Rebar placement in icf foundation walls
« on: February 07, 2010, 08:51:25 PM »
I am a mechanical engineer and I have little knowledge about foundation design. My question has to do with rebar placement in icf walls (or most other concrete residential walls for that matter.) Why is it that when I look up vertical rebar placement for below grade applications, the charts will say #5 rebar at 24" o.c. for example. The charts/details show the vertical rebar in the center of the concrete wall. It seems to me that placing the rebar here is least beneficial since it is at the neutrual axis of the wall. Shouldn't the rebar be placed towards the tension (inside) of the basement wall? I am just curious if anyone knows why they show the rebar in the centerline of the wall. At that location it would just prevent cracks from spreading, not necessarily taking the tensile load of the wall (since it is at the n.a.)

Thanks

Larry
