Module Prestressing makes it possible to define geometry, material and other properties of prestressed tendon. The tendon can be inserted into 1D members. It is possible to define pre-tensioned internal tendons.
The tendons are defined through strand patterns that are supposed to be symmetrical in a 1D member, thus only one (symmetrical) half of the strand along the 1D member must be defined. The input is made in three steps:
Bore hole pattern is defined, i.e. the location of holes in the "face-plate" is defined.
Sectional strand pattern is specified, i.e. which holes of the "face-plate" are "filled" with a strand/wire/bar.
Beam strand pattern is input, which means that the shape of the strands/wires/bars along the 1D member is defined (this step is subject to certain limitations that will be explained later).
Note: It is not possible to import prestressing data from EPW system.
