a. What is the maximum pressure that the form needs to withstand if the wall is to be 114 mm thick, 10.67 m wide, and 4.27 m tall? b. What force does the ICF experience? What is the location of that force on the ICF formwork?
Insulated concrete forms (ICF’s) are becoming more and more common. Instead of using temporary forms like lumber to hold poured concrete in place until it has cured, an ICF is essentially a rigid Styrofoam container for a poured wall that is left in place permanently, providing an additional layer of insulation. See the basic layout of an ICF system in Figure 2. The form needs to provide adequate strength to contain the wet concrete (SG=2.4) until it cures. A leak or blowout at the bottom of the form would have a catastrophic effect on construction and
safety.

formwork?
