In the previous paper, we have discussed the importance of plastic buckling tests of steel plates. We, therefore, carried out some experiments and their results are open to be applicable to design rules in Plastic Design. The experimental work consists of two parts; One is compression tests on cruciform cross sections and the another, on plates placed in parallel. The former is the equivalent case of flange plates of wide flange sections under compression forces or bending moments, but the latter is the equivalent of web plates of wide flange shapes under uniform compression, flanges of box sections. These tests present us a large number of useful results for Plastic Design. In real steel structures, plastic hinges are formed one by one as the loads increase until a collapse mechanism is attained. This process requires, in general, the strain-hardening of the elements in the regions of the preceding plastic hinges. Furthermore, the elements of important members, such as highly compressed or alternatively loaded, are required to be prevented from local buckling. Then, according to test results, we propose the sufficient width to thickness ratios such that it is possible to satisfy the above-mentioned requirements. (case 1) The recommended with to thickness ratio, when required such that buckling will not occur prior to the onset of strain-hardening; b/h≤16 d/t≤16 where b is flange width of wide flange section h is flange thickness of wide flange section d is depth of wide flange section under uniform compression t is web thickness (case 2) The recommended width to thickness ratio, when required such that instability will not occur before average longitudinal strain increases up to the strain at the onset of strain-hardening; b/h≤20 d/t≤21

In the previous papers, Part I and II, there were analyzed on the transverse moment-curvature and load-deflection relationships of reinforced concrete members subjected to constant axial load and compared with test results in the elasto-plastic range. Here, in this paper, the moment-curvature relationships and axially accumulated strains of reinforced concrete members subjected to transverse cyclic bending moment under constant axial load are presented. They are shown in Figs. 6 : (a-1) under the variation of several constant curvature amplitudes and several constant axial load ratios. It is discussed the influences of reinforceing indices β_s・p=σ_y/F_c・p of 0.10, 0.20 and 0.30 constant axial load ratios of 2/3 N_0, 1/3 N_0, 1/6 N_0 and 0 N_0, and constant curvature amplitudes upon the behaviours mentioned above. The hysteresis loops, m-ψ, show perfect elastic perfect plastic process under the axial load ratios of 2/3 N_0 and 0 N_0, S-figure process with smaller and slipped process with larger curvature amplitude under the axial load ratios of 1/3 N_0, and binary step slipped perfect elastic-perfect plastic process under the axial load ratios of 1/6 N_0. Axially accumulated strains are most remarkable under the higher axial load ratios but not so remarkable under lower axial load ratios and smaller curvature amplitudes. In the foregoing analysis, to simplyfy the calculation, it is assumed that, the concrete area of a cross section of a reinforced concrete member is divided into three parts, each of which is considered to be concentrated on the positions of the reinforcing steels in top and bottom and of the centroid cross section.

This paper presents how the housing expenditure including rent in the total household expenditure will vary in accordance with the size of a household, where the method of cross-section analysis using statistical data is applied. Japan's summary is as follows : Housing expenditures, unlike other items, show a tendency to decrease as household members increase. When the households are divided into three groups by tne number of persons constituting a houshold, the rent is the highest in the smallest group, the second in the largest one and the third in the middle one. The sum of food and housing expenditure accountes for about 50 percent of the total household expenditure, which has no relation to the number of person a household. The main data used in this paper are given in "Annual Report of the Family Income and Expenditure Survey in 1964" and "1964 National Survey of Family Income and Expenditure".

On October in 1965, Japan Housing Corporation made the periodical survey for the residents in JHC housing estates. This report is the short summary of that census. Main emphasis is placed upon the analysis of social stratification of residential families from the time series point of view. Some remarks are stated as follows. 1) Population Structure by age groups is defferent from that of national average. The age group between 25 and 35 takes nearly half of the total population, and 20% is occupied by the age group between 0 up to 4, 10% for 5 to 10 years. 2) This specific character is clearly seen among the residents living in the smaller housing types. Family types belonging to larger housing types are similar to the national average type. 3) As the time of dwelling in these housings becomes longer, this specific character is gradually changed to the nationally average family type. 4) Average family size is 3.41 person per dwelling 70% of all the families are taken by a family type having 3 to 4 person. 5) Average family size observed in 1960 was 3.26. This shows an increase of 0.15 person per family between 1960 and 1965. It is thought that this figure will become reached to the average urban family size within near future. On the contrary, national average of the family size is gradually decreasing. 6) A mono nucleus family type occupies 80-90% of total families. As the housing type become larger, the ratio of "Older family" increases. 7) As time elapses, the ratio of "Older family" increases and this tendency is more clear within the larger housing type. A housing type with more than three bedrooms is occupied uniformely by the different family type. 8) Average monthly in come per family is 70, 000 yen which is 70% higher than 42, 000 yer, the average one in 1960. But the variance of its distribution becomes larger. 9) Average monthly income per person in 4, 000 yen higher than that of average urban family. Living Standard of residents in JHC housing estates is thought to be considerably high.

This paper is made out according to architechtural articles of the diary of Sanetaka Sanjonishi (1455-1537), and aims to clarify various architectural productions of residences of the nobility of that age as well as to learn the basical structure. The Summary is as follows : (1) Constructive process of residence was divided into main work and fitting work. The terms of payment to the workmen for main work was contract wages system and for fittings daily wages system. These two ways originates in the process of planning; the main work was advanced according to 'sashizu' (a simple ground plan) and the fitting work under the order's indication in detail. (2) Workmen and orders were bound by family-like relationship. This kind of access relationship is humanic and rather recent than the former dominate-subordinate relationship. (3) The organization of workmen consisted basically of family unit. Some of them had the official social position as the Shogunate workmen (Government workmen), and at the same time boud private relationship of this kind of family-like relationship with specially fixed person. (4) The wage of workmen was 110 (one-hundred-ten) mon, and this was the standard amount of that days in Kyoto. (5) Timbers were mainly bought from timber-dealers, but some part of them were supplied by the accommodation among the nobilities by a habitual mutual aid.
