Residential Wall Standard Eases Engineers’ Role

Prescriptive Design of Exterior Concrete Walls for One- and Two-Family Dwellings is Portland Cement Association’s first standard based on an American

Prescriptive Design of Exterior Concrete Walls for One- and Two-Family Dwellings is Portland Cement Association’s first standard based on an American National Standards Institute (ANSI)-accredited process. Also known as PCA 100-07, it applies to construction of detached one- and two-family dwellings and townhouses, facilitating the use of cast-in-place concrete wall systems incorporating removable or stay-in-place formwork, such as insulating concrete forms (ICFs). In most cases, it eliminates the need for builders to hire a project engineer, potentially saving thousands of dollars.

The standard was approved by PCA’s National Standards Development Committee using the ANSI-accredited voluntary consensus process. Notes PCA Director of Code and Standards Steve Szoke, Through a cooperative agreement between PCA and the American Iron and Steel Institute, we expanded the scope to include prescriptive details for connections between concrete walls and floor and roof systems of cold-formed steel framing.

PCA 100-07 provides prescriptive designs for the construction of cast-in-place concrete footings, foundation walls, and above-grade concrete exterior walls, both loadbearing and nonloadbearing. Designs are based on the requirements of ASCE 7-05 – Minimum Design Loads for Buildings and Other Structures, ACI 318-05 – Building Code Requirements for Structural Concrete, and tests results.
