Historically, cast-in-place concrete for residential construction has been primarily limited to below grade applications such as footings and foundation walls. Such construction was relatively labor intensive, and, therefore was not considered a viable alternative for other parts of the building. However, the recent advent of insulating concrete form (ICF) wall construction and the Prescriptive Method for Insulating Concrete Forms in Residential Construction (Prescriptive Method) has resulted in a competitive and energy efficient alternative for above grade walls in residential construction. The purpose of this test program is to investigate the structural capacity and performance of the concrete lintels typically used in ICF construction. Lintels are reinforced concrete structural elements that support loads above openings in concrete walls.
