Prestressed Reinforced Concrete Solution - Prestressing Materials
Prestressing Materials
The material library properties for prestressing steel are divided in 5 different groups:
- General properties: common for all the materials (number, reference,
type ...).
- Stress-strain analysis diagram.
- Stress-strain design diagram properties.
- Prestressing steel specific properties.
- Prestressing steel code properties.
User-defined library: It’s possible to define/modify any material
property from the library and create a user-defined prestressing steel library
that is stored inside the program’s library for later use.
Any kind of prestressing steel
3D Tendon Geometry editor for beams and solid element models
Each tendon is defined independently in both plan
and elevation views.
The 3D alignment of the tendons inside the structure is performed automatically
by the program.
Allows intuitive graphical definition of the tendon layout
in both plan and elevation views.
Tab-view system for tendon editor, that
allows to switch between side and elevation views.
Positioning of 3D tendons
based on reference points and curvatures. Automatic 3D alignment generation
of the defined tendons. Second order Bezier curves are used by the program
to create the tendon layout.
Possibility of selecting and viewing a cross
section with the corresponding location of tendons displayed. Many graphic
options are available.
Data table view with a graph and a list representation
of all prestressing losses throughout the structure that can be customized
by selecting or unselecting different options.
The tendons can be placed
in both Beams and Solid element models.
Calculation of instantaneous and
long-term losses for both beam and solid elements.
Any Tendon Editor view
may be exported in WMF vectorial format to be used with other programs.
Prestressing losses
Short-term prestressing losses are automatically considered for the effects
of anchorage slip of tendons, friction between tendon and sheath and elastic
concrete shortening.
Long-term prestressing losses are automatically considered
for the effects of Creep, Shrinkage and Steel Relaxation of tendons.
Variation
of prestressing in tendons considered for the effects of prestressing order.
All the geometrical data and calculated losses for each tendon can be
graphically shown on a graph and on a table, which can be completely configured.
Precast concrete losses calculation (New).
Transference of prestressing actions (Prestressed forces and moments)
The resultant prestressing actions, after all the losses are accounted
for, are automatically transferred to the model by means of an equivalent system
of forces at each node of the element crossed by the tendon.
Automatic calculation
of isostatic and hiperestatic prestressing forces.
Prestressing actions are
calculated for both beam and solid elements.
Checking of Prestressed Concrete Structures
Checking and design according to codes taking into account the prestressing
tendons.
Serviceability Limit State: Cracking checking according to codes,
taking into account the prestressed effects.
Ultimate Limit State Checking
(Axial+Bending checking): Checking taking into account the prestressing effects
for both isostatic and hyperstatic structures.
Concrete Interaction Diagram
taking into account the prestressed actions.
Shear and Torsion Check and
Design of prestressed concrete cross sections according to Eurocode 2. (New)
Shear and Torsion Check and Design of prestressed concrete cross sections
according to ACI code. (New)
Shear and Torsion Check and Design of prestressed
concrete cross sections according to EHE code. (New)
Other structures
This module features can also be applied to other kind of prestressed
structure projects, even on a model made up of beam elements.
