SCI have completed a technical assessment of CANAM open web joists, to support their introduction into the UK. Open web joists are a common form of construction in North America, for long span floors and roofs. In North America, there is a Steel Joist Institute (SJI) specifically for this type of construction. Joists are typically fabricated from back-to-back angles as chords and small channel members as internals.
CANAM joists are already CE Marked and so can be placed on the European market, but it was important to ensure that the design process was fully compliant with the Eurocodes and reflected the provisions of the UK National Annex.
SCI has reviewed extensive documentation covering the entire design process from the determination of the variable actions to the individual member verification. SCI is pleased to record that the design process undertaken by CANAM is entirely appropriate. The design process conforms to the Eurocode and the UK National Annex, with additional guidance taken from SJI documents. The design of CANAM joists is therefore recognised as SCI Assessed and noted on the website http://www.sci-assessed.com/
