In previous report streaming potential of aggregates and bond strength between aggregates and cement paste were investigated. Bond strength was affected by surface roughness andρpotential, i. e. bond strength increased with inρpotential and is stronger in the case of rough surface than smooth surface but this relation is not linear and the rate of increase becomes slower with the increase inρpotential. In this paper membrane potential of aggregates was investigated. It is belonged to the electrostatic phenomena in the electrochemistry. In previous report streaming potential is belong to the electrokinetic phenomena. Membrane potential of aggregates are affected by chemical constituentes that is less the content of SiO_2, greater the membrane potential and greater the contain of CaO+MgO, less the membrane potential. This is the same phenomenon as streaming potential. Membrane potential of artificial aggregate was affected by chemical constituent and burning temperature, that is less the content of clay, greater the potential and higher the burning temperature, less the potential.

This paper treats salt-tight efficiency about test pieces of various concrete and finisfings, as amplification of another report "Research on Wearing of a Reinforced Concrete Building standing by the Seaside". It consists of next three experiments. A. Salt spray test of 500 hours. B. Natural disclosure experiment at three seaside of Shirahama, Miyazu and Kobe. C. Fundamental experiment of permeation and capillarity. The main results obtained are as follows. 1. Capillarity height of simple tube is almost linear with density of concrete. 2. Capillarity height of two faced plaines is maximum when depth of their filler is 50-100μ. 3. Polymer mixed concrete is most excellent in the test of cappillarity height, rate of suction, and salt-tight efficiency.

屋上に壁面を組上げ, Re数が10^6台において風圧の測定を行なった。結果は次のように要約出来る。1)水平断面周囲の風圧分布は, 負圧の値はやや小さいが, 迎え角の増大にともなうその変化は, 今までの結果と一致する。上端付近の側面負圧は下より大となることがある。2)台風時の測定で, 突風時において風上面に変動量の大きな正圧を記録した。風上面の風圧は各点間の相関も高く, 構造体に作用する変動風力を考える場合, 背面の負圧に比べてはるかに重要である。3)風上壁面上の風圧変動を, 小さな平板上のそれと比較すると, 高い周波数成分が明らかに少なく, 風上面の風圧変動が, 構造体自身の影響を受けていると思われる結果を得た。4)頂部の一隅にはった平板上で, 迎え角が45°付近のとき, 円錐状渦の発生が認められ, 縁に沿って-3.0をこえる高い負圧の, 間歇的な発生が記録された。

As the typical example of the tension member of which stress concentration must be considered, a plate with a round hole was adopted, and the behavior was investigated until its ultimate state theoretically using the numerical analysis by finite element method to the elastic-plastic range on the basis of the flow theory and experimentally. And it has been shown as the case of the member of which stress concentration is negligible that the elongation capacity of the steel plates of which section area change along their length was controled by the yield ratio of the material used. The larger the value of the yield ratio, the smaller the elongation capacity of the member. It may be said from this point of view that it should be careful when the high yield strength steel be used in tension member bolted or rivetted at its end connection or in tapered or notched shape because the high yield strength steel generally has the high yield ratio.

Author experimeated the Elasto-plastic flexural behaviours of the steel truss member, and discussed the equivalent beam for the steel truss member. This paper is the fourth report of the series on the dynamic response analysis of the space structure for the earthquake. These results are as follows : (a) It is shown that the period of the equivalent beam for the steel truss member approaches to the period of the steel truss member. (b) In the experiment it is shown that the calculated deflection is smaller than the observed one. (c) It is also shown that the maximum load of the virgin compression is the largest under the alternating loads, and the deflection curves of the unloading approach to the curve of displacement for the maximum load of the virgin compression.

The standard objects are square walls 270cm wide and 270cm high, standing on a open air field, colored with red, blue yellow and black paint. Their distances from the subjects are 100m, 300m, 500m, 700m and 1, 300m. The comparative objects are various small square figures drawn on papers which are observed at the distance of 50cm. The average of the subjects are 7.67 persons each on one experiment. The conclusions obtained are : 1. There occures somesize constancy viz. The remote wall appears larger than its geometrically diminished size. The corelation between the apparent size (P) and the distance (D) is shown as a hyperbola : P×D=7, 500 r=6.20 (P in mm, D in m) The various averages of the degree of constancy (P/S) is shown in Table 6. 2. Red appears lager than other colors especially when the experiment is commenced at long distance. 3. The degree of constancy of red becomes larger as the distance increases when the experiment is commenced at long distance. 4. Black appears a little smaller than other colors. 5. The colors, except blue, appear larger commenced at long distance than commenced at short distance.

The purpose of this paper is to analyze journeys from the central sterile and supply department (C.S.S.D.) to the nursing units, the out-patient department, the operation department and other departments in the hospital and to gain information for the design of C.S.S.D. Six hospitals were chosen for the study of the actual traffic to and from the C.S.S.D. The results are as follows. 1) The journeys are divided into two types : (1) routine supply and (2) extraordinary supply and the latter is important for the planning of C.S.S.D. 2) Most of supplies to the nursing units and O.P.D. are served by the routine supply. Frequency of extraordinary supply to a nursing unit is less than once a day and to O.P.D. is very low, too. 3) Supply to the operation department has difficult problems from the architectural point of view. As the frequency of emergency supply is four〜eight times in an operating case, the location of C.S.S.D. is required to be close to the operating suite. In larger hospitals, two supply facilities should be provided; one is exclusively for the operating department and another is for the other departments.

Various theories have been expressed with regards to the religious meaning of the Tjandi Barabudur, the most famous buddhistic monument of the Hindu-Javanses Art in ancient Jave. A straight line connecting Tjandi Barabudur and Tjandi Mendut passes Tjandi Pawon. By the archaelogical surveys made so far suggested that there must been some connections between these monuments, and the existence of a large scale buddhistic temple consisting these three sanctuaries and some more others, such as a vihara, etc. And from this point of view, the religious meaning of the Barabudur would be a "Stupa". Beside, the author spent a considerable time on the site recently and felt his personal inspiration about this problem, and the author determined subjectively that the religious character of the Barabudur would be a "Stupa". Finally, from the architectural point of view, the Barabudur was analized technically. The Barabudur itself has been built around the top of a natural hill, which consequently forms the nucleus of Structure. It is a quite defferent the structural form from any other monuments in India or in the wide sphere of Indian-Art and this fact proves that the Barabudur is an absolutely pure creation of an architect of unusual talent. So the religious meaning of this monument could not or should not be determined only from it's architectural composition.
