In designing the lagging, it looks like ACI 318 Section 9.3.3.1 and Table 9.6.3.1 result in no stirrups required as Vu in not greater than(phi)Vc and the depth is less than 10 inches. I do plan on putting #3 at 8" o.c. beginning 2" from the ends to the middle. I was stumped as to why the examples I was looking at had an s much greater than the d. ie. H(depth)=8", d=4", s=8" #4 but my understanding now is this is nominal steel, although not sure why the use of #4 vs. #3. Does this seem reasonable?
I plan on wood top down behind the piles and then precast bottom up. This is our first use of concrete lagging, to date we've used timber for all permanent soldier pile walls.
