| Abstract | We report the progress of our research on buildings and their surroundings for disaster prevention in Chuo-3, Ota City, which is an area in Tokyo, Japan with Densely Built-up Wooden House Areas. In a previous paper, we reported the results of an exhaustive survey of 383 buildings and roads in the northwest area of Chuo-3. As a continuation, in this paper, we present findings from an exhaustive survey of 426 buildings and microtremor measurements on the ground in a more widespread area. As a result, we found evidence of early Showa period billboard architecture. We subsequently measured the dimensions of the billboard architecture and surveyed the materials of the walls, roofs, windows, etc. Furthermore, we constructed a standard billboard architectural model and conducted eigenvalue analysis to evaluate their respective vibrational properties, such as the natural frequency and vibrational mode. Lastly, sensitivity analyses were conducted on the floor rigidity or materials of the walls. |
