Durbar plate

[Red_Hamish]

Hello all, well it really is a long time since I last posted anything on the site  : 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    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   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  :  corners is to ensure it dosn't float away    

  ......maybe I used (1+k) instead of (1-k)
