Hard-coded bending type identifiers in reinforcement shape recognition
Tekla Structures recognizes different reinforcing bar 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.
If you want to customize the hard-coded bending shapes or define new bending shapes, use Rebar shape manager.
