Reinforcement improvements

Reinforcement improvements

Tekla Structures 2017i comes with many improvements in reinforcement.

Rebar sets in curved structures

Rebar sets can now have three guidelines. This makes it easier to create rebar sets for curved concrete structures.

In curved beams, polybeams, strip footings, and 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.

panels, Tekla Structures automatically creates three guidelines for longitudinal rebar sets. For crossing rebar sets, Tekla Structures creates a polyline guidelinedefinition of the distribution and direction of the reinforcing bars in rebar sets

The spacing of the reinforcing bars is measured along the rebar set guideline. The rebar set guideline can be a line, or a polyline that may have corner chamfers.

with three points, and the midpoint has theArc point chamfer.

For more information, see Examples: Rebar sets in curved structures.

Secondary guidelines of rebar sets improved

To easily create secondary guidelines for a selected rebar set, you can now use the new button on the contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

The user can customize the contextual toolbar.

The term mini toolbar is used in Tekla Structures until version 21.1.


To define if a secondary guidelinerebar set guideline that can be used in addition to the rebar set primary guideline to modify the geometry, direction, and spacing of reinforcing bars in a rebar set

Rebar set secondary guidelines can be used to create curved reinforcing bars or to define a different spacing at the start and end of the rebar set reinforcing bars, for example.

, select the secondary guideline and use thebutton on the contextual toolbar. Alternatively, you can set Inherit from primary to Yes or No in the secondary guideline properties in the property pane. By default, the secondary guidelines inherit the spacing properties from the primary guideline.

Rebar shape placing tool

Tekla Structures 2017i introduces a new tool for creating rebar sets. Rebar shape placing tool for rebar sets is similar to Reinforcing Bar Shape Catalog for reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure

The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.

groups, with new useful functionality and improved usability.

Rebar shape placing tool is available on the Concrete tab, under Rebar set.

With Rebar shape placing tool you can reinforce both parts and pour objects using predefined bar shapes. The rebar sets you create may extend across single or multiple objects.

You can easily select cross sections or object faces that you want to reinforce, and then, using a preview and direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

, place rebar sets in the model.

Improvements in Rebar shape catalog

In Tekla Structures 2017i, the bar shape preview in the Reinforcing Bar Shape Catalog dialog box has been updated.

For example:

can reinforcing bars have the return at each end parallel to the panel? (in 17 and previous versions returns stick out at right angles)
