Dynamic Reinforcement Tutorial

LESSON 3: Saving the solution

**In this lesson you will define the solution parameters:**

- Step 1: Create a reinforcement category for the Rectangular Frame.
- Step 2: Add parameters to categories.
- Step 3: Add formulas to the 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**

- On the
**Sketch Designer**toolbar, click . - 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. - Click
**OK**.

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

- On the
**Reinforcement solution**toolbar, click .

The first window of the reinforcement solution creation wizard displays the solution preview. - Click
**Next**.

The "Characteristic conditions" dialog lists the reinforcement solution available for the selected model. - 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. - 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 to add the selected parameter to the
**Rectangular frame**category in the "Dynamic" panel.

**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:

#### 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.

**Lright**parameter:

**L**right = O – **L**left – Central Length

**O**is the

**D1 – C1**distance.

- In the "Parameters" dialog box, in the
**Object properties**panel, select the**Lright**parameter from the**Sketch parameters**branch. - Enter the formula given in the beginning of this step.
- Click
**Finish**. - Save the solution as
**rbs_beam**.

=[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.
