Line support

Boundary conditions definition is always a tricky task when modeling the structure in FEA software. The model with only properly defined supports can capture reality. There are five types of supports in IDEA StatiCa Detail, let's find out what are they for.

Line support is the third type of support in IDEA StatiCa Detail. It acts as a group of spring supports within a defined length on the edge or area of the model.  Spring stiffness is either default (corresponding to the structure stiffness above the support) or defined by the user. There is a possibility of modeling non-linear support acting in compression only. This kind of support is perfect for any support which does not fit to assumptions of the first two supports (point distributed, bearing plate), especially line supports and spring supports of the piles acting in compression only.
