抄録

Recently, the various steel domes have been researched and reported, but in any case it is usual to need the various kinds of members in length to design the frames. If we could compose the steel domes with a network of the only two kinds of straight members in length, we may compose the domes with connecting of the uniform isosceles triangle plates and fames, easily and economically. We mention the idea and the basic organization of these domes with some examples. Next, we investigated the theoretical axial force and the displacement of these domes under the uniform vertical load distributing over the entire surface of the dome by Relaxation method, and we found they are not so large as we can not design the frames economically. Lastly, we induced the theoretical equation to calculate the buckling load by the elastic stability of frames with a example. By the theoretical investigation, we could make certain of possibility of the domes composed with a network of two kinds of straight members in length.
