Ties between Piers and Grade Beam

Ties between Piers and Grade Beam

Ties between Piers and Grade Beam

(OP)
What is the best way to tie piers to grade beams.
Is it better to run the rebars from the pier long enough then bend them to run parallel with the rebar in the grade beam and use wire ties to join them together rather than use bent hooks between the pier and the grade beam?

 

RE: Ties between Piers and Grade Beam

Yes, but not field bending unless you are dealing with #5 or less Grade 40 bars.

RE: Ties between Piers and Grade Beam

It depends on the depth of the grade beam, and also on how much continuity you need in your case.  But it is more typical practice to use straight bars in the pier, with bent bars in the grade beam lapping with the pier bars.

RE: Ties between Piers and Grade Beam

Two options
1 - straight bars with a tall pier cap to grade beam transition
2 - hook pier bars towards center of pier and thread grade beam bars through

I've done both but option 1 is cleaner.  The contractor has to be ready to box out the pier excavation in order to keep soil out of the excavation
