Plastic behaviour and buckling of rolled structural steel members under compression and bending

This research into the properties of a 5"x5"x16lb W.F., A 36 Steel, rolled structural member was undertaken to determine the following:
i - Yield stress distribution over the cross section of the member as determined by coupon tests.
ii - Development of strain over the cross section of the member, as measured by electric strain gauges, when subjected to a) Axial loading, b) Bending Moment.
iii - The effect of previous loading of a member as a column into the region of yielding on its subsequent behaviour as a beam loaded to failure.
The following results were obtained:
i - Yield stress, particularly the upper yield stress was not uniform over the cross section.
ii - The strain distribution in the plastic range was not uniform and varied from cross section to cross section and even at closely adjacent points on the same cross section.
iii - Failure of the member, due to inadequate lateral support when loaded as a column, occurred before complete yielding was achieved. The effect of this previous loading on the subsequent behaviour of the member as a beam loaded to failure was inconclusive. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate
