The Concrete Foundations Association has released a new design standard for residential foundation walls. This design standard is intended to serve as a guide to assist in the interpretation of applicable design requirements for the design of the traditional one and two family dwelling units.
Current structural design provisions for residential concrete construction are presented in ACI 332 or referenced in tables only from the IRC. However, the ACI 332 provisions largely refer back to ACI 318 provisions. There are numerous difficulties with this approach.
One is that this leaves the designer in the position of interpreting, which ACI 318 provisions are applicable and which ones are not. Another is that ACI 318 provisions are intended for use in traditional reinforced concrete construction in buildings and structures and therefore have many more materials and structural considerations.
It is widely held that because of these complications that this hinders the design of concrete in one and two family dwellings. It is also widely believed that the lack of an appropriate design provisions hinders the use of concrete in non-traditional applications such as above grade walls and floor slabs.
