Abstract : A test program is described which was designed to emphasize the influence of plasticity on cr ep buckling and therefore to accentuate the difference between the simple theory of creep collapse and the rigorous Hoff-Fraeijs de Veubeke theory of creep buckling of imperfect columns. The results show that the differences to be expected are smaller than the experimental scatter and so are not conclusive. A compari on of the results calculated by Gerard's method and those obtained from the more rigorous theories indicates that the former method is less realistic, although in the present tests it is nearly always conservative. This conclusion is not a general one s has been shown elsewhere by one of the present authors. (Author)
