Reciprocal frames enable to assemble the large span with short and small components supported mutually. However, the design and construction of three-dimensional structure tend to be more complex. In this article, we show a method to design deployable reciprocal frames from flat to curved surface by applying a method to create the elastic geodesic grid. To measure the reproducibility of the shape, we compare laser 3D scan models with real models. In addition, the models are simulated the behaviors by numerical analyses. Lastly, we reveal the challenges of designing by constructing a full-scale temporary structure using this method.

Organic adhesives used for exterior wall tiling are considered to deteriorate when used outdoors because they are organic materials. Therefore, in this study, we devised the basic performance of the organic adhesive method and a heat and cool cycling test that accelerates the deterioration of the organic adhesive, and verified its long-term durability. Considering the various conditions under which organic adhesives are used, the tests were carried out by combining bases, base treatments, and organic adhesives. In addition, an outdoor exposure test was also conducted to examine the relationship with the heat and cool cycling test.

This study proposed a ground motion prediction model in terms of natural period dependent spectrum intensity by employing an indirect method proposed by Kohranghi et al. (2018). Then, probabilistic seismic hazard analysis was demonstrated at Osaka city using a proposed model. A proposed model can be utilized to develop a probabilistic framework of displacement-based seismic performance assessment by combining with a response prediction method proposed by Furukawa & Mori (2020).

The authors conducted a questionnaire survey for the purpose of analyzing how severe the disasters are assumed in BCP and which measures are being taken. We have analyzed priority of risk countermeasures and content of countermeasures. In this paper, ratio of cumulative number of respondents to the questionnaire to the total number of respondents is regarded as subjective probabilities of restoration periods or frequencies of assumed disasters. In this way, we regard the recovery performance of facilities or the frequency of assumed disasters as a subjective probability that quantitatively evaluates how people think, and propose them as assumed curves.

The Former Army Clothing Depot in Hiroshima was built in 1913 for the purpose of manufacturing and storing military uniforms. In this building, the outer walls are made of brick, and the main structural elements of the internal columns, beams and slabs are made of reinforced concrete. It is also an A-bombed building located about 2.7 km from the hypocenter. This building has high academic value, and based on past surveys, a survey will be conducted with the aim of accumulating data for future preservation and renovation. This paper presents reference data for future repair and seismic reinforcement plans.

The purpose of this project is to clarify the relationship between sand dunes and the spatial configuration of settlements, with a focus on Takenohama, Toyooka City, Pref.Hyogo. Understanding the influence of the region’s unique climate on the formation of settlements is essential for developing sustainable livelihoods in multinatural areas. From the literature on dunes and old maps and drawings of the settlement, it was found that the Takenohama settlement is a combination of two spatial forms, defined by a topography consisting of dunes.
