Hi.
My Local Authority needs calcs for a steel corner support column I'm proposing in my extension.
It will be approx 2.2M tall, 80x80mm square x 5mm wall. Axial loading (dead load + imposed load from snow) will be maximum of (from a rough calc) 2.4KN. I have no access to BS5950 without buying it, but Corus Steels seem to have all the tables where I can look up Axial load capacity of their tubes, and something called d/t ratio. I don't know where to work out buckling load, and I'm not quite sure what is meant by an axial load "capacity". I'm sure this need not be too complex, and I'm equally sure my column is adequate.
-Any pointers?
