Calculation Program for the design and check of prestressed pretensed beams with any symmetric section geometry and with VARIABLE heigh

Calculation according to Eurocode 2 UNI EN 1992-1-1 version 2005 and Italian NTC 17-01-2018.

The program verifies and checks iteratively prestressed beams of sections that are symmetrical respect to the vertical axis. The beams can have up to two taperings. The sections can be hollow.

Beams are simply supported and they can have Overhangs at the ends. User can add CAST IN PLACE, to support loads, even with complex shape. The program will homogenize the cast in place to the beam, taking into account the different strengths of the concrete.

Partendo dall'appoggio sinistro è verificata la zona precompressa della trave in una serie di sezioni fino all’appoggio destro, di queste evidenzia la sezione più sollecitata a flessione.

This program can calculate DOUBLE SLOPE BEAMS, even with inferior slab, to calculate BOOMERANG beams, instead, see this program here.

FEATURES OF THE MODULE

  • Aggiornati alle nuove normative NTC del 17/01/2018
  • Travi di forma qualsiasi purchè simmetriche
  • Facilissimo da usare e velocissimo
  • Risultati completi, evidenziati e facilmente controllabili
  • Assistenza tecnica compresa
  • Travi PRE-TESE a trefoli scorrevoli aderenti

The program verifies and checks iteratively prestressed beams of sections that are symmetrical respect to the vertical axis, according to Eurocode 2 UNI EN 1992-1-1 : 2005 and Italian NTC2018.

Constantly updated to the newest Regulations

The verification is made in a serie of sections with constant step along the whole beam lenght + the first prestressed section + the most stressed section for bending + the last prestressed section.

The program will also verify the transitional phases: the draft, lifting, lifting / transport after a storage period

Calculation of the half beam


Superior peak flat option

smusso


Asymmetric beams

The losses of tension are calculated in the centre of gravity of the strands contained in the lower 2/3 of the beam. The calculation at limit states is executed in an exact manner based on diagrams of breakage of the strands supplied by the manufacturer of the strands.

In each section the programs checks main traction and compression sigmas on the centre of gravity and shows the minimum distance where the stirrups should be placed.  Superior and inferior reinforcement is always calculated, to absorb the tractions as requested from Regulations.

There is the possibility to calculate any section chosen from the user, with the control of main tau and sigma of traction on the whole height of the section.

Shear Verification in the not-prestressed section on support, following the method “variable strut inclination method”

Display of Constraint reactions Rare and Ultimate left and right (also shown in the calculation report).

USE DIAGRAMS research of the span-capacities diagram, given a certain reinforcement

Verification of overhang support
Verification in partial prestress

SEISMIC VERIFICATION

Verification of GERBER SUPPORT

FIRE VERIFICATION

SNOW-WIND LOADS for each Italian location for any load situation.

 

AUTOMATIC PROJECT OF THE NEEDED STRANDS The program designs the minimum needed strands FOR BREACKING VERIFICATION

AUTOMATIC PROJECT OF THE NEEDED REBARS AND STIRRUPS FOR SHEAR AND TORSION

Input of the form of the beam to simplify the beam management for the user
Parametric Autmatic sections
Handy navigation bar on left side

Automatic calculation of all the geometrical characteristics

The beam can have CAST IN PLACE and POINT LOADS. User can input piece of rebars in any point of the beams

Editing of a database of the most used roof elements for the automatic calculation of G1, so that the user doesn’t need to look through weight tables each time

Input of loads on beam using  m2 or m, user choice

Reports and tables can be exported as: DOC, RTF, PDF, HTML
Fast check or results with highlight of eventual values over the limits of the Rules, any values NOT verified are indicated in red, while the values shown in blue are the values within the limits
Graph of the minimal needed area of stirrups along the whole beam
Easy and graphic management of strands, rebars and sheaths.

Handy starting menu
Settings of defaults data can fasten the inputs of the most used configurations of beams
For users that works for more companies, it is possible to save all the default data and the parameters depending on the Company in "Criterions", so that it is easier and fast to switch from a job to another without worring about all settings. For example., it is possible to save any number of lifting ans transportation schemas.
It is possible to switch from one section to another for the verification in a few seconds and immediately see if it is satisfied or not.

SCHEME OF THE BEAM: in every moment current section, cast in place if present, rebars, pre+post tensed strands and calculation results are displayed to always keep the situation under control.

FREE ADD-INS FOR ALL PROGRAMS engineers can easily and quickly make daily calculations

  • CALCULATION OF THE REBARS AREAS (for one or more rebars, to add them and to calculate the rebar area/m)
  • TABLE OF REBAR AREAS
  • TABLE OF STRAND AREAS
  • UNIT OF MEASURE CONVERSION
  • SEISMIC PARAMETERS
  • SNOW-WIND LOADS for each Italian location for any load situation.

SO FAST IT CAN BE USED ALSO IN THE QUOTING STEP
Lots of enhancements are made according to customer request
Available Languages : Italian, English, Spanish
