Working with timber frame contractor OFP this large two storey extension to an existing school is essentially a two storey timber frame structure with significant steel elements to frame larger openings.
Two storey education buildings have to be designed to resist progressive collapse and in timber frame that normally equates to demonstrating sufficient robustness to allow removal of one panel at a time without excessive damage.
Where collapse areas are potentially large use of “key elements” designed to resist blast loadings (normally steel) is an alternative design strategy.
