Stability of Columns Subjected to a Random Axial Load
Using an analog computer for simulations, an empirical relationship is developed for the stability condition of a pin-ended column, which is excited by a 'physical' white noise. This relationship is then applied in two practical examples. In the first example, the column stability of a typical building subjected to earthquake loads is considered. The results of this example suggest that dynamic instability caused by earthquake excitation is not likely to be a problem in structures designed according to the current AISC specifications. In the second example, a hypothetic column for a spacecraft structure is subjected to the Saturn V random vibration design environment. In this example, it is found that under certain conditions dynamic instability may be a problem. (Author)
