There are stresses of many directions in the structures, while few studies on the failure criterion of concrete. It may failure be said, it is not given how to find the yield or failure strength under combined force, as bending moment, axial force, shearing force, ets. We have had a fundamental study on the failure function of concrete to make clear the ultimate strength of concrete members. In this part, it is assumed this function is given J_2^<1/2>+αJ_1=k^*, and it is discussed how to apply for the limit design. We obtain α=0.567, k=0.847 f_c, using plastic potential theory referring to the data of past experiments. * J_2^<1/2>={(σ_1-σ_2)^2+(σ_2-σ_3)^2+(σ_3-σ_1)^2}^<1/2>, J_1=σ_1+σ_2+σ_3 σ_1〜σ_3 : principal stresses.

In this paper the results of investigation of live load on floor in the 12 office buildings of reinforced concrete construction or steel-reinforced composite construction is expressed. Buildings investigated were the newly built buildings completed after 1955. The object of investigation was divided into two. One is for main office space and the other for subordinate office space (parlour, meeting room, directors' room, stack room, computer room, etc.). The matters for investigation were as follows : (1) Ratio of floor area occupied by articles (furniture, desk, chair, papers and file cabinet, book and book cabinet, locker, miscellaneous articles for business) to total floor area of a room. (2) Mean value of total weight of articles per unit floor area. (3) Mean value of total weight of articles divided by the floor area occupied by articles. (4) Load by human crowd per unit floor area. (5) Live load (weight of articles plus load by human crowd) (6) The value of (2)/(5) (7) Mean value of floor area divided by the number of office workers of a room. The office buildings recently built are different from old buildings in the points of function of office, structural design and others. Therefore, the value of design live load on floor should be reexamined by new date. The authors believe that the results expressed here will be available for the above aim as basic data.

Not a few reinforced concrete buildings were heavily damaged in Tokachi-oki earthquake in 1968, Japan. But the ratio of heavily damaged to total buildings was fairly small in spite of their structural strength being thought to be nearly coordinate. At the beginning of this investigation, a sort of resonance phenomenon between the predominant period of ground and the natural period of building was thought to be one of the most important element which caused to structural damages. As the results of our investigations, it cannot but be concluded that the damages could not be explained only from the resonance phenomenon between structure and ground. A more important factor which is the frequency density of predominant peak included in an original ground motion was found through the investigating works, and the factor is called frequency selectivity in this paper. From many observed data obtained from micro-tremor and after shocks, it was proved that the frequency selectivity had a close relation with the earthquake damages of building in Hachinohe and its suburbs.

At the present time, the method of analysis most commonly used for the earthquake response of structure is based on the assumation that the soil ground vibrates in phase and same amplitude just beneath the foundation. But it is very doubtful whether the buildings having horizontally large scale as school building and apartment hause vibrate as if they are rested on an artificial vibration table. Such a question has been talked about among earthquake engineers for a long time. The greater part of damaged buildings were occupied by school buildings, that is to say, the buildings having horizontally larger scale in Tokachi-oki earthquake. Many after-shocks were observed in Hachinohe district with the objects of inquiring the causes of individual damages and investigating the general correlation between ground motion and building response. As the results of those observations, it was proved that there were remarkable phase differences among the movement of every point of building foundation during earthquake motion. The correlation between the movements of building foundation and its surrounding ground was also made clear. The correlation was found to be mostly affected by the wavelength which appeared ground surface. The correlations between ground motions during earthquake and the response of building are subjectively discussed in this paper.

The purpose of public investiment is to improve our living environment. Its effects should be measured in terms of its benefits to our life in an urban living environment. In doing so, it is fundamentally important to understand the structure of the relationship between urban life and physical elemens of living environment. As the first step of my brave attempt to establish life utility function which measures the effectiveness of living environment in psycological aspect, i. e., dweller's satisfaction, this paper tries to quantify psycological satisfaction and also to show its structure. Method of successive categories is applied to quantify the average degree of satisfaction in a cell. Based upon the quantification, correlation coefficient matrix is obtaind, which anables to use factor analysis in analyzing the structure of satisfaction. As a result, four aspect of value are recognized : safety, healty, efficiency, comfort. These four factor agree with four fundamental criteria proposed by W. H. O. And they are integrated into one scale which I named level of environment Profile value difined by factor loadings is regarded as utility of physical elements in urban living environment.

Housing career is generally studied by researching all process of change of residence on a family. But on this report, it is studied by former residence and reason of change of residence, because our object are mostly young families. They changed their former residence from the reasons of marriage and employment etc., and especially 30〜40% of former tenants of tenement-houses by private enterprises require better conditions. And we consider it housing demand that they wish to improve their low housing level by the change of their residence. It appears from their demand on the space for their childre, but the realization is prevented by their income grade and by their occupation which relate the location of housing. From these conditions, we could know that there is no proper supply which is in conformity with their demand.

This paper aims to investigate the morphological development and its peculialities of Heian-kyo (now Kyoto), an ancient capital of Japan, by tracing change of some actions of men on her urban spaces. This means also to investigate some interrelation between morphological form and men's actions on it. The traceable actions by historical records are mainly limited to that of ritual ones, such as parades of Mikado or nobilities. 1) Mikado's parades to Kasuga shrine and Iwashimizu shrine. These shrines are situated to the south of the capital and parade from palace, which was usually in northern part of the city, went down across the city. Before 1100 most of these parades took Suzaku-Oji, the central N-S street as Cardo maximus in the ancient Roman cities. But after 1100, gradually Suzaku-Oji became to be abandoned and, instead of it, Omiya-Oji or Higashitoin-Oji which were other N-S main streets on eastern part of the city. This fact corresponds to the breakdown of geometrical strictness of the capital's form and its sprawling development to ards the east. It also means the decay of ritual feature of urban space which had been an outstanding character of ancient capital, originated in Chinese city concept. 2) Mikado's parades to other shrines or detached palace, the same inclination is observed.
