Manuale d'uso

SkyCiv Foundation provides a user-friendly interface paired with powerful design to easily model isolated foundations. The Isolated Foundation user-interface is composed into 4 tabs: Dettagli, Foundations, Ingresso e risultati.

io. Dettagli

Once the user has chosen a design code, all'utente verrà presentato il file “Dettagli” tab as shown below. The units will be chosen automatically based on the design code chosen

Main Input

figura 1. Project tab details

The user can fill the information for the project details, ad esempio

  • Un nome di progetto
  • Un ID progetto
  • Il nome della tua azienda
  • Il disegnatore
  • Il cliente
  • Note di progetto (open ended notes)

Queste informazioni verranno inserite nel report di progettazione generato.

Summary of inputs on the “Fondazione” tab:

  • Foundation IDassign numerical identification to each foundation.
  • genere – dovresti sentirti pronto per affrontare progetti molto più grandi e complessi “Isolated Foundationfrom the drop-down menu.
  • supporti – boundary conditions for the foundation (Fare riferimento alla figura 3)
    Pin (FFFFRR)resists vertical and horizontal forces, torsione, but bending moments about local Y and Z axis

figura 5. Foundation Tab

Il “Ingresso” tab can be separated into three separate tabs, each serving a specific purpose:

  • Left Tab
    Separates the different input categories such as: Footing, Colonna, Soil, materiale, Carichi, Reinforcement and Design Parameters.
  • Screen Tab
    User can select different diagram configuration such as Geometry, Analytical or both simultaneously (mostrato in figura 6). This is where dimensions, units, and analysis graphics of the footing are shown.
  • Right Tab
    Changes in accordance to which input configuration is selected. This is where all of the information with be inputted.

The Screen tab (model space) in the middle can be changed to three different view by clicking the required button in the upper right of the Screen tab. figura 6 shows these three views.

Lets go over the different input categories in a little more detail.

Footing Configuration

  • N – Australian Rebar Class N
  • PNS49Philippines National Standard 49 : Steelbars for concrete reinforcementSpecification.

Design Parameters

To navigate between different Design Parameters, toggle between them using the buttons on the upper right of the Right Tab with Design Parameters selected. This section will change depending on the

IV. risultati

After hitting the Controlla il design pulsante, your design will be directed to theResults Page”. Each column, except for the last two, represents a design check completed by the Foundation module. The values are represented as unity ratios, where anything under 1.0 is a PASS, and anything over 1.0 is a FAIL. The last two columns represent the area of steel in both directions of the footing.

risultati

figura 17. risultati Output page

Summary of column representations:

  • DIM
    Ratio of user’s input dimensions over required design dimensions.
  • Ribaltamento
    Ratio of overturning moment experienced over allowable overturning moment.
  • Scorrevole
    Ratio of sliding force experienced over sliding resistance.
  • Pressione del suolo
    Ratio of soil pressure from experienced loads over allowable soil pressure.
  • Senso Unico
    Ratio of ONE-way shear demand over capacity.
  • A due vie
    Ratio of TWO-way shear demand over capacity.
  • Flessione
    Ratio of flexural demand over flexural capacity.
  • ComeX
    Reinforcement area along x-axis.
  • Comecon
    Reinforcement area along z-axis.
  • Stato
    Indicates that the foundation design is Metà dell'altezza del muro dal fondo della base per il caso del o FAIL
  • rapporto
