In this paper, response characteristics of three types of rectangular block in three kinds of non-shear flow or flow without velocity gradient-one is smooth flow and others are turbulent flows-are presented. Furthermore the predominant strouhal numbers, S_p, by measuring the unsteady velocity fluctuations in the wake in smooth flow are also shown. Main results are as follows. 1) The effect of the vortex-shedding on the response was found to be large. 2) Great differences were found in the response characteristics between at lower reduced velocity and in vicinity of the critical reduced velocity. i) At lower reduced velocities the response intensity increased monotonically with the velocity. An increase of turbulence intensity raised the response intensity. ii) In vicinity of the critical reduced velocity (≡1/S_p), the self-excited vibration (α≧75deg.) and the restricted vibration prior to it were observed. Here, the problem aroud the critical reduced velocity was in vestigated in cases of MODEL 8×4, 8×2; α≧70 deg..

In this paper, essential dynamic behaviors of braced structures with deteriorating characteristics subjected to random excitation are described. It is assumed that the braced structure is a single-degree-freedom system. In the former part, transient and stationary responses of the braced structure subjected to stationary white excitation are solved by Monte Carlo technique, and its essential behaviors are discussed. In the latter part, hysteretic characteristics of the braced structure are approximately formulated on the basis of numerical results, and the stationary responses of the system are solved by equivalent lineapization technique. Its results are compared with simulated results, and general behaviors on the random response of the braced structure are discussed.

In this paper, as a application of the fundamental theory considered in the previous reports (Part 1), author proposed to the method of approximate conversion to obtaine restoring force model expressed in terms of power function by formalizing skeleton curve and area surrunded by hysteresis loops. From the results applied this method of conversion to a few restoring force characteristics obtained from experiments, we found that the restoring force models were reflected in sufficiently the vibrational characterestics for hysteresis systems. The other hand, as a result applying to known restoring force characteristics to investigate the limit for applicability of restoring force model expressed in terms of power function, we found that it could be applied enough as far as nonlinearlity is not strong remarkably.

The deduction of acceleration of earthquake motions drawn from the overturning of gravestones have played an important role in determining the intensity of the great earthquake in the past. And the rocking was hitherto studied mostly only as to the motion of column caused by ground motion. In our field investigations, we often met with cases where gravestones had fallen down from the base without overturning. The authors studied not only rocking motion but also slip, rocking-slip and jump of column due to ground motion.

In the preceding reports (Part 1, 2) the concept of subsystem and rules on interface were interpreted. In this paper, the author undertakes to clarify the effects of applying the subsystem concept, and analyzes principal aspects which have to be taken into consideration to devide a total system into subsystems. Subsequently, the relation between the way in which a total system is devided and the diversity of the system is argued, and four fundamental inclinations are pointed out. Also, subdivision of a subsystem (i.e. formation of subsubsystems) is analyzed finally.

Recently, regional utilization in medical care facilities has extended into an areawide range. Therefore, to set up the medical circular region has been an urgent necessity in areawide medical planning. We have studied the composition of the medical circular region in the Miyagi Prefecture area by using the data from the national health insurance program. Miyagi prefecture is composed of 7 areawide circular regions. Through this study we obtained the results that 4 areawide circular regions-Sendai, Ishinomaki, Osaki, Kesennuma-have fixed regions with their own central city as the core; however, 3 areawide circular regions-Sennan, Kurihara, Tome-have no fixed regions but are composed of several limited circular regions. And, all these regions stated above are under the influence of Sendai City (See Fig.7).

This study constitutes the second report on a coninuing research project concerning dwelling space. The purpose of the current study is to pre-test the questionnaire which was designed according to an analytical model developed in the first report. The study examines the following three issues : 1) replicability of survey results; 2) the applicability of analytical axes; and 3) the validity of each survey item. In addition, the research explores two issues in search of hypotheses which are to be verified later in the main part of the project. They are 1) residential strata divisions and 2) dwelling needs. The questionnaire survey was conducted in October 1971 following the selection of survey items for each analytical axis. An analysis of the data resulted in the following observations relating to the aforementioned five issues. 1) As regards the replicability of survey results, a high 0.935 coefficient of reliability was obtained when Rulou's formula was applied to the scores which were separated into two groups by the split-half method. As a result, the replicability of this type of survey result seems plausible. 2) A factor analysis of the axes confirmed in general that each axis constitutes a prime factor in living ocnditions as expressed in dwelling. However, some irregularities in detail were detected. 3) The evaluation of survey items by means of a B coefficient of belonging demonstrated that most items are appropriate. The B coefficient of belong for some items concerning family relations was quite hight. 4) 14 residential strata were postulated on the basis of housing and occupants after an evaluation of data on each survey item. 5) When the structure of dwelling needs was examined on the basis of canonical correlation, the following points were indicated. a) An overall improvement program must be devised in order to solve the specific dwelling needs of the strata at lower living standards, since their needs tend to be inseparable from each other. b) The dwelling problems of the upper strata are more amenable to solution since the needs in such cases can be more independently solved compared to that of lower strata.

The Public Housing Law was enacted as a system in 1951. Since then almost 1700000 public housing units have been constructed and it continues playing an important role in the public housing policies. The first purpose of this paper is to analyze positively, what role, to what stratum and to what extent, public housing have been playing in housing conditions in Japan. The second one is to clarify the differencies of the role of public housing in different areas, namely, local characteristics. The conclusions on the occupation of household heads are as follows, 1. The occupation structure of household heads is largely inclined toward Labours. 2. The above fact is proved more sharply in the small local city in comparison with the metropolitan city. 3. The concentration toward Labourers is more in the second class public housing. 4. In the metropolitan city, the occupation structure of the first class public housing's household heads is similar to the general citizen, that is, the deviation is little. 5. However, the occupation structure in public housing's household heads had been inclined toward Office Workers at least until 1962. The conversion in the occupational structure occured after that period. 6. It is a most one of causes to have been restricting the qualification to public housing's applicants, drastically toward lower income classes.

We know that there were buildings called "Ifo", "Kari-Ifo" and "Ifori" in ancient Japan, and that some of "Ifo" buildings were used as dwelling houses. But beyond these points, in the present day, we only have rather vague architectural ideas on them, so we cannot discuss them in the history of Japanese architecture. To get more precise architectural images and characteristics of these buildings, the author throghly researched available facts through the scenes presenting those buildings in the tales and poetry of the following four areas of literature, and tried to reconstruct their images of building forms. "Kojiki". (a history of Japan, completed in 712 A.D., 3 volumes.) "Nippon-Shoki". (a history of Japan, completed in 720 A.D., 30 volumes.) "Manyoshu". (an anthology, edited in the end of the 8th century A.D.) "Fudoki". (5 provincial histories, completed in the middle of the 8th century A.D.) In this short synopsis the author will refer only to "Ifo " building which is the main theme of this paper. In conclusion the author got the following facts and ideas on this type of building. a. In the said four areas of literature, there are only five instances of "Ifo" buildings. b. Of the five instances only two of them were dwelling houses. One of them was for a very poor family, and the building had only one room with dried grass floor. Another one was allegorically used for the house of the crab of Naniwa beach, which was hiding from society. c. In both cases the dwellers of "Ifo" buildings belonged to the lowest class of the society at the time. d. The other two of "Ifo" buildings were built for the funeral rituals of nobles. Though their function in the ritual was not clear, it is very certain that they were temporary buildings. e. The last one of "Ifo" buildings showed its building form as a hillock of grass on the earth. f. Adding to these facts, many "Kari-Ifo" buildings were also temporarily built in the fields for travellers to sleep in. g. Considering these facts, the author thinks that we may take "Ifo" buildings (especially those built in the 7th and the 8th century) as rather temporary buildings with only grass roof (s). We can not take them to mean permanent buildings to live in as they have been vaguely thought of till today.

Mishioden-jinja shrine, located in Futami town of Mie prefecture, has two peculiar attached buildings. One of them, named Mishio-yakisho, is the hut where dense salt water is boiled for the offering salt of Ise-jingu, and the other, named Mishio-kumiiresho, is the shed of the pots of dense salt water. These two buildings are constructed almost only from the sloping roofs, alike as a supposed primitive type of Japanese architecture. Though the two buildings, being newly rebuilt, reveal the modern technique, they keep other various elements of the primitive architecture. For the saltworks of Ise-jingu was established before the ninth century, the origin of these buildings might be very old. The author tried to clarify the detailed history of these buildings by old documents and pictures, and on the other hand, compared them with the buildings of saltworks which were popular in Isshiki village near Futami until the Meiji era. As the result, it was presumed that the building forms of the saltworks of Ise-jingu might have been adopted from those of the folk saltworks in the neighboring beach, and the buildings of the saltworks of Ise-jingu might have been constructed with ridge-supporting-pillars, with which the buildings of the folk saltworks were constructed. This presumption is very important because the building construction with ridge-supporting-pillars was a remarkable characteristic of Japanese ancient architecture, as seen in the main shrines of Ise-jingu themselves.

The former conclusion about the present east pagoda at Yakushiji is that the core of the pagoda is a new structure erected in the Heijo capital. In this paper it is ascertained that at least the first story lean-to-roof of the extant pagoda was made from the old materials of the original pagoda in the Fujiwara capital. The main proof is that, one pillar and the roof boards of the lean-to-roof bear marks suggesting that those materials had once been used on the first story lean-to-roof unenclosed of the original Yakushiji pagoda.
