This free guidance provides identification and remediation solutions for Reinforced Autoclaved Aerated Concrete (RAAC) planks. RAAC has been used in building structures in the UK and Europe since the late 1950’s, most commonly as precast roof panels in flat roof construction, but in the 1990s structural deficiencies became apparent.
This paper aims to provide some guidance on the unusual characteristics of concrete-encased steel-framed buildings.
The article explores ways to justify reuse of existing structures through a thorough understanding of the original building structure, and engineer’s intent.
