Wash (59)

Use the Wash (59) component to model typical washes along with their typical reinforcement.

Use for

Before you start

Create slabs using the Create concrete beam command or with a slab component.

Note:

You cannot use the Wash (59) component in slabs that are created as a polygon plates, such as slabs created with Create concrete slab command.

Picking order

Select the slab objects. If the slabs are created with a component, activate the Select objects in components switch before selecting slabs.
Click middle mouse button.
Pick points counterclockwise to indicate external boundary (points 1 to 4 in the picture above).
Click middle mouse button outside the external boundary.
Pick points clockwise to indicate internal boundary (points 5 to 8 in the picture above).
Click middle mouse button somewhere along the internal boundary.

Wash tab

Use the Wash tab to define the method of wash, configuration of the elavation/thickness and size of wash, recess depth, and mesh to be created in the wash.

Specify the wash step dimensions, D1 and D2, to define the top elevation of the internal boundary relative to the surface of the precast floor units. Note that D1 and/or D2 can be zero (0.00).


Option	Description
Elevation is specified	Select the method to use to specifiy the elevation of the exterior boundary surface of the wash: Absolute elevation, EL: you can to specify the top surface elevation relative to elevation 0’-0’’. Relative thickness, H: you can specify the top surface as a uniform thickness above the underlying precast floor units. Use control points: Tekla Structures uses the polygon input points as the actual 3 dimensional nodes of the top surface of the wash. Use this option to place a wash over any sloped surface.
Elevation value, EL	Enter an appropriate value based on the choice picked in the list box above. This input box is grayed out if you have selected the Use control points option.
Topping configuration	Specify whether the wash is integral with the underlying precast unit (monolithic) or poured on site.
Concrete material	Specify the concrete strength for the wash from the material catalog.
Reinforcing mesh	Select the mesh reinforcement from the mesh catalog.

Advanced tab

Use the Advanced tab to define the alter the elevation of individual nodes.


Option	Description
Exterior control point indexes	Specify one control point or multiple control point indexes simultaneously.
Thickness	Specify the actual elevation/thickness (thickness at individual control points).
Interior control point indexes	Specify one control point or multiple control point indexes simultaneously.
D1	Change the thickness at each interior control point.
D2	Change the recess depth at individual control point.

Attributes tab

Use the Attributes tab to define the required mesh and concrete properties.


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.
