Struct4U tapered section

You can optionally enter a tapered beam. The tab "Profile end" is activated. Here you can enter the 2nd profile at the end of the bar.

Attention! The basic shape of the profile (H-, U-, L-shape, etc.) must match that of the profile at the beginning of the beam.

Force distribution

For the mechanics calculation, the beam is automatically divided into a number of beam parts with a length corresponding to the average profile height. The profile section properties such as moment of inertia are calculated in the middle of each beam part. A constant moment of inertia is calculated for each beam part. Because the beam parts are quite short, this approach proves to be sufficiently accurate.

Stress testing

For stress testing, the profile section properties are calculated per section (per x-distance). Thus, this calculation is exact.
