STANDARD FIRE VERIFICATION

FIRE RESISTANCE VERIFICATION asymmetrical prestress and shear

The additional module for the fire verification is integrated in every Eiseko's program, the user can chose to insert it in the PREF package.

It checks any section the user has previously calculated "cold", reading automatically all the needed data, geometrical data, materials, reinforcements

Rules:

  • UNI 9502 may2001
  • UNI EN 1992-1-2:2019 simplified method
  • UNI EN 1992-1-2:2019 advanced method

The program automaticaly proposes the fire exposition of the borders, of the cast in place, of the holes, then the user can modify them.

In few seconds it is possible to obtain all the results.

FEATURES OF THE MODULE

  • Automatic fire exposition of the borders and editable
  • Automatic Mesh
  • Analysis in any section
  • Automatic break and shear verification
  • Automatic verification for breack and shear

The programs calculates automatically the fire exposure of the edges, but the user can edit it. Holes are handles as cavity, inferior edges are esposed to fire, laretal ones are not exposed.

Quindi premere il pulsante arancione  SETTAGGI DEFAULT

TRAVI RTL CALCOLO TRAVI PRECOMPRESSE - impostazione del tiro massimo per il banco di tiro

Il programma RTL dà un messaggio di errore se il tiro trefoli complessivo supera i limiti imposti in “Impostazioni Tiro”.
Se si hanno a disposizione i valori del prefabbricatore si possono impostare quelli, la quota di riferimento Q.R. è spiegata, basta premere il pulsante "Vedi immagine", in alto a destra, e si ottiene questa finestra descrittiva.

TRAVI RTL CALCOLO TRAVI PRECOMPRESSE - impostazione del tiro massimo per il banco di tiro

I prefabbricatori hanno il progetto delle testate di tiro dei loro banchi di casseri.
Le testate sono delle strutture vere e proprie in calcestruzzo od acciaio a cui vanno appoggiati i martinetti durante la tesatura e a cui vanno fissati i trefoli prima di effettuare il getto delle travi nei casseri. Le testate devono reggere il tiro complessivo fino all’atto del taglio o del rilascio dei trefoli.
Il progettista delle testate le ha dimensionate in funzione di un tiro massimo dei trefoli variabile in altezza riferito ad una quota che stabilisce lui, che in genere è il piede dei contrafforti.

Si riporta uno schema indicativo.

Se non si hanno i valori del prefabbricatore si possono impostare dei valori a caso sufficientemente alti, per esempio Dist. Da Q.R. = 200 cm e Tiro = 1000 ton.

Si procede con: Elimina tutto, si impostano i valori e poi si procede con Aggiungi, Elimina Riga.

NOTE: you can call the technical support Tel. +39.045.80.31.894 and we will do the installation from remote connection

Or follow the procedure:

If you have the CD:
• Insert the CD: There are multiple folders on the CD, depending on the PREF package modules you purchased.
• All the folders and subfolders contain the installation programs, they must all be installed by launching the Setup.exe file of each folder and subfolder. The order in which the installations are carried out does not matter.
NB. DURING INSTALLATION:
o If version conflict messages appear (if you want to leave the exixting file in the system) click "No to all"
o If dll registration error messages appear click "Ignore" (or "Ok")

• Launch the Program manager - There wil be the setting of the programs
• Launch again the Program manager and enter the registration code provided by the assistance (if you do not yet have the code, press "Later").
• Launch all the purchased programs one by one, they will ask you the Database, select the mdb / mde file from the folder "C:\Users\Public\Public Documents\Eiseko Database" (the name of the database is similar to the name of the program). This operation must be done only once.

If you DO NOT have the CD:
• At the top right of this site, click LOGIN and enter the credentials you've been given.
• Download the installers of the modules included in the package
• Unzip the related downloaded zip files into separate folders. For each, launch the Setup.exe and follow the installation wizard. The order in which the installations are carried out does not matter.
NB. DURING INSTALLATION:
o If version conflict messages appear (if you want to leave the file in the system) click "No to all"
o If dll registration error messages appear click "Ignore" (or "Ok")

• Launch the Program manager - There wil be the setting of the programs
• Launch again the Program manager and enter the registration code provided by the assistance (if you do not yet have the code, press "Later").
• Launch all the purchased programs one by one, they will ask you the Database, select the mdb / mde file from the folder "C:\Users\Public\Public Documents\Eiseko Database" (the name of the database is similar to the name of the program). This operation must be done only once.


You are now ready to use the program.

There are pros and cons in both cases, the choice is very personal, but we recommend working on files.

If you work with file, you can save the file wherever you want, on the local PC or on the network (for example in the job order folder). When you create a new file of the project with the calculation program, you will have to manually select the text file of the section (created with the Geometries module) from the folder in which it was saved in. If you work on files it is good habit to make a backup of the project txt files in order not to lose the work you've done.

If you work with database you have all the beams (created with the Geometries program) and the projects (created with the calculation program) saved in the same file, whose management is automatic by the program and you don't have to worry about where you save it (you can see name and path of the file in the "Information" menu). The list could become very long. Anyway, you can do all the operations of saving multiple databases, using databases on the network, changing databases.

If you are working with a  database you need to remember to make a backup of the mde / mdb files you used. The files must be saved in a folder on the PC where the user has all access privileges (modification and saving), we recommend C:\Users\Public\Public Documents\Eiseko Database (folder created by default with the installation of the program).

In the menu at the top right select "Data Input", "CompanyData"

Enter the desired data and press "Save".

In the menu at the top right select "Data input", "User data"

Enter the desired data and press "Save".

 

Yes, it is possible. It must be done BEFORE creating all the projects belonging to a specific job order.

From the main form, press “SETTINGS” and then “SET SEISMIC PARAMETERS”.
It will open then following window, in which it is possible to associate all the seismic data relating to the location of the selected job.

Each time a new project associated with the “Example” job is created, the program will automatically propose the data of the seismic parameters (they will obviously be modifiable).
NOTE: projects that already existed before these parameters are set will continue to use the previously saved data.

 

Tutti i “dati di default”, in gruppo, possono essere memorizzati in diversi “CRITERI”: ad es, se un ingegnere lavora per più ditte, può memorizzare i dati di default validi per le diverse ditte in più criteri ciascuno con il nome della ditta. Prima di creare il nuovo progetto scegliere il Criterio della ditta per cui si realizza il progetto di calcolo. L’uso dei “Criteri” si dimostra particolarmente utile per gli schemi di sollevamento e trasporto che possono variare da una ditta all’altra.

Yes, it is possible from version 21.00.00. If you have a previous version just update the program from this site and then you will be able to select "Verify Existing" in the materials window.
