Mr K. G. Brunskill (M)
I am surprised that the discussion contains no mention of Dr Paul Abeles who pioneered all the work on the inverted T-beam and whose beam and slab tests of the late 1940s and early 1950s were well recorded in The Structurul Engineer at the time.
A structure is vulnerable if any damage produces consequences that are disproportionate to that damage; conversely, a structure is robust if it can withstand arbitrary damage. The purpose of this paper is to present a new theory of structural vulnerability. It is a theory of structural form and connectivity, the purpose of which is to identify the ‘weak links’ within a structure. It is not a theory of the response of a structure to loads.

Mr E C. Beale, from South Croydon, provides more background to the thinking behind his
contribution to our 16 February 1999 column:
Given that CO, emissions from humans are several times as great as the total from fossil fuels, it would seem that the minimum would be 3 times as great and that livestock emissions might be as great again. This does not take account of all the sources of CO, in the natural world, which might be as great as the previous total.
