A four-storied prefabricated apartment building was tested by lateral static force to investigate the safty of the building to the earthquake in Japan. The building which containes 24 flats was constructed by using about 500 concrete panels, steam-cured in site, but devided into two parts, one for test building and another for reaction mass of jacks, The joints of concrete panels were "wet", that is, the all reinforcements around the panels were welded with one another, and filled with concrete. The deformations were measured by dial-gauges at the side of the jacks situated between floor, and fioor, and at the wall-floor joints of every stories. This report is concerned with the load-deformation curves at the situations above mentioned.

Bending stresses in shallow hyperbolic paraboloidshells (H.P. Shell) have been mostly evaluated by an rough approximation for example finite difference method. But a precise analysis for the fundamental differential equations of H.P. Shells [numerical formula] &lrtri;&lrtri;Φ-2chE W_<xy>=0 has not ever been shown. This paper demonstrates a precise analytical method of the boundary value problems for above equations by Fourier seriese, and this method is available for not only H.P. Shells, but also any shallow shells of quadratic algebraic surfaces and any boundary conditions.

An auditorium, having about 1000 seats, was constructed in the Kure Civic Center. A plane shape of this auditorium was designed originally as circular audience area. As is well-known, circular shape auditorium would have several acoustic defects, especially acoustic focusing or long-delayed echo. These phenomena were confirmed by the two-dimensional ray tracing analysis. To remove these defects, it was decided to adopt diffuse and absorbing walls. For the detailed design, three-dimensional model was made, and by using the optical method the paths of reflected wave from the diffuse wall and ceiling were investigated. From these investigations, the shape of the diffuse wall and the position of absorbing wall were determined so as to avoid the intense primary or secondary reflected wave which arrive at the audience area aelayed more than 50 milliseconds after the arrival of the direct wave. Acoustic investigation after the completion of this auditorium has shown that any acoustic defect due to the circular shape was not observed. Reverberation time of empty auditorium is 1.6 seconds at 500 cps., and from calculation it would be expected to become 1.1 seconds for the full audience condition. This seems to be a optimum value for such auditorium used for various purposes.

Analysis was done in three ways; First analysis mainly tries to analize the ratio of resident's satisfaction for their housing in terms of six social conditions. i) In terms of Housing ownership; [ownership pattern of houses] [ratio of satisfied accupants] a) owner of the house 66.3% b) tenants of company housing 56.7% c) tenants of rental house 51.7% Thus, "the owner of the house" (a) could be seen as having stronger satisfaction for their homes than temporary tenants. Furthee mention should be made that among "the owner of the house" (a), those who actually built the home themselves are found to have even greater ratio of satisfaction (71.1%). On the contrary, 'a single-room tenants of privately-sun tenement houses' or 'those in relocation housing (in slum area)' show lower ratio, 30.9% or 42.8% respectively. ii) In terms of Duration of settlement; The longer the occupants settle at the place, the stronger satisfaction the residents shows. [Duration of settlement] [Ratio of satisfied occupants] Those settled since 1955 52.4% Those settled before Taisho ara 71.0% iii) In terms of the Age of the head households; The older the head of household is, the stronger satisfaction is expressed. [the age household-head] [Ratio of satisfied occupants] under 30 years of age 43.7% over 70 years of age 72.8% iv) In terms of Occupancy density; Smallar density is associated with better living condition, the smaller the density is, the stronger satisfaction is expressed. [occupancy density] [ratio of satisfied occupants] less than 4.5m^2 per household member 42.3% more than 18m^2 per household member 74.3% v) In terms of Occupational group; Those who run minor business (professional, commercial, manufacturing, service etc.) show higher ratio of satisfaction as compared to worker class. And among worker class, blue collar class show lower ratio of satisfaction than that of white collar class. vi) In terms of Local background; Those born at the place or have come from adjacent region show stronger satisfaction compared to those who have come from remoter region. Especially, the resident coming from stronger region (Kanto, Kansai) show lower ratio (49.0%・41.9%) of satisfaction. The second analysis tries to test x^2-distribution of the item of resident's preference and six items of their objective status. Then, we gained results as follows; i) the relation of the item of 'Preference' and the item of 'Housing ownership' shows correlation in the reliability of more than 99.5%. ii) the relation of the item of 'Preference' and the item of 'Duration of settlement' shows correlation in the reliability of more than 99.5%. iii) the relation of the item of 'Preference' and the item of 'the Age of the head of households' shows correlation in the reliability of more than 99.5%. iv) the relation of the item of 'Preference' and the item of 'Occupancy density' shows correlation in the reliability of more than 99.5%. v) the relation of the item of 'Preference' and the item of 'Occupational group' shows correlation in the reliability of more than 99.5%. vi) the relation of the item of 'Preference' and the item of 'Local background' shows correlation in the reliability of more than 97.5%, this relation shows lower-correlation than before five relations. We have thought that those results are better comparatively. At the end, we tried to test used to Tschuprow's contingency coefficient ([numerical formula]). Then we found out that 'Housing ownership' was the strongest factor in all factor acting to 'Preference'. Their order of importance of factors acting to 'Preference' shows as follows; Housing ownership>Duration of settlement>Age of the head of households>Occupancy density>Occupational group>Local background.

In former report the farm house which produces a few kinds of merchandise in recent Iwashiro and Sinano had been discussed. In this report the sericultural hauses in which they manufacture only silk in Kozuke are discussed under same subtitle. In the historical study of recent farm house, I think the farming work-space had been rerously affected the main house in the commercial farming, and it had been still more affected silk-reeling industory in it.

Hakodate Jobiso is a building group in four brick one-story houses which was built by the KAITAKUSHI (Hokkaido Colonization Board) at Toyokawacho, Hakodate, Hokkaido in 1874 and '75. "Jobiso" means a storehouse of rice provided for emergencies. The construction of the above building group was designed in 1872 and the one among four houses elected in 1874 and the others in the next year. This building group was damaged by a spreading fire in 1907, but the two houses were restored remaining as those were nearly and those are used actually by Yasuda warehouse K.K., This building group is well-known as the one of the works constructed at the oldest age for the brick structures existing in Japan. In the view point that this was built upon the design of Eishichi Ikeda, an architect resided in Hakodate this is a valuable work which shows how much the Japanese early in Meiji era understand a brick structure and its constructive method. The present papers investigate records on this Jobiso at the time of that erection, restoration works after the fire in 1907 and details of the structure.
