The purpose of the present paper is to establish a simulation method of the behavior of fresh concrete at its mixing, placing, consolidating, etc. As one of the method to estimate the flow and deformation of fresh concrete, a method of visco-plastic finite element analysis is proposed, and some analytical results are shown in this paper. In the analysis, slip resistance force between boundary surface and fresh concrete can be considered, and the dynamic behavior can be analyzed by calculation of the retardation of velocity change. The results of simulations are in good agreement with those calculated by simple theoretical equations about some examples such as flowing in pipe, parallel-plates plastometer, slump test, and the adequacy of the proposed analytical method is confirmed.

This paper, taking Futsuka-machi, Tozan-Nakaokutama Village, Iwai District in the area of Sendai clan as an example, clarifies the historical process of the formation of the town belonging to the countryside in Tohoku area in the Edo period through an analysis of the town form and its historical materials. This town originated in a late medieval small castle town which had been founded under a fort, and this restricted its reconstruction in the early Edo period (about 1639). Features of this reconstruction are as follows ; (1) Machikonoshn who were the habitants of Machiyashiki (townhouse) established their own community, and reconstructed the town by themselves. Particularly they built a streight street which had a L-shaped bend at the south end of the town. This arrangement arised from their consciousness of the regularization of Mchinami (townscape on a street). (2) On the east side of the street lined Machiyashiki, and on the west was the huge farmhouse, originated in Zaike (a type of medieval farmhouses), which didn't belong to the town community. Such difference of dwelling places on each side of the street had been succeeded since the late medieval ages. (3) The area of Machiyashiki is of a small scale as compared with others in this village, and its frontage was divided almost equally. However the habitants had large differentials in landholding. This is one of the characteristics of the townplanning in Tohoku area in the early Edo period.

A number of investigations concerning elastic stability of shell type structures subjected to quasi-stasic conservative forces or time depending dynamic forces. However there have been no study for the behavior of them under the action of quasi-static nonconservative forces. In this paper the authors show an analytical study of stability for clamped spherical shells subjected to combined load composed of quasi-static uniform hydropressure (conservative force) and a frictional force (nonconservative tangential follower force). Similar loading conditions, for example, can be realized when an object is moving fast under deep soil or liquid. And it is found that dynamic instabilities take place at some equilibrium states. These tendencies are remarkable in the cases of moderatly deep shells. The authors consider such phenomena will be of interest and important from the view point of structural engineering.

Christopher Dresser (1834-1904) was an unique designer in the history of modern design. Many art historians, for example, Sir Nikolaus Pevsner in his "Pioneers of Modern Design" and Robert Schmutzler in his "Art Nouveau-Jugendstil", highly appreciated him as a revolutional designer. Dresser's design seems very functional and "modern". But it was not only the result of functional study but also the result of looking into fundamental form. It is true that he studied function of the shape of the pot, but it was only one of his interests. At the same time, he was deeply interested in the study of natural form and of an artistic arrangement of decorative forms. In 1873, he published "the Principles of Decorative Design", which had close relation to Owen Jones' "The Grammer of Ornament" and even to A.W.N. Pugin's "The True Principles of Pointed or Christian Architecture" in 1841. These authors were inquiring into fundamental form and arrangement of decoration. Pugin's principles were based on the Catholic religion, Owen Jones' principles were based on the natural forms. And Dresser found the Energy and the Force as his basic principles for design. Dresser's principles, however, were not completely abstruct ones. He, then, caught a chance to visit Japan. His travelling through Japan from 1877 to 1878 shows characteristics of the principles of his design. He visited Yokohama, Kobe, Osaka, Nara, Kyoto, Nikko, Tokyo and many other places. He was interested in many of Japanese designs, especially, in such decorative designs as mausolea at Nikko and Shiba. It seems that the decorative arrangement in Japanese Art greatly inspired him, and that he had confidence that his principles were true. After returning to Britain, he created many revolutional designs. In these designs, however, we could not find any Japanese motives. But he must have been greatly inspired by Japanese Art. He was inspired not by forms but by the method of convention and arrangement of them. Contents of the thesis are as follows. I. Introduction II. Chronology III. Dresser and Cole's Circle and the South Kensington IV. Travelling to Japan in 1877 V. Controversies on "Japanese Village" and against J. Conder VI. Dresser's Principles

Yokohama, one of the most famous international port cities in Japan, is excellent in its urban design. It is of course ascribed to the superiority of the city planning, and in addition to this, the planning is noticed to be very attentive to even such public facilities as crematoriums. This fact has been clarified in the present study in relation to the history of the city formation of Yokohama since the Meiji era.

The seismic isolation retrofit of the main building of the National Museum of Western Art required excavating the foundation ground under the existent building and installing isolation devices beneath the existing footings. Before the installation of isolation devices, it was necessary to construct piles beneath the existing footings in order to support the weight of the building temporarily during excavation process. The piles were made of steel pipe segments, and were driven by oil jacks utilizing the weight of the building for reaction force. During the retrofitting process, the subsidence of the building supported by the piles were monitored and controlled to avoid causing damage to the superstructure.

In order to clarify post local buckling behavior and plastic rotation capacity of steel beam-columns, cantilever steel beam-columns of H shape cross section were tested under constant vertical load and alternating horizontal load. The test program was composed of two series; fifty nine specimens of Series I tested at large amplitude of plastic deflection, and thirty three specimens of Series II tested at small plastic amplitude. Main parameters involved in the tests were the width-to-thickness ratios of the flange b/f (2b, f : width and thickness of a flange, respetively), ones of the web D/w (D : depth of a cross section, w : thickness of a web), axial load ratios n (P/P_y, P : a constant vertical load of a specimen, P_y : axial yield load of a specimen), and material pro perties of the steel (mild steel and high strength steel). Values of the parameters b/f, D/w, n are as follows : b/f=6〜16 D/w=17〜65 n=0, 0.3, 0.6 In this paper, the test program and test results are reported. Some observation from the test results are as follows : 1) Not only width-to-thickness ratio of the flange but also one of the web and axial load ratio influence on the post local buckling behavior of the steel beam-columns. 2) Not only with axial load but also without axial load, the members subjected to alternating bending shrink due to unbalance of axial load carrying capacities of the buckled flanges.

‘Crofting’ is the traditional tenancy system including traditional culture, land use system in Scotland. Farmers are called ‘Crofter’ renting land from land owners. Crofting village has similarity with mountainous villages in Japan which have a traditional bond, collective work, traditional way of thinking. The paper aim to clarify the present situation of crofting village in viewpoint of sustainability and spatial construction principal. The principal is that keeping fertility and equality among crofters which made spatial character of crofting village, whether principals of Japanese village tend to protect lands from disaster and utility of water supply in general.

This paper aims at making clear from both historical and spatial aspects how and by what reasons the owner-ccupation has spreaded in urban areas of Japan by means of taking the cases of 24 main cities into consideration. The conclusion concerning to historical change is summarized as follows: 1) Before the war, the private renting was the dominant tenure of urban housing excepte for housing located in the suburbs of the big cities and several new industrial cities rapidly urbanized, where the sign of the growth of the owner-occupied sector was emerging. 2) The remarkable increase of the owner-occupied ratio from 22.3% in 1941 to 41.3% in 1948 causes to an enormus degree by the war damage and the housing constructin immediately after the end of the war, which determined the changing direction of housing tenure after the war. 3) For the postwar period, the change of a distrubution ratio of housing tenure has been caused mainly by rapid urban growth, especially the intensive concentration in metropolitain areas throughout the period of the high economic growing and the amount of new rental housing has sharply reflected on it. While the number of owner-occupied housing has constantly increased throughout the same period and as compared with the renting, the owner-occupation is more stable and accumulative as tenure type. On the other hand, through the spatial ananlysis, it became clear that there were several differet patterns in the increasing process of the owner-occupation, the main two patterns are as foolows : 1) Metropolitan type・・・ After having accumulated the private renting, owner-occupied housing has increased in parallel with the real urbanization. 2) Local type ・・・In the cities where urbanization has been inseparably related to the incorporation of rural areas, the owner-occupied ratio has risen through the increasing number of a farmhouse and being based on it, the real urban housing has been formed on the side of the owner-occupied sector. Most of cities of Japan are subject to the latter model and it means that the tenure of a farmhouse has significantly contributed to the expantion of the owner-occupation. The ratio of the owner-occupied has been determined not only by the factors which caused the change in the national level as mentioned above, but also by the special factors of each city such as historical and cultural characteristics concerning to the choise of housing tenure.

Recent buildings have been more unburnable than before because changing of construction methods, progress of building materials, preparation of the related laws and regulations and so forth. But buildings have been more unextinguishable contradictory, and extinguish time need more longer than before. There are problems ; Is not the water application ratio low ? How much is the water damage area even if the water is used for extinguishing ? If we survey these problems, it is useful in order to make fire fighting planning. Then we investigated these items as a part of basic study on the extinguishing of the building fire.

本稿は,建築家J.B.フィッシヤー・フォン・エルラッハ(1656-1705)の考案したシェーンブルン城第1案(1688)の建築モチーフの考察と,その形態構成表現の柱ともなる彫像作品群の象徴表現の解釈,即ち象徴性の意味関連を考察する事(イコノロギー解釈)を目的としている。既に前稿[I]で,この計画案の要素となる各建築形態が独立的モチーフであり,合成的表現によって,統一ある運動をもつ一つの全体として表現されていることを指摘した。本論では,この構成技法との関連性を踏まえて,建築モチーフの由来及び特色を考察し,またイコノロギー的表現においては,各彫像群の寓意的解釈に図版全体の幾何学的秩序を関係付けた象徴表現の分析をしている。即ちこの計画案の意味内容に,部分と全体との間の必然的統一関連性を求め,寓意像の存在理由に新たな解釈を加えようとするものである。本論では,この図全体の4つの段階ごとの集まりの分類化,つまり城郭部分,2つの庭園テラス部分,そして主要な彫刻作品のある最下層テラスに分け,分析することで,計画案の個々の造形物の由来と特徴を明らかにしようとした。その結果,この計画案が古代ローマのフォルテューナ神殿復原図,また従来,抽象的にしか指摘されていなかったフランスのサン・ジェルマン・アン・レーの影響を,形態構成分析の考察に基づき,より実証的にその直接的影響を指摘した。また彫像作品間に存在する幾何学的構成表現が,象徴表現となっていると云う筆者の指摘は,城郭上方の皇帝像が下層の4つの彫像群を放射状に支配すると云う構成に基づくものである。これは,太陽神に姿を借りた皇帝像が「世界支配」を象徴化していると云う指摘である。それは,この調和的統合表現によって,一つの観念形態を象徴化するイデオロギー表現の存在を意図したものであろう。最後に,この計画案のイコノロギー表現に関与していたとも云われる哲学者ライプニッツの「調和の哲学概念」の関連性を述べているが,前稿[I]の考察も含めこれは彼の哲学概念の視覚上の表現であると云う従来からの観念的指摘に対する,一つの実証的解釈の試みともなっている。

This study deals with the proposer and the first idea of the Templo de la Sagrada Familia in Barcelona, by examining the origin and development of the Asociacion Espiritual de Devotos de San Jose founded in 1866. As a result, it is made clear that Bocabella was not only the founder of the association but also the poposer of the temple, and no the father Jose Mananet. From the beginning the purpose of the temple was very spiritual and symbolical as well as his association.
