CYPECAD and Metal 3D

• Polygonal limits for footings
  The use of polygonal limits for footings has been improved. If a limit has been introduced incorrectly, the program allows for the footing to be designed, but without taking it into account. The reason why it has not been possible to adapt the design to the introduced limits is displayed in the check report of the affected footing.
  
  The reasons may include:
  • The limit that has been introduced cuts through a column.
  • The limit that has been introduced intersects the footing but does not divide it.
  • The limit is lies completely within the inside of the footing.
  • As there are no reinforcement starts present at the footing, the effective outline cannot be calculated.
  • The limit divides the footing without the reinforcement starts lying in a single part of the footing.
  • Tapered footings are not affected by the introduced limits.
  The footing check reports can be visualised using different options:
  • In CYPECAD
    • Beam Definition or Results tab > Foundation > Code check errors > Select footing
    • Beam Definition or Results tab > Foundation > Foundation elements > Edit icon > Select footing > Code checks button or Design button.
  •  In Metal 3D
    • Foundation tab > Analysis > Check > Select footing
    • Foundation tab > Foundation elements > Select footing > Check button or Design button.
• Export to TEKLA® STRUCTURES
  • The mesh generation exported to TEKLA® STRUCTURES has been optimised.
    

Portal Frame Generator

• Isolated roofs
  Wind pressure calculations have been implemented for isolated roofs (shelter type structures) for the codes indicated below:
  • CTE DB SE-AE (Spain). Código Técnico de la Edificación. Documento Básico Seguridad Estructural - Acciones en la Edificación.
  • Eurocode (generic and national annexes). EN 1991-1-4 (2005). Eurocode 1: Actions on structures. Parte 1-4: General actions – Wind actions.
  • DIN 1055-4:2005-03. (Germany). Einwirkungen auf Tragwerke - Teil 4: Windlasten.
  • R.N.V.99 D.T.R. C 2-4.7. (Algeria)
• Wind load exportation to Metal 3D using the CIRSOC 102-1984 code (Argentina)
  As of the 2011.c version, the wind loads calculated by the Portal Frame Generator are exported to Metal 3D as surface loads.
