Parameters for component reinforcement

Tool(s): Component Reinforcement + Modify Component Reinforcement

You can define parameters for component reinforcement using four tabs: Flight, Foot, Head and Advanced. Any changes you make to the parameters are reflected in the stair reinforcement. In other words, the entire reinforcement of the stair is created again immediately if you have already selected a precast stair. The Type of reinforcement placed is defined automatically for stairs without landings at the bottom and/or top and cannot be changed.

Flight tab

You can use this tab to define the reinforcement for the flight of stairs.

Bars in flight of stairs

BL of bar

When you select this check box, the program creates bottom reinforcing bars in the flight of stairs using the following parameters.

Diameter

The list box presents the diameters defined in the bar cross-section catalog.

Same concrete cover

When you select this check box, the program applies the same concrete cover to all the edges. In this case, you only need to enter the concrete cover once.

If this check box is not selected, you can define different concrete covers for the individual edges. You can see the position of each concrete cover in the graphics. There you can also click a concrete cover and define the value.

Length of segment 1

This parameter is only available when open stirrups are used to reinforce the top of the stair. This defines the anchorage length of the reinforcement applied to the flight of stairs in the upper layer at the top of the stair.

Spacing

Select a value in the list box or enter any value to define the spacing.

Mesh in flight, anchorage at bottom/top

Mesh

When you select this check box, the program creates bottom/top mesh reinforcement in the flight of stairs using the following parameters.

Select mesh

The list box presents all mesh types steel grades defined in the cross-section catalog.

Same concrete cover

When you select this check box, the program applies the same concrete cover to all the edges. In this case, you only need to enter the concrete cover once.

Length of segment 1

This parameter is only available when open stirrups are used to reinforce the bottom/top of the stair. This defines the anchorage length of the reinforcement applied to the flight of stairs in the upper layer at the top of the stair or in the lower layer at the bottom of the stair.

Lateral concrete cover

You can specify the concrete covers for the two sides of the stair. You can see the position of each concrete cover in the graphics. There you can also click a concrete cover and define the value.

Foot + Head tabs

You can use this tab to define the reinforcement for the bottom and top of the stair.

Type of reinforcement placed

You can specify whether open stirrups or loops are used to reinforce the bottom and top of the stair. The setting you make here defines the bending shape for the reinforcement of the flight of stairs and the parameters provided.

Bar at support at bottom/top

These parameters are not available when open stirrups are used to reinforce the bottom/top of the stair without a corbel.

Open stirrup 1/2 or loop stirrup

Depending on the check box you select, the program creates the corresponding bar reinforcement using the following parameters.

Diameter

The list box presents the diameters defined in the bar cross-section catalog.

Same concrete cover

When you select this check box, the program applies the same concrete cover to all the edges. In this case, you only need to enter the concrete cover once.

Length of segment ...

This defines the segment, anchorage or overlap length of the open stirrup or loop. You can see the position of each segment in the graphics. There you can also click a segment and define the value.

Spacing

Select a value in the list box or enter any value to define the spacing.

Cross bar at support at bottom/top

The list box presents the diameters defined in the bar cross-section catalog. You can see the position of each bar in the graphics. There you can also click a bar and define the value.

Bar, landing a bottom/top - flight

Bar "TL of landing, BL of flight"/"TL of flight, BL of landing" or Open stirrup, loop

Depending on the check box you select, the program creates the corresponding bar reinforcement using the following parameters.

Diameter

The list box presents the diameters defined in the bar cross-section catalog.

Same concrete cover or concrete cover

When you select this check box, the program applies the same concrete cover to all the edges. In this case, you only need to enter the concrete cover once. The same applies for the Open stirrup, loop type.

Length of segment 1/2 or Anchorage length in landing/Length of final segment/Length of segment in the middle

This defines the segment, anchorage or overlap length of the bar where the stair bends or of the open stirrup. You can see the position of each segment in the graphics. There you can also click a segment and define the value.

Spacing

Select a value in the list box or enter any value to define the spacing.
When the bar type is set to Open stirrup, loop, the spacing is based on the middle of the horizontal bars. The clear spacing of the open stirrups is thus obtained from the difference between the spacing and the value entered for Length of segment in the middle .

Cross bar, landing a bottom/top - flight

These parameters are only available when open stirrups are used to reinforce the bottom/top of the stair. The list box presents the diameters defined in the bar cross-section catalog. You can see the position of each bar in the graphics. There you can also click a bar and define the value.

Advanced tab

Invoicing

Meter/Length factor

You can specify whether the bars of the stair reinforcement are cut to length or created per meter. When you select this check box, you need to specify the Length factor by which the bar lengths are multiplied to take lap joints into account.

Note: At the moment this parameter has no effect on the component reinforcement. The program always create bars that are cut to length, regardless of this setting.

Production

You can make element-specific settings that are relevant to production.
