Despite the fact you have chosen the ‘always curved’ or ‘only straight till axis’ option for longitudinal reinforcement, ConCrete Plus does not draw curved anchorages.
This is because ConCrete Plus calculates two anchorage lengths:
- anchorage length required for a straight anchorage
- horizontal part of the anchorage length required for a curved anchorage
As long as the first one is smaller or equal as the second one, ConCrete Plus will choose for a straight anchorage. This is because the curved anchorage implies more steel (horizontal part + corner + vertical part). Evidently you can always as a hook manually by clicking on annotation of the longitudinal reinforcement.
