Hello all, well it really is a long time since I last posted anything on the site :oops: Derek has put the cat in amongst the pigeons again though. Durbar plate for those who know it, is a fundamental flooring plate used in all sorts of locations and yes even down under. In a previous life I worked for British Steel Corporation ( really was it all that time ago ? ) and they had a useful table , sadly not about which colour was used in the boiler-room, but of some interest anyway. For those who do not lilke algebra do not go to this link. It makes Einsteins theory of relativity seem relatively simple :D without any further ado here it is on the successor companys' web site http://www.corusconstruction.com/en/design_and_innovation/flooring/durbar_plate/durbar_design/
oh and another one

cheers for now

Hi PD's & thanks Jim for this :hammer RIVITING stuff
"The plate must be secured to prevent uplift, which would otherwise occur at the plate corners"
w = a7 py t2 / k B2 [ 1 + a8(1-k) + a9(1-k)2]
dmax = a10 k wimp B4 [1+a11(1-k) + a12(1-k)2] / E t3
I did this calculation :computer today in OZ & think I understand the need to secure the plate in each corner as my ABBUCUS result suggests that the 3ft x 3ft square plate X 6.25 mm thick is actually 87.9 Kg of negative weight.... :twisted: yes the reason you must secure the :evil: corners is to ensure it dosn't float away :angel :hehe
:oops ......maybe I used (1+k) instead of (1-k) :sorry :beer
