter subjected to uniformly distributed loads and a point load. Permanent, imposed, snow and wind loads can be defined depending on the load duration selected. The rafter may be either a simply supported single span or a continuous span beam propped by purlins. In accordance with EN1995 and the national annexes for the UK, Ireland, Singapore, Finland, Sweden, Norway or the recommended Eurocode values.

​Rolling load analysis

• Enhanced calculation for the analysis of a continuous beam with unlimited spans and a load train which can include unlimited wheel point loads. A Eurocode version is included in addition to the British Standards version. The user interface has been significantly improved with all options available on a single dialog, preview results and moment, shear and deflection envelope diagrams. The output options have been enhanced to include a user defined title, user defined notes and geometry, moment, shear and deflection diagrams. The calculation can also be used with the Tedds batch design spread sheets to rapidly compare multiple design scenarios.

​Design rainfall (The Wallingford Procedure)

Infiltration system design (SUDS)

Stormwater attenuation design

Swale and filter strip design

Soakaway design (BRE digest 365/SUDS)

• Enhanced to include the option to extrapolate the 50 year and 100 year Z2 values to 200 years.

Batch desig​n

• Enhanced to allow the output for each design case to be saved to PDF or Microsoft Rich Text Format. Enhanced to include the option to select an existing example and have the fields automatically populated. New working examples for Rolling load analysis, Steel simple connection design (EN1993), Steel member design (EN1993), RC beam design (EN1992) and Timber member design (EN1995) are now included. A new option has been added to completely disable the user interface of a calculation if that calculation has a dedicated Calc API (Application Programming Interface), i.e. the calculation can be used to design check only with no manual user interaction. Refer to the calculation notes for specific calculations to determine whether they support a Calc API. If the user interface is completely disabled the calculation performance improves significantly, however the input data will not be validated in any way. An option has also been added to set the input variables in the user interface of the calculation to be read only thus preventing input which has been defined in the batch design work sheet from being subsequently amended in the user interface of the calculation.
