3D results – Displacements & Stresses

SCIA Engineer 14.0 brings the presentation of results to a new level: 3D!

Displacements and stresses can now be displayed on the 3D rendered surface of columns and beams. On top of that, the results may be projected on the initial as well as the deformed structure. This feature provides even better insight into the global behaviour of the structure.

The 3D results are accessible at the top of the Results service:

 

3D displacements

Available values are:

  • ux, uy, uz: displacements of fibres, in the member local co-ordinate system
  • fix, fiy, fiz: rotations of fibres, in the member local co-ordinate system
  • Uglobal: resultant displacement of fibres, i.e. Uglobal = √(ux²+uy²+uz²)

 

3D stresses

Available values are:

  • σx: normal stress, perpendicular to the section plane
  • τxy, τxz: orthogonal shear stresses, in the principal axes of the cross-section, resulting from Vy, Vz and Mx
  • τxs = √(τxy² + τxz²)

These 3D results may be displayed on the original structure or on the deformed structure of the members.

When the ‘Deformed structure’ is selected, together with the envelope combination or a result class, also the type of ‘Member deformation’ needs to be selected:

  • For member maximum: The rendered surface is displayed as it deforms under the load combination that causes the extreme value of the selected magnitude on the member. The evaluation is thus executed for each member separately! For every member the extreme may be caused by another critical combination, therefore discontinuities in connecting nodes may occur.
  • For global maximum: The rendered surface is displayed as it deforms under the load combination that causes the extreme value of the selected magnitude on the whole structure. The evaluation is done for one single critical combination, resulting in a continuous deformation.

 

 

Remark:
The 3D results are currently available on 1D members and in SCIA Engineer 14.1 they will be available for 2D members as well.
