Sirs,

Good Morning!

Regarding development lengths, is it okay to ignore ldh for hooked bars but still hook it and let it equal to Ld for straight bars?

For more details please see attachment

Thank You in advance

dik,

Sorry, I am away on holidays and no longer have access to a copy. The local engineering library should ahve a copy!

If you search on Bing for BS8110 + 3.12.8.25.2, it comes up!
 
@dik,

IMO I don't think the supplemental reinforcement can be said to reduce the ldh for a "standard hook" since ldh is a defined constant. But if you are using some modified configuration that includes supplemental reinforcement then I certainly agree than a "standard hook" should not always be necessary in order to obtain a reduced "lead in" as it was called.

We do this sort of thing all the time in anchor bolt design when Appendix D is not suitable for anchorage in small piers. The codes/standards should not prevent an engineer from using alternate rational methods such as strut and tie, etc.
