Hole reinforcement for slabs and walls (84)

Hole reinforcement for slabs and walls (84) creates a hole in a concrete slab or wall and reinforcement around the hole.

Bars created

Straight bars along hole edges
Diagonal bars close to hole corners
U-shaped edge bars

Use for


Situation	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.

Selection order

Select the center of the hole.
Select the concrete slab or wall.

Picture tab

Use the Picture tab to define creation of the hole, hole and bar dimensions, and concrete cover thickness.

Hole

Select to create a hole and reinforce it or to create reinforcements to an existing hole from the Create list.

Select the shape of the hole:


Option	Description
	Rectangular
	Round

Select the pivot point for hole offsets:


Option	Description
	Hole center
	Hole corner

Enter the rotation angle of the hole:

Concrete cover

Enter the cover thicknesses for horizontal and vertical edge bars.


Horizontal	Vertical

Generation start point

You can specify which point of the slab is taken as the origin where the creation plane starts. This means that the created reinforcement is aligned to the slab edge starting from that point.

Horizontal and vertical bars tab

Use the Horizontal and vertical bars tab to define which bars are closest to the surface of the concrete, and the properties of bar groups 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.


Option	Description
Grade	Strength of the steel used in the reinforcing bars.
Size	Diameter of the reinforcing bar.
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.
Name	Define the name for the reinforcing bars. 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.

Additional bars tab

Use the Additional bars tab to create additional bars and define their properties.

Enter the length of additional bars from the opening corner.

Enter the additional bars offsets from horizontal and vertical bars.

Edge bars tab

Use the Edge bars tab to define the properties of bar groups on each side.

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.

Diagonal bars tab

Use the Diagonal bars tab to define the properties of bar groups at each corner 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.
