Relation of Deformations
Tips & Tricks
RF-/STEEL EC3 performs not only cross‑section and stability analysis, but it also allows serviceability limit state designs. For this, it is possible to relate the deformation to the undeformed initial system or to shifted members ends.
The “Shifted members ends / set of members ends” option is preset in most cases to consider the deformation of the entire structure for the design. However, the figure shows a beam with the reference length manually adjusted to the column length between supports. In this case, the deformation must be related to the undeformed system in order to receive the correct result of deflection in the serviceability limit state design.
