As a rescue dome that can be used as a living space at the time of a disaster, this research aims to realize an expanded geodesic dome structure, and advances analysis model construction and numerical structure analysis. In recent years, a great earthquake such as the Great East Japan Earthquake and the Kumamoto earthquake has occurred, it is said that the Nankai Trough earthquake will occur in the near future. In such a disaster, temporary housing will run short. This is because it takes a lot of time and labor to install the temporary housing. Therefore, in the case of disaster relief activities requiring prompt action, it is easy to assemble to anyone, and a structural building that can withstand aftershocks becomes necessary. Therefore, we propose an expanded type geodesic dome structure. The purpose of this research finds problems and improvements of the dome. As a result, the dome could only make one unit, but it was able to improve stability.
