Precast Double Tee's on CMU
Precast Double Tee's on CMU
(OP)
I am designing a CMU bearing wall to support precast T's. I have never done this before. I am a little concerned about bearing the stem of the T's on the CMU. Is there anything special that should be considered? I am expecting a point load of about 31k per stem.

Consult your precast supplier regarding the connection of the double tees to the top of the CMU wall. They may recommend neoprene bearing pads, but the top of the wall must be stabilized laterally by the double tees.

I assume that you plan to have a wall with vertical reinforcing in grouted cores. I would consider using a much deeper bond beam than 8", perhaps a poured beam on top of the wall.

Please describe the detail you have where the DT flange restrains the wall.

I actually did use #5's @ 24" O/C. At another location on the building I needed #6's for wind and I had the two confused. About the restraint provided by the T slab; I plan on bringing the cmu up between the stems to the top-of-slab elevation. The slab will be cut back to the face of the cmu. The T slab will have steel embeds. I plan on using a steel plate to tie these embeds back to embeds in my cmu wall. This was recommended by the precaster's engineer.
