Designing Reinforced Concrete Sections from within SkyCiv Structural 3D Analysis Software

SkyCiv Software di progettazione in cemento armato allows engineers to design concrete beams and columns as per ACI 318, COME 3600, NEL 2, CSA A23 e BS 8110 (Prossimamente). Il software è disponibile come Standalone (nessuna analisi), o integrato con il nostro software di analisi; SkyCiv Beam e SkyCiv Structural 3D. In questo articolo, esploreremo l'utilizzo del design RC dall'interno di SkyCiv Structural 3D (S3D):

Modelling your Structure

The integrated RC design module allows users to model their structure and apply loads and load combinations using our Structural 3D program. This will allow the user to (un') modello, analyze and design multiple members at once (B) perform more complex and accurate analysis on the members (c) automatically import attributes such as length and section properties from the model -> RC design module.

For more information on how to model using S3D – visita il nostro getting started in S3D page.

Open the Design Module

Once you have solved the structure, you can open the design module for your particular design code. Per fare questo, visit the Design bubble in the top right corner and launch the design module of your choice:

The following information will automatically be imported into the design module:


All of your members will automatically be imported from the analysis model. This includes an auto-assign of whether your members should be classed as beams/columns as well as lengths and effective length factors. NOTA: You can edit and control any of these options at any time and your changes will be saved with your model (File – Salva).

Layout RC

Basic information such as material properties and section shapes will automatically be pulled into the module. From this part of the module you can also control the following:

  • Define Longitudinal Reinforcement: add multiple layers of reinforcement (shown as red horizontal lines), including input for:
    • Number of bars
    • ACI-Verifica-Libri-Anteprima
    • Top/Bottom distance
    • Coperchio
    • Start/End points
  • Shear Reinforcement: add multiple layers of shear reinforcement (mostrato in verde, vertical lines in the graphics)
    • Number of bars
    • ACI-Verifica-Libri-Anteprima
    • Spaziatura
    • Start/End position
  • Deflection Controls: Control limits and sustained live load percentages


[icon icon=info] Applying the same layout to multiple members

Nell'esempio sopra, you might want to apply the same reinforcement layout to all columns. You can do this by using the blue Copy to Members pulsante. This will allow you to copy the rebar characteristics across multiple members.

Carichi e combinazioni di carico

Results from the analysis are automatically imported from your analysis model, so there isn’t much else required here by the user. Users can review the loads under the Caricare tab, which will present all the check points and force diagrams (bending z, bending y, assiale, shear y and shear z) which are all used in the design calculations.

Your load combinations are also included and imported from your modelif you did not add any during the modelling phase, simply go back to Modello e add load combinations, or import load combinations from ASCE, COME, EN or CSA design standards in S3D. You can also add manual load combinations from within the RC design software.


Once you’re ready to run the design module, clic Controlla il design. The results will be displayed as a table (columns = different checks and rows = the different members). tieni premuto Ctrl e fai clic sui membri che desideriamo selezionare [mini-icon icon=info-sign”] for more information about each of the design checks. Sulla destra, the model will display a traffic-light style resultwith the governing ratio showing next to the member. In the below example it is evident that the columns are passing, but the beams are failing due to insufficient shear capacity, with a utility ratio of 3.704. This ratio is how much capacity of the member is being utilized. It means the member is 3.7 volte più capacità.

Rapporti di calcolo dettagliati

Once solved, è anche possibile rivedere i rapporti di calcolo completi che mostrano i calcoli passo passo completi eseguiti dal software. Here’s an example ACI 318 calculation report produced by SkyCiv RC design software. Questo aiuta a comprendere le ipotesi esatte, riferimenti e criteri per le verifiche progettuali. Questo può essere scaricato come PDF da archiviare per i tuoi record o trasmetterlo al cliente.
