I have some literature from American Polysteel Forms of Albuquerque (800)9PS-FORM, that show they used equivalent rectangles for the oval shaped cores in their forms. They illustrate the cores and the equivalent rectangles. They say the equivalent rectangles are conservative approximations and they seem to be reasonable approximations. They don’t state any basis for their assumptions but they seem reasonable to me. They offered to provide sample calculations and a computer program for use in designing with their product but the project ended up with more conventional construction so I did not try to learn more about the product. If you aren’t tied to one manufacturer, you could call these people and see if they have a franchisee in your area.

Our office is in the process of a move, so most of my library is in boxes. I am attempting to do some design for a home where the architect wants to use an ICF type of wall construction. This particular manufacturer has yet to complete testing, so there aren’t design tables available from the manufacturer. Basically the vertical cells are round with a single #5 bar centered in the cell. To find the flexural capacity of the cell, can I use a square section with an equivalent area? It seems I read that in a design manual for ICF type of products but I can’t find the manual because of the move. Can anyone comment, or should I keep looking for the manual. Please don’t make me go through all those boxes.
