Hard-coded bending type identifiers in reinforcement shape recognition

Hard-coded bending type identifiers in reinforcement shape recognition

Tekla Structures recognizes different 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.

bending shapes and assigns bending type identifiers to them.

The bending type identifiers in the table below are internal, hard-coded types of Tekla Structures. The leg dimensions ( D1 , D2 , and so on) and bending angles ( A1 , A2 , and so on) of reinforcing bars are Tekla Structures internal dimensions and angles. You can map the Tekla Structures internal bending types, for example, to country- or project-specific bending types, and the Tekla Structures internal dimensions and angles to specific template attributes. You can do this in the rebar_schedule_config.inp file.

Reinforcing bar bending dimensions are calculated so that the leg dimensions ( D1 , D2 , and so on) follow the outer edge, or the edge extension, of the reinforcing bar. The total length is calculated according to the center line of the reinforcing bar.

If Tekla Structures does not recognize the shape of a reinforcing bar, it assigns the UNKNOWN bending type to it.

The magenta points in the images in the table below represent the points you pick in the model when you create reinforcing bars.

Note:

If you want to customize the hard-coded bending shapes or define new bending shapes, use Rebar shape manager.

D1 = Radius from center of circle to the center line of reinforcing bar.

13

Can also be modeled using hooks at both ends (i.e. model D1 and D5 using 90 degree hooks).

14

Requires 90 degree hooks at both ends.

14_2
