3Prestressing Material Library When selecting a material fromthe library all properties are automatically definedAny property used for prestressing loss calculation can be easily modified
4Prestressed Concrete Structures Model Creation The first step in the use of the Advanced Prestressed Concrete module is the model creation. The prestressing forces are applied later on in each one of these kinds of models:Beam element modelShell element modelSolid element model
5Prestressed concrete structures checking ANSYS®+CivilFEM® includes the Checking and Design of hyperstatic prestressed concrete structures, taking into account shear and torsion effects, conforming to the following codes:Eurocode 2ACIEHE
6Prestressed structures The calculation of prestressing losses distinguishes between Pre-tension and Post-tension structures.Therefore, for the Pre-stressed structures, CivilFEM incorporates, for example, the reinforced thermal expansion due to the heating process, in addition to the pull-in losses and elastic concrete deformation, long-term losses (creep and shrinkage, etc)
73D Tendon Geometry Editor It allows the definition and edition of the geometric and strength properties of all tendons of a structure. The geometry may be shown and edited either graphically or by coordinatesTool BarElevation ViewObject TreeInfo/Edit WindowPlan View
83D Tendon Geometry Editor It is possible to visualize the corresponding cross section and the location of the tendons along the structure.
93D Tendon Geometry Editor Graphical visualization of all prestressing losses for each tendon along the structure.
10Prestressed Concrete Module From this version v12, it is possible to define tendons with complex geometry without using the support beam
11Prestressing LossesThe prestressing loss calculation allows to obtain the instantaneous and the long-term prestressing losses for the tendons defined within the CivilFEM tendon editor.Instant losses: P1, P2, P3, PxFriction losses (P1)
13Prestressing LossesApart from the instantaneous losses, the program also calculates the following long-term losses:Concrete shrinkage (P4)Concrete creep (P5)Steel relaxation (P6)
14Prestressing LossesThe tendon properties and the calculated losses can be listed in an HTML document.ListCalculate lossesView Results
15Reads the prestressing losses from a file User Defined Prestressing LossesReads the prestressing losses from a file
162D/3D Deviation ForcesCivilFEM calculates the deviation forces produced by the prestressing tendons on any 2D or 3D solid or beam structure defined in ANSYS®.The deviation forces are defined as a specific load set automatically located on nodes and/or distributed on the elements.
17Prestressed Forces and Moments Both isostatic and hyperstatic effects corresponding to Prestressing actions are calculated
18Prestressed Forces & Moments Stresses in the support and in the middle of span.
19Checking of Prestressed Structures Serviceability Limit StateChecking of cracking according to codes taking into account the prestressing cables
20Checking of Prestressed Structures Ultimate Limit State (Axial+Bending checking)
21Other UtilitiesAlthough the prestressed utilities are mostly focused on bridge calculation, it’s also possible to make use of them in other kind of structures such as prestressed slabs, silos, etc
22Prestressed Concrete Structures Other Projects A group of loads, equivalent to the effect of the prestressing tendons will be created on the model and transferred to its nodes.This method can be applied to any kind of model or mesh (even on a model made up of beam elements)
