Abstract
In the previous report subtitled "Organization of Domes and Theoretical Analysis under Uniform Vertical Load", we made sure of possibility of composing the domes with connecting of the uniform isosceles triangles and we found that the axial force and displacement were not so large as we could not design the frames economically by theoretical analysis. In this report, we report the experimental results of model octagon dome by loading test under uniform vertical load, by which we found we could put confidence in the theoretical results and these domes were safe under uniform vertical load. We could make certain of possibility of these domes by the previous theoretical analysis and this experimental analysis.
