It is interest and important to consider what effect the bending of edge members has on the strength and stiffness of thin shear panel. But, it is very difficult to take into account the flexibility of edge members in the analysis, because of the redistribution of stresses in the web as a result of allowances for the flexibility of the edge members. In this report, an analytical results on the shear strength of thin shear panel based on the incomplete tension field theory are presented. In the analysis, the effect of the bending of edge members is considered on a simplified hypothesis that the normal load due to the tension field action distributes uniformly on the edge member, but does not consider the redistribution of stresses in the web by the flexure of the edge member. This simplified analysis described is not claimed to be a complete account of the actual behavior of thin shear panel. But the calculated results of this theory present a relatively good agreement with the results of the tests carried out by the auther on the thin shear panels with rigid edge members, and also with the test results carried out by Cooper on the welded plate girders with the flexible edge members when the aspect ratio of the panel is smaller than 1.0.

It has been theoretically proved that a system comprising a rigid body, a foundation and a number of bar groups each consisting of 4 bars coupled together at one ends via a three-dimensional pin, the other ends of two of the 4 bars being coupled to the rigid body via three-dimensional pins, and the other ends of the remaining two bars being coupled to the foundation via three-dimensional pins, has at least one degree of freedom allowing vertical translation of the rigid body, provided that in one said group a straight line connecting the pins on the rigid body and a straight line connecting the pins on the foundation are parallel to each other, and that such straight lines on the rigid body and on the foundation in all the groups lie on horizontal plane. In case that the system comprises 5 groups of bars, generally the system has one degree of freedom and no statical-indeterminacy. In case that the system comprises 6 or more (r) groups of bars, generally the system has one degree of freedom and (r-5) degree of statical-indeterminacy. In the latter case, if the system is subjected to prestress, then the potential energy due to the prestress and the gravity is a function of the position of the rigid body in the system, and the system becomes equilibrium when it takes a configuration which minimizes the potential energy. A extensible tower could be constructed connecting systems like this unit system.

The purpose of this study is to devise empirical formulae for predicting the ultimate strength of tubular joints under static loads. The joints investigated herein are simple tubular joints that include the tubular X, T, Y and Kjoints and joints having gusset plates welded on tubular members. Most of the existing ultimate strength formulae for tubular joints^<(1)〜(5), (18)〜(20)> were mainly based on those empirical relationships between the strength and the geometrical parameters of the joints which were inferred from various series of test results. The ultimate strength formulae in this report were derived by the multiple regression anlysis on the majority of test data that have been obtain since 1963. In the process of building a mathematical model for a prediction equation, it was assumed that the joint was able to be replaced by a simple and fictious structure. There are two important differences between the formulae for T, Y and K-joints proposed in this report and existing formulae. The one of the differences is that these formulae give fairly reasonable estimates of ultimate strength when D/T-ratio is greater than 21 and less than 90, whereas all existing formulae tend to overestimate the ultimate strength as D/T becomes greater than about 50 (see Fig. 7 and Fig. 13). The other difference is due to the fact that the formula takes account of such behavior of the K-joint that the strength of the joint increases as two braces intersect and then overlap with each other (see Fig. 13). It was also found that these ultimate strength formulae were able to be extended to explain the carring capacities of various tubular joints with gusset plates.

Purpose This study deals with the fire escape problem in the building but final aim of this research is to select planning variables which decide the safety of visitors from the standpoint of building design and to propose effective countermeasures to each building according to its characteristics. Object building As an object building for this research, we take a multi-story department store which stands in the city. Because it's a sort of semi-public facilities and a lot of people stay there at a time. And it's difficult to guarantee sufficient fire defense only by the restrictions of current building code, and dangerous situations can be easily anticipated when the occured a fire. Method We used computer simulation for the analysis and made a model that can trace time series state transition of both visitors' escape and the spread of smoke at the same time. In the simulation, the occupants decide the route to escape through probabilistic processing and when they choose the staircase and the way to it, they take the distance and the congestion into consideration, and those who can get out of the floor are all to proceed to the first floor. In the case of smoke flowing, the escape behavior is to be modified accordingly. The safety of visitor is judged by the smoke suffocation time in the floor and the density of congestion in the staircase, in which secondary accidents are apt to happen because of the much crowds caused by the simultaneous escape.

This study continues the previous report No.1, the following is to describe some of comparing on the condition of dwelling houses, the distribution of commercial establishments for employed persons from about the year 1935 to the year 1970. Some results are shown as follows. 1) As the previous report No.1, in Osaka in 1935, the net population density of private urban land use was remarkably high, about 514 person per hectare, on an average in Osaka city area. This value is diminished about 313 person per hectare in 1970. 2) On the other side, the average size of houses in 1941 was larged in comparison with that in 1968, for example, the number of Tatami in 1941 and 1968 are shown as Fig. 4.1 and Fig. 4.2, these figures shows to the enlarging number of small houses in 1968. 3) The enlarging of the private urban land use in Osaka from the year 1935 to the year 1970 was not profitably served for the house size enlarging, immediately. 4) Many of the employed persons for commercial establishments was lived in Osaka city area in 1935. The changing of this condition and other elements to be continued on the next report.

At the beginning the Public Housing Law was enacted, the area of floor space of public housing unit was about 33m^2 (10 Tsubo) for the first class public housing. Today, after 25 years since then, it is about 60m^2. The aim of this paper is to clarify the role of the Public Housing on the dwelling condition, and also, to grasp the differencies of the Public Housing in different regions, namely, the local characteristics. The conclusions are as follows; 1. Because of the nature of this system which has been enforced by the same rule through-out the country, we can recognize little difference among the building levels of the Public Housing in different regions. 2. The level of the floor area of Public House is lower compared to that of the average citizens housing. However there are much differencies among its situations in each cities. In metropolitan Nagoya, the relative situation of the Public Housing on the dwelling condition is higher in comparison with other cities, and in the local rural city Ono, the relative situation of that is lowest. In middle size city Toyota and Fukui, the situation of that is between Nagoya and Ono. 3. The level of the Public House in metropolitan Nagoya are approximately equal to that of the privately-rented house, but in other cities that of the Public House are lower than even that of the privately-rented house.

Throughout the Tumulus Period (4th〜7th century A. D.) in Japan, the most popular dwelling house style for the indigenous rice-cultivating people was the so called "Tateana-Zumai (Pit dwelling)", and we know of the plan of the building through archaeological excavations; of the shape of the building by three instances of bronze relief carved in the said Period. The floor of a dwelling of this type was a shallow pit dug in the ground about two feet deep, and there was a hearth in the center of the earthen floor. Covering this pit completely, there was a simple dome-like thatched roof, which had no window but had two little openings in the upper sides of the roof to exhaust smoke from the hearth. A little entrance was also cut in the lower part of the roof. (The building had no wall.) The inner-room of a "Pit dwelling" was a very closed one which could shut the exterior elements off completely. Today, we call this type of dwelling, as mentioned before, "Tateana-Zumai" because of its pit, but we don't know by what name it was called by the people of the Tumulus Period. On the other hand, we can find many buildings called "Ya", "Tono" and "Muro" in Japanese literature such as "Kojiki", "Nippon-Shoki", "Manyoshu" and "Fudoki". All of them were completed in 8th century A.D. Now the author takes up the "Muro" building in this paper. To get its architectural image and historical characteristics precisely, the author thoroughly researched available facts through the scenes presenting "Muro" buildings in the tales, legends and poetry in the said four areas of literature, and got the following points concerning "Muro" clearly. a. All of the "Muro" buildings presented in literature had very closed inner-room. b. The floor of the "Muro" building was an earthen one, and there was a fireplace in the room. c. The people who dwelt in "Muro" buildings were not the rich or noble but the ordinary native people. d. Almost all of the facts about "Muro" buildings were found in very ancient legends in the said literature. e. The origin of "Nifimuro-no-Utage (the ritual banquet for new 'Muro' buildings)" were founded in the folk custom of the rice-cultivating people in very ancient times. Comparing these points with the characteristics of the said "Pit dwelling", there are so many similar points, that the author thinks that we can take the "Muro" buildings in literature as the "Pit dwelling" in archaeological fact. This thesis consists of the following chapters. I. "Muro" buildings in 8th century literature. II. The architectural images of "Muro" buildings. III. The "Nifimuro-no-Utage". IV. The "Muro-foki (the ritual blessing for new 'Muro' buildings)". V. Conclusion.

In this paper will be added other proofs to support the former conclusion that the lean-to-roofs of the extant east pagoda at Yabushiji are made from the old materials of the original pagoda in the Fujiwara capital. The main proofs are as follows : 1. The carpenter's rule as calculated from the bays of the first story lean-to-roof of the extant east pagoda, is different from that obtained from the inner core of the building, but is the same as that discovered from the foundation stones at the site of the original east pagoda in the old Fujiwara capital. 2. It should be considered that it was when the pagoda was built that the outer pillars of the core building of the extant east pagoda were placed 1 SUN (about 1/10 foot) beyond the first planned position. We can conclude it was necessary to adjust the new core building to the old lean-to-roofs moved from the original Yakushiji. First, the outer pillars of the core building at the original Yakushiji leaned inward at the top, but it becomes obvious that the outer pillars at the Heijo Yakushiji had no inward slope from its first planning. Secondly, the carpenter's rule of the original pagoda was a little longer than that of the core building of the extant east pagoda at the Heijo Yakushiji. 3. The rafters of the first story lean-to-roof bear marks which are considered to suggest they had been used in the original pagoda in the Fujiwara capital. In reference to 1, that is, that the carpenter's rule of the core building of the extant east pagoda is different from that obtained from the foundation stones at the east pagoda site in the old Fujiwara capital, is at the same time another proof for the former conclusion that the inner core of the extant east pagoda was constructed newly in the Heijo capital. Those old materials probably came from the original east pagoda at Fujiwara, which had been dismantled and its core building was set up as the west pagoda at the new site in the Heijo capital. Consequently, it can be presumed that in this west pagoda the core building was formed of the old materials but attached to it was lean-to-roofs made of new materials. This paper also clarifies much regarding the technique of the leaning-inward of walls and pillars.

It is the object of this paper to make clear the reason of the formation of the Settan type which is the characteristic plan type among many types of the farm houses in the Edo period. Settan type is featured by having the entrance on the gable side. Judging from some of the oldest ermains in the seventeenth century, the plan of this type consisted of three chanmbers arranged in single file and dirty floor to parallel with them. Each of the chambers is called 'Zashiki' (parlor), 'Daidokoro' (living and dinning), and 'Nando' (bed room) from the front to the back. Zashiki has a wide veranda in frant of itself. Conseqently, Settan type constitutes the formalized fasade for the farm house. Settan type is distributed over three provinces, Yamashiro, Settsu, and Tanba (equal to Kyoto, Osaka, and Hyogo Prefecture at present time). What does this distribution mean? After many researches, I was aware of the correspondence of this distribution with the dominant area of the Hosokawa who was substantially the execter of the Muromachi Shogunate from the middle of the fifteenth century to the middle of the sixteenth century. In this period, the upper-most class farmers were given the political privelege and played the part of the official ruler of thier villages. On the other hand, it is thought that the residents in the houses belonging to this type in the seventeenth century were the desendants of them. It is conjectured, therefore, that Settan type was formed as the result of emphasizing the social parts in planning, that is a parlor and a wide veranda, in front. In addition to this tendency, probably, the privelege of using 'Hafu' (the triangle board on the gable side of the roof) which had been only used by the upper-class in the Middle Ages, might have been permited to them in return for their special position. As the result, the gable side of their houses might have been put in the front to exaggrate it. The older type planning was re-organized in accompany with these occurrences. Thus, Settan type had been formed in this region by the first half of the sixteenth century.

1) It has been defined that the insula is a three to four story building in fairy large size, with shops on a ground level and rented to the public, as a rental apartment house. In one hand the definition mentioned above is acceptable according to researches and studies having been done in the past, but otherhand we should reconsider insula more widely according to the new criteria based on of their architectural quality and size. 2) The number of <<insula>> is shown as 46, 000 on the Regionaries, a precious ancient record. However a conflict is occured on their number of existed units, if we define <<insula>> as a rental apartment according to the old criteria of <insula>, the documents mentioned abobe the regionaries, therefor <<insula>> should be defined differently from <insula> by the reason mentioned above and we could guess there might had been some provisions in the Roman cities for their own on using the term of insula. At present, the number shown as 46, 000 might be indicating that of the gates facing to streets on a ground level.
