Camber extensions

The user can specify whether camber should be foreseen on the beams for the main bending direction. If yes, he/she can input the camber values per span, or let the software determine the camber within specific production limitations.

When camber is designed, the user can describe the production practice of the shop where the beams will be cambered:

  • the minimal and maximal values of meaningful camber;
  • precision: how should the designed camber be rounded;
  • aside from the production limitations, camber can be limited to a percentage of the dead load deflection to prevent over-cambering the beams.

The cambered shape is parabolic, by default, for spans supported on two sides and linear for cantilever spans. The user may select to use a triangular (bilinear) camber shape for beams supported on two sides: useful for beams where camber is achieved by welding two parts together.

In addition, when cambering spans that are split into multiple beams, SCIA Engineer is able to address the critical load combinations for each of the beams in the span and determine a camber value that fulfils all deformation requirements.
