Anchorage of longitudinal reinforcement: the basic anchorage length lb,rqd
Eurocode 2 part 1-1: Design of concrete structures 8.4.3 (2)
The basic required anchorage length in a straight bar follows from:
lb,rqd = (Φ/4)⋅(σsd/fbd) | (8.3) |
where:
- Φ
- is the bar diameter
- σsd
- is the design stress of the bar at the position from where the anchorage is measured from
- fbd
- is the design value of the ultimate bond stress.
This application calculates the basic anchorage length lb,rqd from your inputs.
