Is there anyone out there who can explain the difference between limit state & working stress design so that the issue of safety factors is understood? I keep trying to explain when it crops up but I am clearly not succeeding.
Permissible stress approach is described in BS 5975 - it is the amount of bollox you listen to on these forums before you feel the need to contribute some more bollox.
Limit State is when you have heard enough and sign off..
