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 SkyCiv Foundation bietet a: Einzelheiten, SkyCiv Foundation bietet a, Eingang und Ergebnisse.

ich. Einzelheiten

Once the user has chosen a design code, dem Benutzer wird das angezeigt “Einzelheiten” SkyCiv Foundation bietet a. The units will be chosen automatically based on the design code chosen

Zahl 1. Project tab details

The user can fill the information for the project details, sowie

• Ein Projektname
• Eine Projekt-ID
• Ihr Firmenname
• Der Designer
• Der Kunde
• Projektnotizen (open ended notes)

Diese Informationen werden in den generierten Designbericht eingefügt.

II. SkyCiv Foundation bietet a

Zahl 2. Foundation tab details

Summary of inputs on the “Stiftung” Tab:

• Foundation ID – assign numerical identification to each foundation.
• Art – In der Menüleiste auf der linken Seite “Isolated Foundation” from the drop-down menu.
• Unterstützt – boundary conditions for the foundation (Siehe Abbildung 3)
  Pin (FFFFRR) – resists vertical and horizontal forces, Drehung, but bending moments about local Y and Z axis
  3D Pin (FFFRRR) – resists vertical and horizontal forces ONLY
  Fest (FFFFFF) – resists vertical and horizontal forces, as well as moments
• SW – self-weight factor
• Status – resultant of foundation design
  Bestehen – the input parameters in the foundation is adequate.
  Scheitern – the input parameters in the foundation is not adequate.
• Bearbeiten – click this to start inputting data and edit your foundation
• Löschen – delete the foundation

Zahl 3. Type of Supports

III. Eingang

Zahl 4. Selecting the Isolierter Fuß on the drop-down menu.

Users can establish the type of foundation as shown in Figure 4, In der Menüleiste auf der linken Seite “Isolierter Fuß” to bring up this view

Zahl 5. Foundation Tab

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

• Left Tab
  Separates the different input categories such as: Footing, Spalte, Soil, Materialien, Ladungen, Reinforcement and Design Parameters.
• Screen Tab
  User can select different diagram configuration such as Geometry, Analytical or both simultaneously (Die meisten Projekte erfordern geotechnische Berichte, die die Eigenschaften des Bodens und die Gesamtmerkmale des Standorts beschreiben 6). This is where dimensions, Einheiten, 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. Zahl 6 shows these three views.

Zahl 6. (links) Geometry Diagram (Center) Analytical Diagram (richtig) Both Geometry and Analytical Diagram

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

Footing Configuration

Zahl 7. Right Tab of selected Footing Configuration at the left tab.

Siehe Abbildung 8 for the nomenclature of the foundation dimensions:

Zahl 8. Foundation with designation

Column Configuration

Zahl 9. Right Tab of selected Column Configuration at the left tab.

Hinweis: Zum λ_s Modifier – Per ACI 318-14 Sektion 22.6.5.3 – The value of λ_s ist 40 für Innensäulen, 30 für Randspalten und 20 für Eckspalten.

Siehe Abbildung 10 for the nomenclature of the foundation dimensions:

Zahl 10. Foundation with designation

Soil Configuration

Zahl 11. Right Tab of selected Soil Configuration at the left tab.

Hinweis: Soil values are usually found in the Geo-technical Report.

Materialien

Zahl 12. Right Tab of selected Material button at the left tab.

Ladungen

Wann “Ladungen” are selected, a pop-up window will appear:

Zahl 13. Loads input window after clicking Ladungen

Verstärkung

To navigate between the reinforcement in the X and Z direction, and the column reinforcement, toggle between them using the buttons on the upper right of the Right Tab with Verstärkung selected.

Zahl 15. Right Tab of selected Verstärkung button at the left tab.

Zahl 14 details the direction nomenclature for the X and Z reinforcement

Zahl 14. Details of Reinforcement.

Rebar Code Reference:

• ASTM615 – American Society for Testing and Materials 615 : Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement
• N. – Australian Rebar Class N
• PNS49 – Philippines National Standard 49 : Steelbars for concrete reinforcement – Specification.

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

Zahl 16. Right Tab of selected Design Parameters button at the left tab.

IV. Ergebnisse

After hitting the Design prüfen Taste, your design will be directed to the “Results 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.

Zahl 17. Ergebnisse Output page

Summary of column representations:

• DIM
  Ratio of user’s input dimensions over required design dimensions.
• Umkippen
  Ratio of overturning moment experienced over allowable overturning moment.
• Gleiten
  Ratio of sliding force experienced over sliding resistance.
• Bodendruck
  Ratio of soil pressure from experienced loads over allowable soil pressure.
• Einweg
  Ratio of ONE-way shear demand over capacity.
• Zweiwege
  Ratio of TWO-way shear demand over capacity.
• Biegung
  Ratio of flexural demand over flexural capacity.
• Wie_x
  Reinforcement area along x-axis.
• Wie_mit
  Reinforcement area along z-axis.
• Status
  Indicates that the foundation design is Die Hälfte der Wandhöhe von der Unterseite der Basis für den Fall des oder FAIL
• Bericht
  Click to see detailed calculation of the design foundation
