Abstract
A field study of 20m-span ice dome (17m base diameter and 6.5m height) was developed in the year 2000. The test-dome showed a high structural efficiency, so in the following winter of 2001, the experimentation was taken a step further by carrying out a field study focusing on both the construction and creep test of a 30m-span ice dome (25m base diameter and 9.2m height). Based on the findings from these studies, it can be concluded that the application of a 20〜30m-span ice dome should be feasible.
