This paper is to follow the previous part 1 and 2, in which basic properties and responses to several conditions of the environment of Gypsum are studied. In this paper experimental results and some considerations on mechanical properties of cast Gypsum are explained and concluded as follows. The compressive strength of cast Gypsum which is made in the season when the monthly average temperature is lower than 18℃ or with the temperature arrangement, is possible to be attained constantly over 150kg/(cm)^2 under wet condition and over 300kg/cm^2 under dry condition. The young's modulus of cast Gypsum is around (10)^5kg/cm^2, almost half value of Cement Concrete, and decreases by absorbing water as in the case of the compressive strength. Cast Gypsum has very small bond strength between smooth surfaces like the round steel, but the bond strength over 10 percent of the compressive strength can be obtained by using deformed bars. The creep of cast Gypsum is prospected larger than Normal Portland Cement. By short time experiments the creep rate of cast Gypsum under dry condition becomes begger than 1 after 1 month loaded with 33 percent stress of the compressive strength. The tensile strength of cast Gypsum is from 3 to 10 percent of the compressive strength. It is sure that Gypsum is inferior to Cement Concrete in many mechanical properties mensioned above, but there are cirtain posibilities to use cast Gypsum as structural materials in buildings.

The purpose of this study is to clarify the mechanical properties of a transversely-isotropy. A transversely-isotropy has 5 elastic coefficients. Assuming that the strain-energy-function is positive, and that the governing partial differential equation is elliptic. The solutions of concentrated forces acting on a transversely-isotropy is solved by Fourier transformation. This method is also effective for the same problems of an isotropy.

This paper develops a new analytical technique for the assesment of stochastic earthquake responses of a multimass building structure with bi-linear hysteretic characteristics by extending and making use of the previously developed analytical procedure, the availability of which has already been ascertained where the building structure is a single degree-of-freedom system under quasi-stationary white noise excitations. After the availability of this new technique for the multi-mass structural system was first confirmed by comparatively investigating the non-stationary response processes of a two degree-of-freedom system subjected to quasi-stationary white noise excitations through the simulation technique and this new one, it is studyed what influence such the elasto-plastic dynamical parameters as the second slopes and the elastic limit deformations associated with bi-linear hysteretic characteristics has on the stationary r.m.s. relative displacement response distribution.

In the previous paper, we have reported on the vibrational characteristics of restoring force model exppressed in terms of power function and a method of converting general hysteretic systems into the power functional hysteretic system. In this paper, we describe three methods for seismic analysis of the power functional hysteretic system. One of the methods is accurate but tedious, and the others are approximate but brief in process of analysis. Examples of numerical calculation of seismic analysis will be reported in a later paper.

This paper describes an analytical method predicting the dynamic reliability for elastoplastic structure. The proposed mehtod will be discussed in succeeding three reports. First, probabilistic model for analysis is developed by the assumption that the elastic-plastic response to random excitation can be divided in two parts; elastic random response and plastic response based on empirical evidence of symmetrical permanent set. By the analytical model, an approximate solution of first passage time to the yield level during the part of elastic random vibration was obtained, and compared with the results by the Monte-Carlo technique.

This paper investigates the difference and similarity of the damages in Tokyo caused by the Earthquake Ansei Edo, 1855 and the Great Kanto, 1923. The results obtained may be summarised as follows. On the Earthquake Ansei Edo, the large damages of houses, storehouses and temples are all caused at the east part of Tokyo. From this point of view, it is found that on the regional differences of damages, we must take account of not only the ground constitution but also the effect of the epicentral distance.

The Reclaimed area of the Urayasu district in Chiba Prefecture is composed of an alluvial deposit of more than 40 meters depth. This alluvial deposit consists of an upper sand layer 15 meters thick (N Value 0〜15) and a lower silty clay with depth of 25 meters or more (N Value 0〜5). Successive ground settlements measuring 7〜11cm per year have occurred due to compressive consolidation. Through the alluvium, four steel piles of φ600×14 were driven into a diluvial stratum. Then, for the past 2 years, the axial forces due to the surrounding soil settlement have been measured. The results are summarized as follows : (1) Maximum axial force is 320 ton in a 50 meters pile, and 200 ton in a 40 meters pile. (2) These axial forces result from the negative frictions caused by consolidation of the lower silty clay. Friction stress τ of the lower silty clay is equivalent to 0.3δ^^-_v, which is well known. (3) Friction stress τ of the upper sand is unexpectedly smaller than that of AIJ recommendation (τ=3+N/5), and evaluated as τ=N/10 at most.

This report is the first of the series works to find what house plan fits the households with the handicapped. Main aims are researching the effectiveness of the house type with the 〓D〓 (dinning space, its main type DK), and with the 〓L〓 (living space, its main type L/DK). Main results of this research are as follows : 1. In owned houses the 〓D〓 type is introduced to the extent of about 50%, and the 〓L〓 type to about 25%. In rented houses 〓D〓 type accounts for about 20%, and the 〓L〓 type nothing. 2. In owned houses the boarded DK is used well for having a meal by not only the handicapped but also other members of households. 3. However the eating style in the DK is not always the Western. The Japanese squatting style accounts for 25% of cases using DK. 4. In case of not using the dinning space, the adjacent room to it is usually elected as dinning and public space. 5. The eating style wanted by the handicapped is nearly satisfied in owned houses, but not enough in rented houses for their lesser conditions of the DK. 6. The 〓L〓 type, that make it easy to transfer for the handicapped all over the house, are not so spread. 7. It is different by the 〓L〓 type plans how main house living behaviors overlap in the 〓L〓. In case of L/DK it is easy to use L as others without dinning room, and in case of the LD/K and LDK to use the LD or LDK as dinning room and others. The latter is able to make fit as one room using for simple small household. 8. It is obviously inclined that some behaviors crowd in a living room. Therefore, in case of the houses with the 〓L〓, each room is kept to exclusive use, but without the 〓L〓 the confusion by crowding some behaviors in Japanese mat room increases.

This paper consists of three parts. The first is to find factors concerning the aggregation of establishments in Fukuoka City, the second is to analyze the correlation between each establishments where they deside their locations and the third is to calculate areas of each establishments. The factors on the effect of the aggregation of establishments consist of commerces around the locations, aggregation of manufacturings or populations and accessibility for mass transit. To make clear the correlation between each establishments, we use the Cluster Analysis founded Yule's coefficient of association. Then we make a picture of dendrogram from this analysis and research the degree of correlation between each establishments. The constructions, publishing, printing and allied industries, wholesales and retails, finances and insurances, real estates, eating and drinking places and automobile maintenances and related service show the strong degree of correlations. The area occupied by one establishments is 261.50m^2 and by one employee is 29.96m^2.

M. Borissavlievitch explique la beaute par l'Einfuhlung et la facilite de la perception visuelle qu'il appelle le principe de moindre effort. Il soutient que l'architecture est un art du temps du point de vue esthetique. Car, la perception visuelle n'est pas simultanee, mais successive, c'est-a-dire elle se passe dans la duree du temps. Au moyen de ces deux points de vue fondamentaux, il analyse la beaute de la forme de l'architecture, particulierement celle de sa facade. Il emploie, pour l'analyse, les termes tres connus concernant la theorie de la beaute des formes, par exemple, rythme, symetrie, asymetrie, proportion, harmonie et composition. Mais il tombe quelquefois en desordre a l'occasion de l'emploi de ces termes, parce que leur definition est equivoque. Et enfin, il montre deux lois pour l'harmonie d'une composition architecturale, la Loi du Meme et la Loi du Semblable. La premiere demande que les elements d'une composition, qui sont toujours rectangles, soient memes et la deuxieme qu'ils soient semblables non pas reellement ou geometriquement, mais en apparence. Cependant la difference entre un rectangle semblable geometriquement et celui semblable en apparence n'est pas determinee, et elle est quelquefois si grande qu'on doute de l'efficacite de la Loi. Son esthetique est, apres tout, subjectif contrairement a son intention, et elle n'est pas suffisamment scientifique.

In 1870s, young architects began to revolt against established revivalists. Among these architects, John James Stevenson took very active part in the rebellion. J. J. Stevenson was one of the originator of the "Queen Anne Revival" in 1870s. At the same time, he was a severe accuser of restoration. In 1877, he gave a speech on "Architectural Restoration; Its principles and Practice" at the R. I. B. A. In his speech, he criticized restoration works by G. G. Scott, G. E. Street, and E. Viollet-le Duc. Above all, he accused Gilbert Scott in detail, making reference to his works at Canterbury, Glasgow, Chester, and St. Albans. A reply, of course, was made by G. G. Scott to J. J. Stevenson's paper at the R. I. B. A. meeting. Moreover, Scott wrote down the matter in his "Personal and Professional Recollections", in which Scott reproached 'Anti-Restoration Movement' and 'Queen Anne Revivalism' together. Certainly J. J. Stevenson was a Queen Anne Revivalist as well as an Anti-Restorationist. More precisely, he was a Queen Anne Revivalist first, and then an Anti-Restorationist. He took in Ruskin's theory of Conservation so as to revolt against established revivalists.
