IBC/IRC Foundation wall tables
IBC/IRC Foundation wall tables
(OP)
I have a question regarding the difference between the foundation tables in the IRC/IBC. I am looking at IRC table R404.1.1(1) and R404.1.1(3). Specifically, we have an issue with an existing 12" CMU foundation wall that is 8' in height with 7' backfill.
Table R404.1.1(1) specifies that a hollow 12" CMU wall is adequate for this condition, assuming "GW, GP, SW and SP" soils.
Table R404.1.1(3) specifies that #4 bars at 64" o.c. are required for "GW, GP, SW, and SP" soils.
I'm not understand why these are different. Either you need reinforcement or you don't. Can someone help shed some light on this as to why the two tables have different requirement's for the same wall with same high and backfill?
Thanks
