The maximum strength of steel frames caused by inelastic instability is discussed. The frames with various geometries and loading conditions (see Table-1 and Table-2) are analyzed by previously proposed method (see Trans. of A.I.J. Vol.110, 113, and 116) From analytical results the critical load formula is discussed and following formula is proposed, [chemical formula] where parameters K_1 and K_2 depend on frame geometry and loading condition. For portal frame with column thrust and increasing horizontal loading, K_1, K_2 -values are respectively 0.54 and 0.46. q_<cr>/q_R is ratio of failure load to rigid plastic collapse load considered the reduction of plastic moment by axial stress and p_e is elastic buckling load. The relations between q_<cr>/q_R-value and natural period of frames are also discussed in this paper and, following expressions are obtained as critical load formula for elasto-plastic steel frames subjected to column thrust and increasing horizontal loads. For portal frame ; q_<cr>/q_R=1.0-2.3T_0-13.5T_0^2 For multi-story frame ; q_<cr>/q_R=1.0-2.63T_0-17.6T_0^2 [chemical formula] T : natural period of frame with vertical load. h_0 : height of standard story of frame (in cm).

Interaction relations between axial force and biaxial bending in a plastic moment of H-sections are considered herein. Assumptions are the sectional plane remains plane after deformation and the area in a flange or a web is considered as it concentrats in its center line. An illustration of interaction relations is shown in Fig. 6.

In this paper, from the moment-curvature relations obtained in Part I, a method to analyze the relations between lateral load and central deflections in reinforced concrete members under axial load is developed. To confirm this sesult, four groups of test series with percentreinforcements of 0.50, 1.04, 1.57 and 2.22 in top and bottom were prepared. Each group consists of five series N_0, 2/3N_0, 1/3N_0, 1/6N_0 and 0 N_0 according to axial force level as indicated in Table 2. Test specimen is shown in Fig. 17 and tests were carried out by a special testing device as shown in Fig. 16. Test results of moment curvature relation and load deflection relation are plotted in Figs. 19 and Figs. 20 respectively and compared with the analytical results shown in dotted lines in it. From these figures, the flexural behaviours of reinforced concrete members subjected to axial load analyzed fairly well by the method mentioned here. From this study, it can be concluded that the rotation capacity of plastic hinges in reinforced concrete members decrese rapidly with the increse of axial load X・N_0 and of reinforcing index β_sP. This is of considerable importance for aseismic design of reinforced concrete structures.

On the distribution of roomsise in Japan classified by the number of rooms, there is the minimum ratio in dwellings of 2 or 3 rooms, and it's grade is very small especially in public rental dwellings. The 58% of all our dwellings are under 6 tatami (≒9.5m^2) per one room, and in public rental dwellings, it up to 85%, (in the case of 3-room public rental dwellings, it shows 98%). Japanese average number of rooms is 3.82 per one dwelling, this ratio is not so small in comparison with the other advanced nations, but it's standard deviation (1.9 rooms) is comparatively largest one. Such tendencies may be caused either by difference of the measurement method of each units, or by the existing large gap between the upper and the lower, or both. I hope the uniformity of the measurement for the international comparison in such study. There is no difinition of lower limit in the research of Japanese dwelling room areas.

This is the fourth report of the several series of investigations on the function of housing estate in human life. The purpose of the research is the same with the one mentioned in the first and second reports. This time, actual survey was done to the people in two groups living in 108 houses and 120 dwelling units in 5 "slab type" flats at Hirohata-Estate, housing quaters of the Fuji-Seitetsu Company, during November and December in 1963. Some of the results of the research are as follows : 1) Social contact in neighbourhood by the inhabitants is dominant as for wives and a pretty deal as for husbands also, while it develops in the office ajacent to the housing quaters. 2) Much contact in neighbourhood is rather done in the private houses or dwelling units than in public facilities such as a meeting room, assemblyhall etc. Inhabitants have visitors in their home almost every day. 3) People do their shopping in the housing estate not only for the daily provisions or necessaries but also for some of the extensive and hobby goods. This seems mainly due to the location of the estate apart from the shopping streets of the large city. 4) People spend the most of leisure time in their own private houses. In this meaning, the houses or dwelling units should also be designed for these leisure time. 5) People have, so to say, a feeling of "community" for the housing estate areas.

The Nose district, as is so called in this paper, is the part administratively consisting of Nose-cho and Higasi nose mura and lying in the northernmost of Osaka Prefecture. Farm houses in the district are of two types ; one is the tumairi-tatewari type, whose plan contains two longitudinally divided parts with rooms arranged mainly in front and the rear, and the other the hirairi-yokowari type. Our previous paper has already testified the oldest houses in the district not only to have been those of the tumairi type but also to have approached the hirairi type in their plan and construction, and finally, to have got fully prepared for an easy transition to it by shifting the direction of roof ridge. Furthermore, not to mention the influence of the hirairi type upon the tumairi, such a trasition as mentioned above was traceable to the unstability of room arrangement and construction comon to the houses of tumairi-tatewari type. Those except a few at Yosikawa at the extreme west of Higasi Nose mura, which lies east of Nose cho, have disappeard. An old resident in the village says that there stood a fair number of the tumairi houses tens of years before ; hence, the whole district turns out to have been the range of tumairi houses. On the other hand, our investigation shows that those houses of hirairi type which wear built in the latter days of the Tokugawa Shogunate and later have been found in Nose-cho where tumairi houses still remain as a group, while in Higasi Nose mura a considerable number of old hirairi houses with four rooms have been found which are judged to have been built at least not later than in the middle Edo period. Such houses with four rooms were widely distributed south of the district over the plains of Osaka and Hyogo Prefectures, and yet, in the plains of Osaka they had already had a difinite form in the early Edo period. Such being the case, from the plain of Osaka the hirairi houses are considered to have been introduced in the Nose district, and the time when they were introduced is concluded to have been about the middle of the Edo period. Thus, the tumairi houses, subdued by the stability of hirairi houses, were to disappear earlier in Higasi Nose mura than in Nose-cho.
