STRUCTURAL DESIGN codes governing the avoidance of disproportionate structural collapse in the UK are set to receive a major overhaul, the Standing Committee on Structural Safety (SCOSS) said this week.
A government consultation on Part 3 of the Building Regulations was launched in August and is due to finish in November. Review of Part A, section 3 'Disproportionate collapse in the event of an accident' is at the heart of discussions.
However, the collapse of the World Trade Center towers last week meant the scope of the review was now likely to take on greater depth, said SCOSS secretary John Menzies.
'The current proposal is to bring all structures - not just those over five storeys - within the compass of the current Part A, section 3.'
said Menzies. 'In the light of last week's events, my view is that the profession should review what we are doing. Have our proposals gone far enough?'
Menzies highlighted that SCOSS had been 'beating the drum' for the last decade over the need to address progressive and disproportionate collapse properly.
