LESSON 3: Saving the solution


In this lesson you will define the solution parameters:

For each category of reinforcement elements used in the reinforcement solution (i.e., the rectangular frame, the three distributions) you need to define parameters.

In this example, you will create 4 categories, each category grouping the parameters the user can change.

  • Rectangular Frame – groups the rectangular frame parameters: Standard, Steel grade, Diameter, Cover A, Cover B, Cover C and Cover D.
  • Distribution - Right Side Zone – groups the Right Side parameters: Spacing and Zone length.
  • Distribution - Central Zone – groups the Central parameters: Spacing.
  • Distribution - Left Zone – groups the Left Zone parameters: Spacing and Left.
  • Sketch Parameters groups the defined distances in the reinforcement solution: d1, d2 and Left.

Before starting

First, set the beam opening distance.
  • On the Sketch Designer toolbar, click  AC Tutorial RBS - Lesson 3: Button.
  • In the "Define Distance" dialog box, on the Between points tab, set the beam opening distance between the C1 and D1 points and set the name to O for the distance.
  • AC Tutorial RBS - Lesson 3: Setting the beam opening.

  • Click OK.

Step 1: Create a reinforcement category for the Rectangular Frame.

  • On the Reinforcement solution toolbar, click  AC Tutorial RBS - Lesson 3: Button.
    The first window of the reinforcement solution creation wizard displays the solution preview.
  • AC Tutorial RBS - Lesson 3: Solution preview

  • Click Next.
    The "Characteristic conditions" dialog lists the reinforcement solution available for the selected model.
  • AC Tutorial RBS - Lesson 3: Reinforcement solution available

  • Click Next.
    In the "Parameters" dialog box define the parameters grouped by categories.
  • Click Add category.
  • In the "Input name" dialog box, set the name for the reinforcement category: Rectangular frame.
  • Click OK. The Rectangular frame reinforcement category appears in the "Dynamic reinforcement parameters" panel.
  • AC Tutorial RBS - Lesson 3: Dynamic reinforcement parameters panel

  • Click OK.

Step 2: Add parameters to categories.

Add the following parameters to the Rectangular frame category: Standard, Steel grade, Diameter, Cover A, Cover B, Cover C and Cover D.
  • In the "Parameters" dialog box, in the "Object properties" panel, select the Standard parameter from the Rectangular frame branch.
  • Click  AC Tutorial RBS - Lesson 3: Button to add the selected parameter to the Rectangular frame category in the "Dynamic" panel.
  • AC Tutorial RBS - Lesson 3: Dynamic panel

Similarly, add the Steel Grade, Diameter, Cover A, Cover B, Cover C and Cover D parameters to the Rectangular frame category.

Using the same process, create all the necessary categories:

  • Distribution – Left Side Zone: Spacing and Lleft parameters of the first distribution
  • Distribution – Central Zone: Spacing parameter for the central distribution (Distribution 3)
  • Distribution – Right Side Zone: Spacing and Zone length parameters for the right distribution (Distribution 2).
    Since the user has to set the right distribution length, define a new parameter: Zone length.
  • The Sketch parameters category with d1, d2 and Left parameters:
  • AC Tutorial RBS - Lesson 3: Sketch parameters

Step 3: Add formulas to the parameters.

In this step you will add the necessary formula for the parameters and save the solution.

In this example, the Lright length must be calculated based on the Zone Length (user defined parameter - the right distribution length) and the other parameters defined in Step 2.

In the first lesson, two specific points were defined: H1 and J1 (the first and the second point of the central distribution). The left distribution is placed from the H1 sketch point to the column side, leaving a gap. The right distribution gets a similar gap.

It is necessary to define the central distribution length so that between the central distribution and the right distribution the gap is equal to the d2 distance. The two gaps are joined into one at the right column face as shown in the image below.

Calculate the Lright parameter:

Lright = O – Lleft – Central Length

The Central Zone Nr Spaces can be calculated in two ways, as the integer part:

AC Tutorial RBS - Lesson 3: Central Zone Nr Spaces

The Central length can be calculated based on the distribution spacing.

AC Tutorial RBS - Lesson 3: Central length

AC Tutorial RBS - Lesson 3: Central length

Where O is the D1 – C1 distance.

AC Tutorial RBS - Lesson 3: D1 – C1 distance

  • In the "Parameters" dialog box, in the Object properties panel, select the Lright parameter from the Sketch parameters branch.
  • AC Tutorial RBS - Lesson 3: Parameters dialog box

  • Enter the formula given in the beginning of this step.
  • =[SKETCH.O]-[Sketch parameters.Lleft]-round(([SKETCH.O]-[Sketch parameters.Lleft]-[Distribution - Right Side ZoneRight.Zone length])/[Distribution - Central Zone.Spacing]-0.5)*[Central zone.Spacing]

    Where Round (x-0.5) calculates the integer part of x and O is the D1 – C1 distance.

    Note: The sketch parameters are listed by clicking the arrow located on the right side of the dialog box.

    For example, to add the O parameter to the formula, click the arrow and select O from the Sketch category. The parameter is displayed in the field.

  • Click Finish.
  • Save the solution as rbs_beam.
