Description

In this package post tension slabs are analyzed and designed. The slab can be constructed using either PLGEN or using Autodesk Revit.

Features and Capabilities

Boundary element analysis and design of post-tensioned slabs.
A tool to check or to verify existing software results.
Accounts for losses [friction (curvature and wobble), anchor set, elastic shortening, concrete creep, concrete shrinkage, and steel relaxation].
No internal discretization, cables can be placed freely.

Cable elongation calculations.
Long term and short-term losses calculations.
Real geometry modeling of slabs, openings, supporting and loading elements.
Easy to modify cable eccentricity.
Pre-compression check.

Multiple templates for different cable profiles (13 templates)
Minimum radius check
Easy re-analysis due to change in supports or openings places without remeshing.

Cables can be imported from CAD drawing.
Import and export DXF, text and Excel files
More than one engineer can model a problem in parallel way.

Interface with Auto Desk Revit (BIM)

The Post-Tension Package (PT-PAK) GUI:

The PTPAK tool has easy GUI to input features used to design PT- slab.

Cable material properties and jacking force together with cables’ divisions and losses data are easily input via dialog boxes.

Design strips in both directions according to area method are drawn.

The PLPost capability can be used here to draw BMD and deflection along desired strips to draw the cables profile according to them.

Importing bending moments and deflection strips in PLPAK to draw cables profiles according to them

All required load combinations can be defined.

Defining load combinations in PLPAK

Cables profile are chosen according to the bending moment distribution or deflection along linear strips.
The user has 13 cable templates to fit the desired profile.

Alternatively, the user can import the DXF file already drawn cables in ACAD program. Hence, he can edit cables properties such as minimum radius of curvature, number of strands in the cable or the total jacking force of the cable, the dead and live ends, long term losses, the cable profile.

Defining cable data in PLPAK

A plan containing the cable distribution.

Post-tensioning load cases can be solved.
Cables profiles can be saved and loaded.
