Reinforcement Length

Reinforcement Length

(OP)
I am doing quantities for a structure.  I was wondering what is the maximum length of reinforcement before splicing bars together.  I thought the maximum length was 60'-0".  Any help would be helpfully.  Thanks!

RE: Reinforcement Length

willijamie,
Maximum length for bars larger than #5 60'. #4 bars are to flexible at 60' and normally are 40' long. Depending on the state and manufacturer #5 bars can be 40 or 60 feet long.

RE: Reinforcement Length

Check with the owner/DOT as well.  In California, we always used 60ft - for all bar sizes.  In the Northeast, some of the DOTs specify a 30 ft max. length (unless you have a 40 ft (or so) bridge deck.  Then they'll go full-width to eliminate the splice).

RE: Reinforcement Length

Check with the owner/DOT.  MDOT limits bar lengths to 50' except for special circumstances (#3 bars are limited to 40').

RE: Reinforcement Length

Also, epoxy coated bars are more limited due to potential failure of the coating while handling and transporting.  So the #5 at 60' is usually limited to 20' less.
