Abstract
The major part of an investigation that began about 15 years ago consisted in testing 75 spherical model domes made of microconcrete Some were subjected to rapidly increasing uniform radial pressure until they buckled and some were subjected to a radial pressure held constant until they buckled two of the latter specimens have not yet failed ten years after the constant load was applied Nonlinear calculations reflecting the effects of the rapid loading and of the loading of long duration have been carried out and their results have been compared with the data obtained experimentally The numerical results do not support GERARD’s and KOLLAR’s creep buckling hypothesis while the set of experimental results of the longterm loading tests supports the hypothesis quite well in a statistical sense
