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.
Patch support is the fifth type of support in IDEA StatiCa Detail. It is a point support with a specific area through which the reaction is transferred to the model. The reaction is applied directly to reinforcement, explicitly specified (otherwise it is applied into a concrete). The utilization of such support is quite obvious – precast concrete lifting anchor system, especially steel plate welded to reinforcement, basically all kinds of lifting anchor system fastened (welded) to reinforcement or supported the anchor against it. Another use of this support is the modeling of the bearing of the ledge beam (indirect support system).
