Wall panel (64)

Wall panel (64) creates reinforcement for different wall panels. Contains options to create strands and stirrups. Is suitable also for insulated wall panels. You can easily change the direction (horizontal or vertical) of most reinforcing bars. Automatically creates parallel or diagonal corner reinforcement around the openings and notches.

Objects created

This component contains the following reinforcement groups:

  • Strands

  • Longitudinal reinforcing bars

  • Transverse mesh

  • Transverse straight reinforcing bars

  • Transverse closed stirrups

  • Reinforcement for openings

To omit any of these reinforcement groups, set the reinforcing bar size or the mesh grade to zero.

Use for

Situation

Description

Reinforcement created with default settings for a wall panel with a door opening.

A cross section from the wall reinforcement.

Limitations

Does not create reinforcement for the ledges in the wall.

Before you start

Create the wall panel.

Selection order

  1. Select the wall panel.

Strand template tab

Use the Strand template tab to define the strand positions with grid points within the wall cross section. Strands may only be located at the positions defined in this template, but the template allows for a mixture of regular and irregular points.

Strand at opening creation

Select to create strands at the opening or not.

Strand direction

Changes the direction of strands in the wall.

Grid Spacing along X

Use to define grid spacing values for the x axis. Separate values with commas or spaces. The first value is the distance from the left edge of the spandrel. Each successive value is the distance to the next grid point.

Tip:

Use multiplier to define a repeating series of values. For example, 8*2 indicates eight holes with a two unit spacing.

Grid Spacing along Y

Use to define grid spacing values for the y axis. Separate values with commas or spaces. The first value is the distance from the bottom edge of the spandrel. Each successive value is the distance to the next grid point.

Strand pattern tab

Use the Strand pattern tab to create strands at the grid positions defined by a strand template.

Same as left

Use to simplify strand input.

  • Select Yes to use the row and debond information of the left end for the strands at the right end of the spandrel.

  • Select No to specify alternate row and debond information at each end of a strand.

Strand pattern definitions

Use the strand template positions in the strand grid to specify the row and column for each end of the strand. Strands may have different grid row positions at each end, but a strand may not cross grid columns.

Select a Length type to define the end constraints of the reinforcing bar group within the member length. Depending on your choice, enter additional information is in the L, C, or D fields.

Option

Description

Full length

Reinforcing bar extends the full length of the wall panel – excluding the minimum end clear distance at each end. The L, C, and D fields are disabled.

Centered

Specify a fixed length L for the bar which the component centers in the length of the wall panel. The C and D fields are disabled.

Known L, C

Specify a fixed length L for the bar and a distance C from the start of the wall panel. The D field is disabled.

Known L, D

Specify a fixed length, L for the bar and a distance D from the end of the wall panel. The C field is disabled.

Mesh tab

Use the Mesh tab to specify mesh for reinforcement in the wall panel.

Mesh properties

Select the mesh from the catalog and Tekla Structures fills the other fields automatically.

Layer properties

You can specify one to three different layers of mesh. Each mesh can be different or identical.

Option

Description

Side cover

Concrete cover thickness.

Ht to layer

Specify height to the center line of each layer – h1, h2, h3. If you leave this field blank, no mesh is created.

Left end distance

Specify clearance distance for the left end. This is the dimension d1 in the pictureimage above.

Right end distance

Specify clearance distance for the right end. This is the dimension d2 in the image above.

Continuous

Specify whether the mesh is continuous over the wall panel length, or is used only at the end(s) of the wall. The options are:

  • Select Yes: Mesh extends the full length of the member

  • Select No: Mesh can be defined at each end using the L1 and L2 fields.

If any openings are present, the component will trim the mesh around the opening using the end distance (d1) dimension as a clearance.

Left end length

If the mesh is used only at the ends of the wall, enter the length for the left end. (L1)

Right end length

If the mesh is used only at the ends of the wall, enter the length for the right end. (L2)

Cross bar location

Defines whether the crossing bars are located above or below the longitudinal bars.

Transverse Straight bars tab

Use the Transverse straight bars tab to specify transverse straight reinforcing bars with varying spacing in the wall panel.

Properties of wall transverse straight bars

  • Specify the side clear cover.

  • Specify the end distance to the center line of the first reinforcing bar from each end.

  • Specify the quantity and spacing of reinforcing bars in zones next to each end.

  • If you need another group of reinforcing bars at each end, specify the quantity and spacing of reinforcing bars in the second group. If the second group is not required, enter 0 in the quantity field.

  • If reinforcing bars are required to extend the length of the wall panel, specify the maximum spacing allowed between end groups – Spacing in the third group. If Spacing is left blank, there is no additional reinforcing bar between the end groups.

Note:

At openings, this component adds reinforcing bars at each side of the opening using the side cover dimension as distance from the opening to the center line of the reinforcing bar. These reinforcing bars are in addition to the typical reinforcing bar.

Option

Transverse stirrups tab

Use the Transverse stirrups tab to define the distribution of the stirrups along the wall panel. You can define up to five zones for the distribution. If the selected wall panel is an insulated wall, Tekla Structures details the stirrups in the structural (thicker) wythe only. If both wythes are the same thickness, Tekla Structures details the stirrups in the same way in both wythes.
