Minimum Bearing of Ground Beam
Minimum Bearing of Ground Beam
(OP)
Hi, can anyone suggest me any minimum bearing reference from any code for prestressed ground beams like the one attached?
Thanks a million.[img ]

I am not confident you will find such a reference.
My limited experience with a similar precast product from AU was several decades ago for residential applications where bearing of these beams were 110mm to match the thickness of 1 skin of brick/masonry wall, sometimes 230mm if there was an engaged brick pier, or an isolated brick pier. But again, these were residential loadings, not commercial.
From a code prescribed minimum, I think you will be out of luck - and given that these products don't have shear reinforcement AND the prestressing strands have zero development at the ends, I assume that any the precast manufacturers (or one of their collective trade organisations, maybe) have done testing-to-failure of their product/s to arrive at an 'acceptable minimum'.
Did you ever 'fix' the longitudinal cracking to your other 'ground beams' of this: thread507-423137: Prestressed Ground Beams ?
