Strip footing reinforcement (75)

Strip footing reinforcement (75) creates reinforcement for a concrete strip footing.

Bars created

  • Longitudinal bars for the top and bottom surfaces and sides of the footing

  • Stirrups

Use for

Situation

More information

Straight strip footings that have rectangular cross sections

Main bars entirely inside the footing, no side bars, stirrup laps at stirrup corners.

Main bars protruding from the footing, two bars on both sides, stirrup laps in the middle of the top surface.

Do not use for

Footings that have:

  • Irregular cross sections

  • Skew or cut corners

Before you start

  • Create the concrete strip footing.

  • Calculate the required area of reinforcement.

Selection order

  1. Select the concrete strip footing.

Picture tab

Use the Picture tab to define the concrete cover thickness and stirrup offset.

Cover thickness

Description

1

Cover thickness (strip ends)

2

Stirrup offset

3

Cover thickness (top and bottom)

Main bars tab

Use the Main bars tab to define the properties of top, bottom, left and right bars.

Bond length of main bars

Bond lengths define how far main bars extend into adjacent structures at the ends of strip footings. Use the Bond length 1 boxes for the first end of the footing (with the yellow handle), and the Bond length 2 boxes for the second end of the footing (with the magenta handle).

You can define bond lengths separately for:

  • Top bars

  • Bottom bars

  • Bars on the left side of the footing

  • Bars on the right side of the footing

Stirrups tab

Use the Stirrups tab to define stirrup properties and spacing type.

Bend type

Select the location of the stirrup laps in the strip footing.

Option

At mid

At corner

End shape of double stirrup bars

If you selected double stirrup bars, you can select the end shapes for bars from the list.

Option

Examples

135-degree

Default

90-degree

Overlapped

If you select overlapped, you can enter the overlap length.

Attributes tab

Use the Attributes tab to define the numbering properties of bars and stirrups.

Option

Description

Prefix

Prefix for the part position number.

Start number

Start number for the part position number.

Name

Tekla Structures uses the name in drawings and reports.

Class

Use Class to group reinforcement.

For example, you can display reinforcement of different classes in different colors.
