min rebar in machine fnd
fellers,
i am designing a 3'-3" thick machine foundation pad. the pad is large enough where the 92,000 pound milling machine comes to about 1200 psf overall. the loading is not great but am i to use rebar reinforcing at a minimum amount based just on the 3'-3" thickness? i am going to show rebar in the top also to help with crack control or is there a better way for this?
thanks!
fella <g>:
i just posted a query on skin reinforcing recently; you might want to review the responses.
