It is suggested that ICE SHELL STRUCTURES may be an efficient method for providing an architectural solution to the problem of improving the environment in the arctic regions. This paper describes an experimental and theoretical investigation of short term static behaviour of ice domes. It contains as follows. (1) Axisymetric distributed load was applied up to failure to about fifty small scale models on a circular area concentric with the apex. (2) Tests on uniaxial strength of snow-ice material were conducted and analytical method of elastic spherical cap under same loading conditions were developed. By combination of these results, we proposed the method of predicting initial cracking loads, collapse loads and elastic deformations of test models. (3) The theoretical collapse loads moderately agreed with the experimental values.
