Hole reinforcement for slabs and walls (84)

Hole reinforcement for slabs and walls (84)

Creates a holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

in a concrete slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

or wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

and reinforcement around the hole.

Bars created

  • Straight bars along hole edges

  • Diagonal bars close to hole corners

  • U-shaped edge bars

More information

Rectangular or round holes in concrete slabs and walls


Straight and edge bars only, no diagonal bars.

Diagonal and edge bars only, no straight bars.

Hole rotated from the direction of the slab.

One diagonal bar at each corner.

Different number of bars on each side of the hole in the wall. No diagonal bars.

Before you start

  • Create the concrete slab or wall.

  • Calculate the required area of reinforcement.

Defining properties

Use the following tabs in the Hole reinforcement for slabs and walls (84) dialog box to define the properties of the objects that this component creates:

Shape of the hole (rectangular or round):

Hole dimensions, bar dimensions and location, concrete cover thickness

Rotation angle of the hole:


Horizontal and vertical bars

Which bars are closest to the surface of the concrete (vertical or horizontal), number, grade, size, numbering properties, name, and class of each bar group along the sides of the hole

The slab or wall direction defines the direction of the hole and which bars are to the left and right of, and above and below the hole.

Edge bars

Spacing, grade, size, numbering properties, name, and class of bar group on each side

Diagonal bars

Number, grade, size, numbering properties, name, and class of bar group at each corner of the hole

Picking order

  1. Center of the hole

  2. Concrete slab or wall
