## Function

- Calculate the equivalent cross-sectional area considering the Tendon and Reinforcement.
- Has improved the ease of inputting reinforcement for PSC, Composite Steel-I, and Composite Steel-Box sections.
- We support the capability to input arbitrary stress points for various cross-sections.

## Call

From the main menu, select **[Properties] tab > [Section Properties] group > [Section Manager] >**** [Reinforcements]**

## Input

Longitudinal reinforcement can be input in various ways (point/line/arc/circle/polyline types can be input in the grid).

The way of inputting Reinforced Shear became convenient.

Section Manager dialog box(Reinforcement Mode)

### Target Section & Element

Display the Target Section about which the reinforcement data is to be produced in the Tree.

### Longitudinal Stiffener

**Both end parts (i, j) have the same reinforcement**: Check the box if the reinforcement is identical for both i and j ends of an element. If this option is unchecked, different reinforcement data can be entered under each I and J tab.

### Coordinate

**Centroid**: When Centroid is selected, the Centroid becomes ( 0, 0 ).

**Left-Bottom**: When Left-Bottom is selected, the Left-Bottom becomes ( 0, 0 ).

**Guide Line**: If the value is entered, guidelines are generated using the entered spacing relative to the inner and outer lines of the section.

### Guide Line

The Guide Line feature for cover thickness allows you to input a cover thickness value, and it generates guidelines at a distance equal to the input value from the outer boundary of the section.

### Type

There are five ways of entering Reinforcements (Point, Line, Arc, Circle, Polyline).

**Point Type**

**Center Point (y,z)**: Location of the reinforcement

**Dia** : Diameter of the rebar

**Line Type**

**Input Method A**

**Ref. Y, Y**: A reference point in element local y-direction. Distance can be entered from the centroid or left most position.

**Ref. Z, Z**: A reference point in element local z-direction. Distance can be entered from the top or bottom fiber of a section.

**Num**: Number of rebars

**Dia **:Diameter of the rebar

**Input Method B**

**Starting Point(y,z)** : Starting point of the reinforcements

**End Point (y,z)**: End point of the reinforcements

**Num**: Number of rebars

**Spacing**: Spacing of rebars

**Edge Bar**: Specify whether to place the rebar at the edge or not

**Dia** : Diameter of the rebar

**Arc Type**

**Starting Point(y,z)** : Starting point of the reinforcements

**Passage Point(y,z)**: Intermediate point of the reinforcements (1 point)

**End Point (y,z)**: End point of the reinforcements

**Num**: Number of rebars

**CTC**: Number of rebars

**Edge Bar**: Specify whether to place the rebar at the edge or not

**Dia** : Diameter of the rebar

**Circle Type**

**Center Point(y,z)** : Center point of the reinforcements

**Radius**: Center point of the reinforcements

**Num**: Number of rebars

**CTC**: Number of rebars

**Dia** : Diameter of the rebar

**Poly Line**

**Starting Point(y,z)** : Starting point of the reinforcements

**Passage Point(y,z)**: Intermediate point of the reinforcements (n points)

**End Point (y,z)**: End point of the reinforcements

**Num**: Number of rebars

**CTC**: Spacing of rebars

**Edge Bar**: Specify whether to place the rebar at the edge or not.

**Dia** : Diameter of the rebar

### Reference

Select the Reference to locate the reinforcement within a section.

**Ref.Y**: Reference in the Y axis (Left, Centroid, Right)

**Ref.Z**: Reference in the Z axis (Top, Centroid, Bottom)

**Ref.Point**: Reference point for entering CTC (Start, Center, End)

**Part**: The part option is only activated when a section is a composite type. For the Composite Steel I and Composite Steel Box section type, reinforcements can be placed only at Part 2.

**As**: Total area of reinforcements that applied into the selected section.

### Reinforce Shear

**Both end part(i, j) have the same stiffeners**: Check the box if the reinforcement is identical for both i and j ends of an element. If this option is unchecked, different reinforcement data can be entered under each I and J tab.

**Diagonal Reinforcement**: Inclined shear reinforcement

**Pitch**: Interval of the inclined shear reinforcement

**Angle**: Angle of inclination for the shear reinforcement

**Aw**: Total area of inclined shear reinforcing steel

**...** : The "Area of Reinforcement" input field is activated to enter the reinforcements.

**Steel Bar for Web**: Shear steel bar

**Pitch**: Interval of shear steel bars

**Angle**: Angle of inclination of shear steel bars

**Ap**: Total area of shear steel bars in webs

**...**: The "Area of Reinforcement" input field is activated to enter the reinforcements.

**Pe**: Effective prestress of the total shear steel bars in webs

**Shear Reduction Factor**: Reduction factor for effective prestress

**Torsional Reinforcement**: transverse torsional reinforcement

**Pitch**: Interval of transverse torsional reinforcement

**Awt**: Total area of transverse torsional reinforcing steel

**...**: The "Area of Reinforcement" input field is activated to enter the reinforcements.

**Alt**: Total area of longitudinal torsional reinforcing steel

**...**: The "Area of Reinforcement" input field is activated to enter the reinforcements.

**Enclosing Stirrup**: Input the data needed to calculate the enclosed section area used to calculate the torsional moment.

**Auto Calculation**

**Cover Thickness**: cover thickness of the enclosed stirrup

**Include Flange/Cantilever**: Check on this option when the I-type section flange and the cantilever part of a box type section is included in the Cover Thickness.

**User Input**
