The program verifies and checks iteratively prestressed beams or reinforced concrete beams, 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 ELEMENTS IN VARIOUS CONFIGURATIONS (drawn close, centrals with infill elements, on the edge with infill elements)

CALCULATION OF CROSS-SECTION WITH CUTS OF WINGS HOLE AND DIFFERENT CAST IN PLACE HEIGHT  (for double tees and floor beams)

Possibility to add LATERAL BOSS EXTRUDES FOR THE DIFFERENT PHASES(for double tees)

Simplified choice of the element to be calculated

Check of the load on wing (for wingspan)

Automatic calculation of the torsional component of the loads, with the possibility to edit the eccentricity (for asymmetric beams - shed)
Calculation of central beams and edge beams (with or without wind force) (for asymmetric beams - shed)
Automatic shear center (for asymmetric beams - shed)
Automatic geometrical characteristics
Asymmetrical Prestress verification with automatic calculation of torsion (for asymmetric beams - shed)
Automatic verification of support with and without the Gerber support, considering torsion too (for asymmetric beams - shed)

Calculation of the half beam (for double slope beams)
Superior peak flat (for double slope beams)
Asymmetric beams (for double slope 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.

Functionalities available with PREF DRAWING module:

WORKSHOP DRAWING WITH QUANTITIES

Parametric  stirrups and rebars
Numerous types of stirrups and rebars
Numerous types of lifting hooks
Embeds
Export to dxf and pdf

 

The element is verified from the Eiseko's calculation programs, then PREF DRAWING  automatically generate the working shop drawing with the detailed Bill of Materials, according to the calculations: stirrups and rebars are the minimum possible.

PREF DRAWING  automatically generate the working shop drawing with the detailed Bill of Materials, according to the calculations. The drawing is made by two sheets, the second one can be directly be send to smith and includes all the details for the production of the reinforcements. The drawing complies ISO standards.

Drawing can be directly printed or exported to DXF or PDF and always include the detailed Bill of Materials.

The drawing COMPLIES ISO STANDARDS

The program includes a lot of parametric stirrups types. Also rebars are parametric and customizable.

There are about a ten of customisable lifting hooks.

Any stirrup, rebar or hook you use that is not present in our database will be added.

Embeds can also be added, which will be drawn on the sheet and shown in a special table.

It is possible to set the colors of the lines / texts, the thicknesses, the tolerances in the settings

The program set the reinforcement as the minimum needed to verify the checks. User can edit the reinforcement as desired.

 

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

Automatic calculation of all the geometrical characteristics

Working shop drawing with the detailed Bill of Materials according to calculations and complying ISO standards. Numerous types of parametric stirrups and rebars

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

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
