6- Reinforced Concrete Sections

1.0 Introduction

In this tutorial we'll explore the various options available in the Concrete Designer dialog. To begin, we'll first quickly set up the basics of the model, then specify the reinforced concrete section.

Topics Covered in this Tutorial:

  • Concrete Designer
  • Pile Properties
  • Concrete Pile

    Finished Product:

    The finished product of this tutorial can be found in the Tutorial 6 – Reinforced Concrete Sections.rspile2 data file. All tutorial files installed with RSPile can be accessed by selecting File > Recent Folders > Tutorials Folder from the RSPile main menu.

    2.0 Setting up the initial model

    2.1 Project Settings

    1. Go to Home > Project Settings project settings
    2. In the General tab ensure Units = Imperial and Program Mode Selection = Pile Analysis.
    3. In the Pile Analysis Type tab ensure Pile Analysis Type = Individual Pile Analysis and Laterally Loaded is selected.
    4. Click OK to close the dialog.

    2.2 Soils

    1. Go to Soils > Define Soil Properties soil properties icon and define the following soil properties:

    3.0 Design Reinforced Concrete Section

    3.1 Define Pile Section Properties

    1. Open the Define Pile Section Properties dialog by selecting Piles > Pile Sections define pile section properties icon. Here we'll define a circular reinforced concrete section.
    2. From the Cross Section dropdown, select Circular. Set the Diameter to 3.42 ft.
    3. From the Section Type dropdown, select Reinforced Concrete.
      Note that the Design button is now available.
    4. Set the Compressive Strength to 34,000 psf.

      Pile Section Properties dialog - Reinforced Concrete Section
    5. Click on the Design button to launch the Concrete Designer.

    3.2 Concrete Designer

    The Concrete Designer has 4 tabs, allowing users to fully define a reinforced concrete section. For more detailed information, we have the following help topics:

    By default, the concrete section is not reinforced.

    1. In the Reinforcement tab, click on the Add add icon icon to add and define a reinforcement pattern:
      • Rebar Size = US Std. #9
      • Pattern type = Radial
      • Number of Bars = 14
      • Angle from X Axis = 0
      • Distance from Center (in) = 13

      We will now add a casing in the Casing tab. This tab allows the user to add a casing and to specify the necessary parameters.

    2. Check the Add Casing box and enter the below properties:
      • Casing Thickness (in) = 0.5
      • Yield Stress of Casing (psf) = 420,000
      • Elastic Modulus of Casing (psf) = 200,000,000

    3. Finally, we'll add an I-beam to the center of the pile using the I-beam tab. Check the Add I-Beam checkbox and define the I-beam as shown in the figure below:
      • Type = American Steel
      • W 12x72
      • Yield Stress (psf) = 420,000
      • Elastic Modulus (psf) = 200,000,000

    4. Click OK to close the Concrete Designer dialog and save your changes. Click OK to exit the Define Pile Section Properties dialog and save your changes.

    4.0 Defining the Pile Type and Loading

    We can now specify the pile loading.

    1. Select Piles > Single add pile to open the Add Pile dialog.
    2. Add single pile
      Add Pile - Geometry
    3. In the Geometry tab, click on the Edit Edit icon icon for Pile Type 1 and specify a Length of 50 ft.
    4. Click OK to return to the Geometry tab. Leave everything else as the default values.
    5. In the Loading tab, add only a Moment Y of 50,000 lb-ft.
    6. Add pile - loading

      Add Pile - Loading
    7. Click OK to exit the dialog and save your changes.
    8. You'll now be prompted to place the pile. Enter 0,0 in the command prompt in the bottom right of the screen and then press Enter.
    9. You have now defined a reinforced concrete pile.
