Experiments have been performed to investigated vaccum effect. In vaccum pacage aggregates and cement particles can be absorbed with water ideally. Generally some of cement particles contact with air or each other. This phenomena is undesirable as for as compressive strength of concrete. Then experimentes were carried out to improve absorption between water to aggregate and cement particle. First experiment was carried out on bond strength between cement paste and aggregates. Relationship between bond strength and age was shown in Fig. 2. Bond strength in vaccum was not greater than in air. Tested surface in vaccum was observed very clear and in air it was recognized void. (See photograph) Second experiment was carried out on compresive strength of vaccumed concrete. It was vaccumed after cement and and aggregates were cast in the place and three minutes later water was poured in it. Then concrete was mixed and cast in test piece. Consequently four percentage of water was reduced from concrete and water……cement ratio was improved four percentage. Specific gravity of vaccumed concrete was greater than in the air of concrete. Compresive strength of vaccumed concrete is greater 10〜20 percentage than in the air of concrete. Relationship between compresive strength and age is shown Fig. 10. Coefficient of contribution of water……cement and cement volume occupied neary 100 percentage. Vaccumed procedure and air content are not significant.

Authors propose in this paper ascale for evaluating intensity of earthquake motions from the point of view of antiseismic design in which structure is permitted plastic deformation, and from the point of view of earthquake damage to structures. Usually, as this kind of scale, maxmimum magnitude of acceleratien and respones spectrum are used, but there were several cases in which little damage to structures are inconsistent with large values of maximum magnitude of acceleration and response spectrum. For example, maximum magnitude of acceleration of the earthquake motions recorded at Kushiro in 1962 is 513 gal, and its response spectrum shows remarkable peak at T=0.33 second (Fig.1), that is, 2.2g for 5 percent damping and 4.8g for 1 percent damping. But little structures suffered damage. Then they propose to understand these kind of phenomena by means of elasto plastic response of one mass system due to earthquake motions. About the earthquake motions at Kushiro, elastoplastic response for T=0.33 second decreases to one sixth of elastic response (Fig.7), and ductility factor is not so large (Fig.5). Elasto-plastic displacement responses expressed as same as response spectra have linear relation with T (in log scale) for T=0.1-1 second, so the value for T=1 second may be used as a scale for intensity of earthquake motions (Table 1). Elasto-plastic displacement responses are roughly constant for any ultimate strength Q_y within right range. This property mav be used for minimum required ultimate strength to allowable ductility factor of struture Eqs. (2), (3). As the values of Sa' may generally be got from elasto-plastic displacement responses of Q_y=0.3g, 0.4g. This method is good for 2-3 in ductility factor.

Author calculated the response analysis on the vibration of the Elasto-plastic steel space structure due to the strong earthquake motions by using the electric digital computer, and discussed the influence of the displacements and the progression of yield members in the Elasto-plastic steel space structure. This paper is the sixth report of the series on the dynamic response analysis of the space structure for the earthquake. These results are as fallow : (1) It is shown that the maxmum displacement of the grid type due to Earthquakes is larger the one of folded, pyramidal and H. P. type. (2) In this case the yield members approach to the members of the maximum shearing force due to the dead load in the steel space structure.

The multilayer plates defined in this paper are made of materials obeying Hooke's iaw and Young's moduli of them vary over the thickness of the plate. A system of equations is developed for the theory of multilayer plates which takes into account the strectching, bending and shearing deformability. The manner in which the equations of the theory are obtained consists in an application of two well known variational principles (the complementary energy minimum princeple for stresses and the potential energy minimum principle for strains). The simultaneous use of different variational principles gives the upper and lower bounds of potential energy of elastic deformation of mutilayer plates.

筆者等は前回の論文で, 天空輝度が高度θに応じて変化し, その分布がB(θ)=B_z(1+2sinθ)/3, B_z=天頂部の輝度, で表現される場合に対して, 簡単な直線形態をもつ開口に関する直接昼光率を求める計算式を導き, 2, 3の計算例を示した。それらの式は従来のように一様の天空輝度を仮定した場合の計算式より複雑で, 利用の簡便化のためには, 適当に数表化または図表化しておくことが必要である。ここでは, 前論文中で誘導した諸式のうち, 水平面照度に関するものの計算図表を掲げ, 応用例として求めた鉛直長方形開口による水平面直接昼光率の分布計算例を紹介する。

The buildings of the Japanese shrine develop into two courses. One of them is based on the Japanese Style from ancient times. The examples taking this course are Ise Zingu and Izumo Taisha and these shrines keep of ther initial style under no influences of the style of Buddist buildings. Taking another course the buildings of shrine have the ornamental detail of Buddist buildings. The majority of shrines in the middle age develop into the latter course. Nikko Toshogu is at the zenith of this course. The purpose of this paper is to investigate the ornamental details and its regional tedencies of the buildings of shrine. The ornamental details are employed actively in the buildings of shrine at the end of the 13th century and classified into following three types; (1) Wayo : This style is used from Nara periad in Japan. (2) Daibustuyo : These styles are introduced from China in early years of the 13th Century. (3) Zensyuyo : These styles are introduced from China in early years of the 13th Century. These apears the regional tendencies on the employment of the ornamental details after the 14th century. The shrines in Nara and Southern Kyoto have details of the Daibustu Style. In Osaka prefectures, the shrines have the details decorated gergeously. The details of the shrines in Siga prefecture are simpler and plainer than that in Osaka. The chronological tendencies after the 14th century in to be found the regional characters in the limited area.
