Meshreinforcement that represents a mesh of steel bars in two perpendicular directions
In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.
Bars for Rebar set and Mesh bars by area for Rebar set create reinforcement for concrete slabs or walls.

|Reinforcement for the bottom or the top surface of the concrete element, or for both.|
|Component||To create mesh bars|
|Mesh Bars for Rebar set||
The reinforcement is created automatically.
|Mesh bars by area for Rebar set||
The reinforcement is created automatically.
Use the Picture tab to define how the top and bottom bars are created.
|Create bars||Top bars with primary bars above secondary bars|
|Top bars with secondary bars above primary bars|
|The same options are available for the bottom bars as well.
The value defined in the box is the cover thickness for the top/bottom layer.
If you only want to create bars in the middle of the slab, select the No bars option either for the top or bottom bars, and then select Yes in the Place central list that appears.
|Mesh area perimeter||This option is only available for Mesh bars by area for Rebar set.
Select the outline that the mesh follows.
The meshes in the examples are created by picking the same points but with different mesh area perimeters.
||Part, for example:
||Polygon, for example:
|Polygon + part
||Part + polygon, for example:
|Same as bottom||Select whether the top bars are created using the same properties as the bottom bars.
If you select No , enter the top bar properties.
Select the diameter of a bar.
Define the strength of the steel used in the bars.
You can set the grade separately for the top primary and secondary bars, and for the bottom primary and secondary bars.
Select whether the spacing is based on the number of bars or the spacing value.
Distance between the bars.
Tekla Structures calculates the number of bars.
You can set the spacing separately for the top primary and secondary bars, and for the bottom primary and secondary bars.
|Number of bars||
Number of bars.
Tekla Structures calculates the distance between bars.
You can set the number of bars separately for the top primary and secondary bars, and for the bottom primary and secondary bars.
|Primary bars direction||
The direction of the primary bars. Use to change bar direction.
If the Auto option is selected, the primary bars are created along the two longest parallel sides of a slab. If there are no parallel sides, then the bars are created along the slab x direction instead.
Select which sides are regarded as the top and bottom sides of the slab.
If the Auto option is selected, then the bars are created on the side with the greatest area.
Use the Detailing tab to control how the bars are distributed.
Select how the distance between the bars is measured.
|Step tappering||Rebar set is created normally|
|Creates as many bars as possible with same length at the tapered edge.
The value you enter is the maximum allowed shortening of a bar.
|Bar behavior at cuts||
Select how bars next to openings are handled.
Bar end conditions tab
Use the Bar end conditions tab to control the cover thickness and bar hooks.
|Use bar end conditions around holes||Select whether the same bar end conditions are used around the openings as at part edges.|
|End conditions||Creates a straight bar without a hook at the given end of a bar.|
|Creates a 90° hook at a given end of bar.|
|Creates a 135° hook at a given end of bar.|
|Creates a 180° hook at a given end of bar.|
|Creates a hook with a free angle at the given end of a bar.|
|Bending radius||Bending radius at bar ends|
|Bending length||Bending length at bar ends|
Use the Splicing tab to control the splicing of the reinforcing bars.
Select whether the reinforcing bars are spliced or not.
Select the manufacturer of the reinforcement.
|Maximum length of bars||Maximum reinforcing bar length after which the bars are spliced.|
|Lapping length||Length of the lapping connection.|
|Splicing in same cross section||Select how many reinforcing bars can be spliced in the same location.
|Splicing symmetry||Select the symmetry that is applied when the reinforcing bars are spliced.
|Splicing offset||Offset of the splice center point from the point where the reinforcing bars originally met.|
|Minimum splitting distance||Minimum longitudinal distance between two splices in consecutive bars.|
|Bar position||Select whether the lapping bars are on top of each other or parallel to each other.|
Use the Attributes tab to control the bar group or mesh properties.
|Name||Name of the bar group or mesh.|
|Prefix||Prefix for the position number of the bar group or mesh.|
|Start number||Start number for the position number of the bar group or mesh.|
|Class||Class of the bar group or mesh.
If you create a mesh, only the class of primary bars is taken into account.
