Encased duct analysis
Encased duct analysis
(OP)
I need help analyzing the strength of this 26” square encasement(see attachment). I need to know strength of concrete in flexure and shear. 3000 psi concrete and it is going to run horizontally with a max span of 22 ft between piles.

#3 ties at 12 seems light. Use 3" cover minimum all around; check the aggregate size of the mix to ensure you leave enough clear distance between the bars and the pipe.
